Description

[Technical Field]

[0001] The present invention relates to a solar panel disassembly device for disassembling solar panels (the portion remaining after removing exterior components such as frames from a normal solar module), and more specifically to a solar panel disassembly device that can precisely disassemble a solar panel into glass sheets and the remaining film-like laminated portions other than the glass sheets. [Background technology]

[0002] The development of clean energy, which reduces environmental pollution, is accelerating. Clean energy development is being promoted in various ways through government-sponsored projects. Clean energy technologies include not only technologies for managing produced electricity, such as energy management, transmission, and storage, but also a variety of renewable energy technologies that utilize biomass. Research is ongoing into electricity production technologies, such as solar power generation and wind power generation, which use natural energy without using fossil fuels.

[0003] In particular, solar power generation has seen significant improvements in power generation efficiency since its development through continuous technological improvements, and as a result, it continues to secure its position as a noteworthy alternative energy technology. Solar power generation facilities are on the rise due to their advantages of being easily applicable in areas where it was difficult to install conventional power generation facilities, having almost no impact on the environment, and being able to be installed using existing buildings and facilities.

[0004] However, even in solar power generation facilities, solar cells must be replaced or disposed of when their useful life expires, which poses maintenance issues. As the number of solar power generation facilities, as well as the application units and area, expands, large-scale replacement and disposal of aging solar cells becomes necessary. However, many solar power generation facilities are comprised of solar modules, modularized by bonding solar cells to frames. Because solar modules have a structure in which glass plates and other components are bonded to the solar cells, simple disposal is difficult, which poses a major problem for the management of large-scale solar power generation facilities.

[0005] In particular, when disposing of a solar module, the disassembly process of the solar panel (an internal panel consisting of a glass plate and a film-type laminated portion including solar cells laminated on the glass plate) that remains after removing the exterior is a very troublesome issue. Even if the exterior, such as the frame, is properly removed first, it is difficult to cleanly remove the film-type laminated portion bonded to the glass plate, and improper processing can easily cause problems such as damage to the glass plate. Therefore, there is a continuous demand for solutions to these problems. [Prior art documents] [Patent documents]

Furthermore, according to the present invention, thermal deformation of the laminated portion can be induced to cleanly disassemble the glass sheet and the laminated portion, thereby facilitating the recycling of the disassembled parts. Furthermore, the disassembly process can be performed very easily and quickly, improving the overall efficiency of the waste solar module processing process. [Brief explanation of the drawings]

[0021] The advantages and features of the present invention, as well as methods for achieving them, will become clearer with reference to the following detailed embodiments in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, and can be realized in various different forms. The present embodiments are provided solely to complete the disclosure of the present invention and to fully convey the scope of the invention to those skilled in the art to which the present invention pertains. The present invention is defined solely by the claims. The same reference symbols refer to the same elements throughout the specification.

[0022] Hereinafter, the solar panel disassembly device according to the present invention will be described in detail with reference to FIGS.

[0023] FIG. 1 is a perspective view of a solar panel disassembly device according to one embodiment of the present invention, and FIG. 2 is a side view of the solar panel disassembly device of FIG.

[0024] 1 and 2, a solar panel disassembly device 1 according to the present invention includes a support plate 100, a movable scraper module 200 that moves parallel to the support plate 100, movable pressure modules 300a, 300b, 300c, and a curved guide plate 230. A solar panel A to be disassembled is mounted on the support plate 100, and the movable scraper module 200 and the movable pressure modules 300a, 300b, 300c each come into contact with the solar panel A as they move.

[0025] The movable scraper module 200 uses a blade (see 221 in FIG. 6) to scrape off and remove the portion of the solar panel A other than the glass plate A1 (i.e., the laminated film portion A2), and the movable pressure modules 300a, 300b, and 300c uniformly align the portion (laminated film portion A2) in front of the movable scraper module 200. Therefore, the interaction between the movable pressure modules 300a, 300b, and 300c and the movable scraper module 200 allows the solar panel A, in which the glass plate A1 and the laminated film portion A2 other than the glass plate are joined, to be separated into two pieces and disassembled cleanly.

[0026] In particular, a curved guide plate 230 that winds up the separated laminated film portion A2 and stores it inside is formed above the blade 221. The curved guide plate 230 has a roll-shaped structure, and since the film layer (laminated film portion) is wound up in a roll shape and stored in the internal space, processing of the film layer becomes very easy.

[0027] The solar panel disassembly device 1 of the present invention is specifically configured as follows: The solar panel disassembly device 1 is for removing the laminated film part A2 and separating the glass plate A1 from a solar panel A made up of a glass plate A1 and a laminated film part A2 including solar cells laminated on the glass plate, and includes: a support plate 100 that supports the lower part of the solar panel so that the glass plate abuts against the upper surface; a first main body 210 that is connected to guide means and moves parallel to the support plate 100; a first lifting unit 220 that is connected to the first main body 210 so as to be able to rise and fall and rise and fall perpendicular to the moving direction of the first main body 210; and a movable scraper module 200 that is arranged above the support plate 100, is connected to the first lifting unit 220, and has a blade (see 221 in FIG. 6 ) that is changed in height relative to the support plate 100 in accordance with the operation of the first lifting unit 220, and scrapes off the laminated film part A2 with the blade 221 while moving forward parallel to the support plate 100. 8 ), which is connected to the guide means and moves parallel to the support plate 100; a second lifting unit (see 320 in FIG. 8 ) which is connected to the second body 310 so as to be able to rise and fall and moves up and down perpendicular to the direction of movement of the second body 310; and a pressure unit (see 321 in FIG. 8 ) which is arranged above the support plate 100 and connected to the second lifting unit 320 so that its height relative to the support plate 100 changes according to the operation of the second lifting unit 320. The movable pressure modules 300a, 300b, 300c are arranged in front of the movable scraper module 200 in the forward direction and pressurize and align the laminated film portion A2 with the pressure unit 321 in front of the movable scraper module when the movable scraper module 200 moves forward; and a curved guide plate 230 which is made of a curved plate and is arranged above the blade 221 and which winds up and stores the laminated film portion A2 which has been detached from the blade 221.

[0028] In one embodiment of the present invention, the curved guide plate 230 may be wound into a roll shape in which the curved plates constituting the curved guide plate have a gradually decreasing radius of curvature, and a storage space (see 230b in FIG. 4) for storing the laminated film part A2 may be formed in the center. In addition, the curved guide plate 230 has openings (see 230a in FIG. 4) between the curved plates that open downward toward the blade 221, and is wound into a roll shape one or more times so that the storage space is not exposed to the outside.

[0029] In addition, the solar panel disassembly apparatus 1 may further include a gas injection unit (see 250 in Figure 4) that injects gas onto the laminated film portion A2 passing between the blade 221 and the curved guide plate 230 to cool the laminated film portion A2, and the gas injection unit 250 may pressurize the laminated film portion A2 and guide it to the opening 230a of the curved guide plate 230 (see operation in Figure 11).

[0030] In addition, multiple movable pressure modules 300a, 300b, 300c that are detachable from each other can be arranged consecutively in front of the movable scraper module 200 in the forward direction, and each movable pressure module 300a, 300b, 300c can further include a heating section (see 322 in Figures 8 and 9) that heats the outer surface of the laminated film section A2 to induce thermal deformation of the laminated film section A2.

[0031] The system may further include a load cell (see 110 in FIGS. 6 and 7) disposed below the solar panel A at a start position where the blade 221 begins to come into contact with the solar panel A, and a control unit (see 500 in FIGS. 6 and 7) that lowers the first lifting unit 220 at the start position to bring the blade 221 into close contact with the solar panel A, and controls the operation of the first lifting unit 220 based on at least one of the magnitude and amount of fluctuation of the load sensed by the load cell 110 to adjust the position of the blade 221. Hereinafter, the configuration, operation, and effects of the present invention will be described in more detail based on one embodiment of the present invention.

[0032] First, a solar panel A, which is the subject of the present invention, will be briefly described with reference to FIG. 1. The solar panel A may be the portion of a typical solar module remaining after removing exterior components such as a frame (a rod-shaped protective structure attached to the edge of the solar module) and a junction box (a cable connection structure attached to the outside of the laminated film portion, i.e., the back surface of the solar module). The solar panel A is the portion of the solar module where actual power generation occurs and is composed of a laminated film portion A2 containing solar cells and a glass plate A1 supporting the film portion. The solar panel A may have an overall rectangular panel shape, and its cross section may have a layered structure including a glass plate A1 and a laminated film portion A2 containing solar cells laminated on the glass plate A1. The solar panel A may be broadly divided into a glass plate A1 layer and a laminated film portion A2 layer bonded to the glass plate A1. The laminated film portion A2 contains solar cells, and may also include, in addition to the solar cells, encapsulation films and back sheets disposed on both sides of the solar cells. The solar panel disassembly device 1 of the present invention is a device that disassembles such a solar panel A into a glass plate A1 and a laminated film part A2.

[0033] The solar panel disassembly apparatus 1 may include a housing 400 as a support structure. Other components of the present invention may be disposed inside the housing 400. The housing 400 may be formed, for example, by combining a metal frame or metal plates, and may provide a foundation and framework for supporting other components. The housing 400 may be partially open and partially closed to allow objects to enter and exit and to protect the interior. For example, an opening 401 may be formed on one side of the housing 400 through which the solar panel A or the glass plate A1 remaining after disassembly enters and exits, and a door 402 may be formed on the other side. The shape of the housing 400 is not limited and may be variously modified as needed.

[0034] One or more guide means may be disposed in the housing 400. The guide means may guide the movement of the movable scraper module 200 and the movable pressure modules 300a, 300b, and 300c and determine their direction of movement. The forward movement direction, described below, may be parallel to the guide means. For example, the guide means may include a third guide bar 430 disposed at the top of the housing 400, a first guide bar 410 disposed slightly lower or at the same height, and a second guide bar 420 disposed at the bottom of the housing 400 at a position lower than the first guide bar 410 and the third guide bar 430. Each guide bar may be disposed in at least one pair. As shown in the figure, the guide bars are all arranged in the same direction.

[0035] The housing 400 can also be used to form a drive structure that provides power to the movable scraper module 200 and the movable pressure modules 300a, 300b, and 300c. When the drive structure is composed of a combination of components, at least some of them can be located in the housing 400. For example, the drive structure can include a drive shaft 440 disposed across the housing 400 and parallel to the guide means. The drive shaft 440 is coupled to the drive block 213 of the movable scraper module 200 and can form a linear actuator such as a ball screw (in this case, the drive shaft can be threaded, and the drive block can be formed with ball bearings that engage with the threads). A drive motor 450 disposed in the housing 400 can rotate the drive shaft 440 (which can use a power transmission device such as a belt or chain) to move the movable scraper module 200 parallel to the drive shaft 440. The movable pressure modules 300a, 300b, and 300c can move together with the drive force provided to the movable scraper module 200. However, the present invention is not limited to this, and the method of providing power to the movable scraper module 200 and the movable pressure modules 300a, 300b, and 300c can be changed as appropriate.

[0036] The support plate 100 is arranged horizontally inside the housing 400. The support plate 100 has a flat upper surface. The support plate 100 is provided low on the bottom side of the housing 400 and may be located adjacent to the opening 401 described above. Such a support plate 100 supports the lower part of the solar panel A so that the glass plate A1 abuts against the upper surface. That is, the solar panel A is arranged horizontally with the glass plate A1 facing downward and the laminated film portion A2 facing upward, and is mounted on the support plate 100. FIG. 1 shows this state, with the solar panel A mounted on the support plate 100 overlapping the support plate 100.

[0037] A load cell (see 110 in FIGS. 6 and 7 ), which will be described later, may be disposed at one end of the support plate 100. A stopper (see 120 in FIG. 2 ) for fixing the solar panel A may be disposed at the other end of the support plate 100. The movable scraper module 200 can advance while in close contact with the solar panel A from at least one end of the support plate 100 where the load cell 110 is located to the other end of the support plate 100 where the stopper 120 is located (see FIG. 10 ). Therefore, this direction is the forward movement direction of the movable scraper module 200 (the direction of the right-pointing arrow in FIG. 10 ). The movable pressure modules 300a, 300b, and 300c also advance in the same direction while in close contact with the solar panel A, and are positioned in front of the movable scraper module 200 in the forward movement direction (i.e., at a more forward position in the forward movement direction) (see FIG. 10 ). As shown in Fig. 2, the movable scraper module 200 can be retracted to the outside of the support plate 100 before operation, so that the movable pressure modules 300a, 300b, and 300c can be pushed to one end of the support plate 100 and prepared. That is, before starting operation, the movable pressure modules 300a, 300b, and 300c can be moved to just in front of the movable scraper module 200 shown in Fig. 2 and prepared in a state of being in close contact with the movable scraper module 200. Specific operations will be described in detail later.

[0038] 1, the movable scraper module 200 includes a first body 210 connected to a guide means and moving parallel to the support plate 100, a first lifting unit 220 connected to the first body 210 for elevation and moving vertically in a direction perpendicular to the movement of the first body 210, and a blade (see 221 in FIG. 6 ) disposed above the support plate 100 and connected to the first lifting unit 220, the height of which relative to the support plate 100 changes in response to the movement of the first lifting unit 220. The movable scraper module 200 configured in this manner advances parallel to the support plate 100, scraping the laminated film portion A2 from the solar panel A with the blade 221 (see the enlarged view in FIG. 10 ). More specifically, the movable scraper module 200 can use the blade 221 to cut the joint between the glass plate A1 and the laminated film portion A2 of the solar panel A, thereby separating both sides into two parts. The structure and operation of the movable scraper module 200 will now be described in more detail with reference to Figures 3-7.

[0039] Figure 3 is an enlarged view of the movable scraper module of the solar panel disassembly apparatus of Figure 1, Figures 4 and 5 are operational diagrams showing the structure of the curved guide plate and the operation of the pressure roller arranged in the movable scraper module of Figure 3, Figure 6 is an enlarged view showing the movable scraper module of Figure 3 with the curved guide plate and pressure roller removed, and Figure 7 is an operational diagram showing the operation of adjusting the position of the blade arranged in the movable scraper module of Figure 6. The movable scraper modules in Figures 4, 5 and 7 are shown in cross section.

[0040] In Figure 3, the blade (see 221 in Figure 4) is covered by the curved guide plate 230. However, when the curved guide plate 230 is separated, its position can be confirmed as shown in Figure 6. In the following description of the blade 221, please also refer to the exploded view of Figure 6.

[0041] The first body 210 of the movable scraper module 200 is connected to the guide means and moves parallel to the support plate 100. The first body 210 may be a structure formed of, for example, a metal frame, and may support the first lifting unit 220 and the blade 221 connected thereto so that they can be raised and lowered on the guide means. The first body 210 may have various shapes and structures that allow it to move along the guide means. Therefore, it may be modified into various shapes in addition to the shape shown in FIG. 3. A chain-shaped cable guide for use in electrical wiring may also be arranged on the outer surface of the movable scraper module 200.

[0042] The first body 210 applies pressure in the same direction while moving parallel to the support plate (see 100 in FIG. 2) to push the blade (see 221 in FIG. 4) between the glass plate (see A1 in FIG. 1) and the laminated film portion (see A2 in FIG. 1). Therefore, by connecting to at least two pairs of different guide bars, structural stability can be enhanced. For example, the first body 210 may be connected to at least two pairs of guide bars that are parallel to the support plate 100 and spaced apart from each other in the vertical direction, with one pair positioned higher than the blade 221 and the other pair positioned lower than the blade 221.

[0043] The first body 210 may be slidably coupled to the first guide bar (see 410 in FIGS. 1 and 2) via a first slider 211 formed on one side, and may be slidably coupled to the second guide bar (see 420 in FIGS. 1 and 2) via a second slider 212 formed on the other side. As described above, each guide bar may be formed in pairs, and each slider formed on the first body 210 may also be formed in pairs at corresponding positions. In particular, as shown in the figure, the first slider 211 is disposed above the blade 221, and the second slider 212 is disposed below the blade 221. Therefore, the first guide bar 410 and the second guide bar 420 coupled to each slider may form support points for supporting the first body 210 on both the upper and lower sides of the blade 221 (or support points for supporting the blade in a similar manner). Therefore, the blade 221 may be very stably fixed even while the blade 221 moves between the laminated film unit A2 and the glass plate A1.

[0044] The first lifting unit 220 is coupled to the first body 210 so as to be able to move up and down. Referring to FIG. 4 , the blade 221 is disposed above the support plate 100 and connected to the first lifting unit 220, and its height relative to the support plate 100 is changed according to the operation of the first lifting unit 220. That is, the blade 221 is fixed to the first lifting unit 220, and its height is changed together with the first lifting unit 220. The first lifting unit 220 may also be a structure formed of a metal frame or the like, and may be formed in various shapes capable of fixing the blade 221. A first lifting driver 214 that is extendable, for example, vertically (i.e., perpendicular to the horizontally disposed support plate) may be disposed between the first lifting unit 220 and the first body 210, and the height of the first lifting unit 220 and the blade 221 can be changed by extending or retracting the first lifting driver 214. The first lifting driver 214 may be, for example, a linear actuator with a structure in which the lengths of both ends can be changed, and such a linear actuator can be realized in various forms, for example, a ball screw device coupled to a stepping motor, a hydraulic cylinder, etc. If necessary, a first lifting guide 214a (for example, consisting of a vertical guide bar and a slider coupled thereto) that guides vertical movement can be disposed between the first body 210 and the first lifting unit 220 to increase the stability of the lifting operation.

[0045] The blade 221 may be disposed at an appropriate position on the first lifting unit 220. For example, when the entire first lifting unit 220 is positioned above the support plate 100, the blade 221 may be disposed at the lower end of the first lifting unit 220 (see FIG. 4). This structure is shown in the present embodiment. More specifically, the blade 221 may protrude obliquely from the lower end of the first lifting unit 220, and the end may be machined into a pointed shape. The blade 221 may be firmly attached to the first lifting unit 220 and formed to prevent rattle. The blade 221 may be formed of a high-strength metal blade or the like. A temperature adjustment unit 222 that applies heat to the blade 221 to increase the temperature of the blade 221 may be disposed on one side of the blade 221, thereby allowing the blade 221 to scrape off the laminated film portion A2 in a heated state. The temperature adjusting unit 222 may be formed, for example, by a heating wire disposed adjacent to the blade 221, and such a structure can effectively heat the entire blade 221. A heat insulating unit 223 made of a heat insulating material may be disposed where necessary, such as between the temperature adjusting unit 222 and the first lifting driver 214.

[0046] A curved guide plate 230 is disposed above the blade 221. The curved guide plate 230 is made of a curved plate and is disposed above the blade 221 to wind up and store the laminated film portion detached from the blade 221. The curved guide plate 230 and its related structure will be described in more detail below with reference to Figures 4 and 5.

[0047] The curved guide plate 230 has a structure for immediately collecting the laminated film portion A2 discharged above the blade 221 when the blade 221 cuts the laminated film portion A2 of the solar panel A. As shown in Figures 3 to 5, the curved guide plate 230 is made of a curved plate, and the curved plate is formed by bending in an arc shape. In particular, the curved guide plate 230 may be formed by winding the curved plate into a roll shape in which the radius of curvature gradually decreases.

[0048] As a result, the curved guide plate 230 has an internal storage space 230b for storing the laminated film portion. The curved guide plate 230 is formed by rolling up curved plates in a roll shape, with the curved plates spaced apart from one another. Therefore, a passage is formed inside the curved guide plate 230, bending along the curved plates. As shown in Figure 4, an opening 230a is formed at the entrance of the passage, and a storage space 230b is formed in the center of the interior that communicates with the passage.

[0049] The curved guide plate 230 has openings 230a between the curved plates that open downward toward the blade 221 disposed below the curved guide plate 230. Therefore, the laminated film portion that is cut by the blade 221 and discharged upward can be drawn into the interior through the downward-opening openings 230a. The curved guide plate 230 may be wound one or more times in the form of a roll as shown in the figure, so that the internal storage space 230b is not exposed to the outside. Here, "not exposed" means that it is not exposed at least in the direction of the openings 230a.

[0050] The curved guide plate 230 may be wound into such a roll shape and extend horizontally. For example, as shown in FIG. 3, the curved guide plate 230 may extend horizontally to a length corresponding to the length of the blade 221. The curved guide plate 230 may be formed, for example, from a curved metal plate, but may also be formed from other materials as needed. The curved guide plate 230 may be formed from various materials that can be processed into a roll shape.

[0051] The curved guide plate 230 may be fixed to the movable scraper module 200. Preferably, the curved guide plate 230 may be disposed on one side of the first lifting unit 220 above the blade 221. The curved guide plate 230 is installed such that the opening 230a opens downward toward the blade 221, and the specific position, roll size (or diameter), curvature radius, etc. may be adjusted as appropriate. The curved guide plate 230 may be fixed using various types of fixing structures, and may be attached by a method such as screw connection. The method of attaching the curved guide plate 230 is not particularly limited. If necessary, the curved guide plate 230 may be formed to be detachable.

[0052] A pressure roller 240 is disposed in front of the blade 221. The pressure roller 240 presses the laminated film portion between the blade 221 and the movable pressure module (see 300a, 300b, and 300c in FIG. 1) to adhere the laminated film portion to the glass plate so that it does not lift up. The pressure roller 240 is connected to, for example, a support base 241 and can be movably disposed on one side of the movable scraper module 200.

[0053] An elevation shaft 242 may be formed at the end of the support base 241 that supports the pressure roller 240, rotatably fixing the support base 241 to the movable scraper module 200. The elevation shaft 242 is supported by a compression spring (not shown) that is compressed in the vertical direction, and can elastically move up and down. This allows the pressure roller 240 to rotate around the elevation shaft 242, and the height can also be adjusted in accordance with the elevation of the elevation shaft 242.

[0054] Therefore, for example, when the first lifting unit 220 descends as shown in Fig. 4, the lifting shaft 242 ascends in the opposite direction as shown in Fig. 5, and the position of the pressure roller 240 can be adjusted accordingly. In addition, the pressure roller 240 can rotate about the lifting shaft 242, and therefore can press the laminated film unit A2 while rotating to one side in response to the elevation of the first lifting unit 220. For example, a torsion spring (not shown) that applies torque to the lifting shaft 242 so as to press the pressure roller 240 toward the solar panel can be applied to the lifting shaft 242. Using such a pressure roller 240, the laminated film unit A2 can be pressed between the movable pressure modules 300a, 300b, 300c and the blade 221 to prevent it from lifting up.

[0055] A gas injection unit 250 may be formed between the blade 221 and the curved guide plate 230. Referring to Fig. 4, the gas injection unit 250 may be formed above the blade 221 of the first lifting unit 220. The gas injection unit 250 includes a structure capable of injecting pressurized gas B and may also include a temperature control structure, if necessary. The gas injection unit 250 can inject gas onto the laminated film portion passing between the blade 221 and the curved guide plate 230 to cool the laminated film portion.

[0056] 4 illustrates an example of the structure of the gas injection unit 250. The gas injection unit 250 may be formed as a nozzle-like structure that passes pressurized gas B and injects it toward the blade 221. A supply structure (not shown) that supplies pressurized gas B may be connected to one side of the gas injection unit 250, and this supply structure may include, for example, a gas supply pipe, a compressed gas supply unit (e.g., a pump), etc. The gas injection unit 250 may inject gas cooled by the supply structure. However, if necessary, a temperature control structure (not shown) capable of cooling the gas may be included therein. The gas supply structure, etc. may be appropriately arranged using the internal space of the housing, etc.

[0057] That is, by cooling the laminated film portion heated by the heating unit (see 322 in FIG. 9 ), which will be described later, using gas injected from the gas injection unit 250, the laminated film portion can be prevented from relaxing and regain its elasticity. Preferably, the gas injection unit 250 can inject gas at a temperature below the melting point of the laminated film portion. By adjusting the temperature of the laminated film portion using the gas injection unit 250 in this manner, the laminated film portion is discharged upward while maintaining a moderate degree of elasticity, which allows it to be more easily inserted into the curved guide plate 230 above the blade 221 (see the operation in FIG. 11 ).

[0058] Furthermore, the gas injection unit 250 can pressurize the laminated film portion with the injected pressurized gas B as shown in FIG. 4 and guide it to the opening 230a of the curved guide plate 230 (see the operation in FIG. 11). That is, the gas injection unit 250 can cool the laminated film portion to a temperature below its melting point to impart elasticity, while also adjusting the bending direction of the laminated film portion using the gas pressure. This can be achieved, for example, by adjusting the injection pressure and injection direction of the pressurized gas B. By using the gas injection unit 250 with this function, the laminated film portion detached from the blade 221 can be more effectively inserted into the curved guide plate 230 through the opening 230a of the curved guide plate 230.

[0059] A slit (see 251 in FIG. 6) may be formed at the end of the gas injection unit 250, extending parallel to the blade 221. The slit 251 may be arranged elongated in the lateral direction of the extension of the blade 221. The gas injection unit 250 may inject pressurized gas through the slit 251 into the entire space corresponding to the extension length of the blade 221. By using such a structure, the laminated film unit can be wound into a roll and collected. Specific operations will be described in detail later.

[0060] The blade position adjustment method will be described in detail below with reference to Figures 6 and 7. Figure 6 shows the blade with the curved guide plate and pressure roller removed. For ease of explanation, the curved guide plate and pressure roller are temporarily omitted here.

[0061] The height of the blade 221 can be adjusted with high precision using a load cell 110 that detects the load. Specifically, the load cell 110 is disposed under the solar panel (see A in FIG. 7) at a start position where the blade 221 begins to contact the solar panel A. The control unit 500 may also be provided, together with the load cell 110, to lower the first lifting unit 220 from the start position to bring the blade 221 into close contact with the solar panel A, and to control the operation of the first lifting unit 220 based on at least one of the magnitude and fluctuation of the load detected by the load cell 110 to adjust the position of the blade 221. The control unit 500 may be connected to the load cell 110 to exchange electrical signals, and may also be connected to the first lifting driver 214 described above to exchange electrical signals. Such connections include both wired and wireless connections. The control unit 500 may be configured, for example, as a computer device including a central processing unit (CPU), and such a computer device may include a programmable logic controller (PLC) or the like. The control unit 500 is provided in a suitable position on the housing.

[0062] The start position is the position where the blade 221 begins to contact the solar panel A, and may therefore be the same as the position where the disassembly process begins. Referring to FIG. 7 , the start position may be, for example, a position where the blade 221 abuts against the edge of the solar panel A or a position where the blade 221 slightly overlaps the edge. The start position is a position where the blade 221 can press the solar panel A when it descends, and may be the outermost position of the solar panel A. The start position may be arbitrarily set as a position for starting the disassembly process and may be changed as needed. However, in either case, the blade 221 can contact the solar panel A at the start position. The load cell 110 is disposed below the solar panel A at this start position. The load cell 110 may be located at the same height as the support plate 100 and provided at one end of the support plate 100. For example, a space may be formed by partially cutting a portion of the support plate 100, and the load cell 110 may be disposed in the space so as to abut against the solar panel A.

[0063] Therefore, the load cell 110 contacts the bottom of the solar panel A and can immediately detect the load applied from the top of the solar panel A and its changes. The operation of adjusting the position of the blade 221 using the load cell 110 and the control unit 500 will be described in more detail with reference to FIG. 7. First, the movable scraper module 200 can move to the start position along the aforementioned guide means. FIG. 7 illustrates the movable scraper module 200 in the start position. However, this operation is not essential and may not be necessary depending on the situation. For example, if the retracted position (e.g., the position in FIG. 2) is different from the start position (i.e., the blade does not immediately come into contact with the solar panel even when lowered), this preliminary operation may be necessary. However, if the retracted position is appropriate and is the same as the start position, the blade 221 can be immediately lowered to contact the solar panel A, and therefore no separate preliminary operation is necessary. For example, such preparatory operations may or may not be performed by appropriately considering various situations, such as when there is partial variation in the size of the solar panel A or when the movable range of the movable scraper module 200 is relatively wide.

[0064] 7, the control unit 500 lowers the first lifting unit 220 from the start position because the blade 221 is ready to come into contact with one end of the solar panel A. The control unit 500 can lower the first lifting unit 220 by extending the first lifting driver 214. Therefore, the blade 221 connected to the first lifting unit 220 presses against the solar panel A, which appears as a change in the load value sensed by the load cell 110. The sensed load is immediately transmitted to the control unit 500.

[0065] The control unit 500 controls the operation of the first lifting unit 220 based on the transmitted load value. The control unit 500 can change the position of the first lifting unit 220 by transmitting a control signal to the first lifting driver 214 in response to the load value. In particular, the control unit 500 controls the operation of the first lifting unit 220 based on at least one of the magnitude and fluctuation of the load sensed by the load cell 110 to adjust the position of the blade 221. The blade 221 first contacts the outer surface of the laminated film unit A2 and gradually approaches the glass sheet A1 as it descends. The blade 221 easily passes through the section of the laminated film unit A2 that is low in density and easily deforms, but encounters increasing resistance as it approaches the glass sheet A1. Therefore, as the blade 221 approaches the glass sheet A1, the load sensed by the load cell 110 increases rapidly, and the amount of load fluctuation also increases rapidly. Therefore, for example, when the load sensed by the load cell 110 reaches a set value, or when the amount of change in the load (e.g., per unit time) reaches a set value, the control unit 500 can stop the descent of the first lifting unit 220 and position the blade 221 at the corresponding position.

[0066] The control unit 500 may include, for example, a control program that executes the above-described control operations through corresponding calculations. The control unit 500 can execute the above-described control by loading such a control program. By appropriately setting an upper limit for at least one of the magnitude and fluctuation of the load, the blade 221 can be positioned with high precision on the surface of the glass plate A1. For example, experiments on a large number of solar panels A can be conducted in advance, data can be accumulated, and appropriate setting values ​​can be derived from the accumulated data. It is also possible to adaptively update appropriate setting values ​​using data obtained through repeated operations. By using such control, the end of the blade 221 can be stopped at a position substantially elevated by the thickness C of the glass plate A1 from the support plate 100, as shown in FIG. 7.

[0067] The movable scraper module 200 adjusts the height of the blade 221 at the start position in this manner, and then immediately advances parallel to the support plate 100 to cut the laminated film portion A2. The height adjustment and advancement of the blade 221 can be performed continuously without interruption. Furthermore, even if a preliminary operation of moving from the retracted position described above to the start position shown in FIG. 7 is required, this operation can be performed continuously. Therefore, the movable scraper module 200 can perform the operations of lowering the height of the blade 221 to the surface of the glass sheet A1 while essentially moving, and scraping the laminated film portion A2 while advancing, as a single sequence. The movable scraper module 200 can be operated in this manner. The operation of the entire apparatus, including this, will be described in more detail below.

[0068] FIG. 8 is an enlarged view of a movable pressure module in the solar panel disassembly apparatus of FIG. 1, and FIG. 9 is a cross-sectional view showing the internal structure of the movable pressure module of FIG.

[0069] The movable pressure modules 300a, 300b, and 300c will be described below with reference to Figures 1, 2, 8, and 9. First, the overall arrangement of the movable pressure modules 300a, 300b, and 300c will be described as follows. The movable pressure modules 300a, 300b, and 300c include a second body 310 connected to a guide means and moving parallel to the support plate 100, a second lifting unit (see 320 in Figure 8) connected to the second body 310 so as to be able to move up and down and move up and down perpendicular to the moving direction of the second body 310, and a pressure unit (see 321 in Figures 8 and 9) disposed above the support plate 100, connected to the second lifting unit 320, and whose height relative to the support plate 100 is changed in accordance with the operation of the second lifting unit 320. The movable pressure modules 300a, 300b, and 300c are disposed forward in the forward direction of the movable scraper module 200 (the direction of the arrow on the right side in Figure 10). With this configuration, when the movable scraper module 200 advances, the pressure unit 321 can press and align the laminated film unit (see A2 in FIG. 1) in front of the movable scraper module 200. Specifically, the movable pressure modules 300a, 300b, and 300c are connected to the third guide bar 430 of the aforementioned guide means and can be moved. As shown in the figure, multiple detachable pressure modules can be arranged consecutively in front of the movable scraper module 200 in the forward direction.

[0070] The multiple movable pressure modules 300a, 300b, and 300c are substantially identical in that they each include a second body 310, a second lifting unit 320, and a pressure unit (see 321 in FIGS. 8 and 9). They are also substantially identical in that they each include a heating unit (see 322 in FIGS. 6 and 7) that heats the outer surface of the laminated film unit A2 to induce thermal deformation of the laminated film unit A2. However, there may be a slight difference in that any one of the movable pressure modules 300a closest to the movable scraper module 200 includes a distance control rod (see 313 in FIG. 8) to adjust the distance between the movable scraper module 200 and the movable pressure module 300a. For example, even if a movable pressure module is configured independently, the corresponding movable pressure module may include the distance control rod 313.

[0071] The movable pressure modules 300a, 300b, and 300c may be configured in a manner not connected to the drive shaft 440, and therefore may not receive driving force directly from the drive structure. The movable pressure modules 300a, 300b, and 300c are in contact with the movable scraper module 200 and may be pushed and moved by the movable scraper module 200 as the movable scraper module 200 advances. Therefore, the forward movements of the movable scraper module 200 and the movable pressure modules 300a, 300b, and 300c are substantially synchronized. However, this is not a limitation, and driving force may also be supplied to the movable pressure modules 300a, 300b, and 300c as needed. Although not shown in the drawings, the movable pressure modules 300a, 300b, and 300c may be connected to each other by a chain or the like, thereby allowing them to move in unison even when moving in the direction opposite to the forward direction. As described above, before starting operation, the movable scraper module 200 can be completely retracted to the position shown in Fig. 2, and the movable pressure modules 300a, 300b, and 300c can be moved to just in front of the movable scraper module 200 shown in Fig. 2 and prepared in a state where they are in close contact with the movable scraper module 200. Thereafter, as the movable scraper module 200 advances, it can push the movable pressure modules 300a, 300b, and 300c forward together.

[0072] The structural features of the movable pressure module will be described in more detail with reference to Figures 8 and 9. Since all of the substantial features of the movable pressure module are included in the movable pressure module 300a, which is the module that is closest to the movable scraper module among the multiple movable pressure modules (see 300a, 300b, and 300c in Figures 1 and 2), the description of the specific structure will be based on the movable pressure module 300a. It can be understood that the other movable pressure modules (300b and 300c in Figures 1 and 2) include similar components except for the spacing control rod 313.

[0073] The second body 310 of the movable pressure module 300a may be a structure formed of, for example, a metal frame. The second body 310 may support the second lifting unit 320 and the pressure unit 321 connected to the second lifting unit 320 on a guide means so that they can be raised and lowered. The second body 310 may have various shapes and structures that allow it to move along the guide means, and therefore may be modified into various shapes without being limited to the shape shown in FIG. 8. A chain-shaped cable guide, etc., for use in electrical wiring, etc., may be disposed on the outer surface of the movable pressure module 300a. The second body 310 is slidably coupled to the third guide bar (see 430 in FIGS. 1 and 2) by a third slider 311 formed on one side. Since the guide bars are disposed in pairs, the third sliders 311 may also be disposed in pairs at corresponding positions. As described above, the third guide bar 430 is located at the top end of the housing 400, and can be coupled with the third slider 311 to form a support point at the top end of the second body 310. This structure is advantageous in that the pressure unit 321 can be lowered to apply pressure to and align the laminated film unit (see A2 in FIG. 1).

[0074] The second lifting unit 320 is coupled to the second main body 310 so as to be movable up and down. The pressure unit 321 is disposed above the support plate (see 100 in FIGS. 1 and 2 ) and is connected to the second lifting unit 320, so that its height relative to the support plate 100 is changed according to the operation of the second lifting unit 320. That is, the pressure unit 321 is fixed to the second lifting unit 320, and its height is changed together with the second lifting unit 320. The second lifting unit 320 may also be a structure formed of a metal frame or the like, and may be formed in various shapes to which the pressure unit 321 can be fixed. A second lifting driver 312 that is extendable, for example, vertically (i.e., perpendicular to the horizontally disposed support plate) may be disposed between the second lifting unit 320 and the second main body 310, and the heights of the second lifting unit 320 and the pressure unit 321 can be changed by extending or retracting the second lifting driver 312. The second lifting driver 312 is implemented as, for example, a linear actuator with variable lengths at both ends. Such a linear actuator may be realized in various forms, such as a hydraulic cylinder. If necessary, a second lifting guide 312a (for example, a vertical guide bar and a slider connected thereto) for guiding vertical movement may be disposed between the second body 310 and the second lifting unit 320 to improve the stability of the lifting operation. The second lifting guide has a guide bar connected to the second lifting unit and a slider fixed to the second body, so that the entire guide bar can rise and fall in response to the movement of the second lifting unit.

[0075] A buffer portion 314 may be disposed in the forward direction of the second body 310 as needed. The buffer portion 314 is used to adjust the spacing between multiple movable pressure modules. Therefore, a specific movable pressure module located at the outermost position in the forward direction (e.g., 300c in FIGS. 1 and 2) may not require a buffer portion 314. The position of the buffer portion 314 can be adjusted as needed, thereby supporting the appropriate positions of the other movable pressure modules. The buffer portion 314 does not need to support the outermost positions of the other movable pressure modules, but can also support the inner frame of the movable pressure module. By selecting the position, the spacing between the movable pressure modules can be adjusted in various ways. Furthermore, the length of the buffer portion 314 can be extended or shortened as needed, allowing multiple movable pressure modules to advance while maintaining appropriate spacing.

[0076] The pressure unit 321 may be disposed at an appropriate position of the second lifting unit 320. For example, if the entire second lifting unit 320 is positioned above the support plate 100, the pressure unit 321 may be disposed as a planar structure at the lower end of the second lifting unit 320. The pressure unit 321 contacts the laminated film unit A2 at the front in the forward direction before the blade (see 221 in FIG. 6 ) and applies pressure to align the laminated film unit A2. As shown in FIG. 9 , the pressure unit 321 may include a plurality of support rollers 321a that are spaced apart and make rolling contact with the outer surface of the laminated film unit A2. The plurality of support rollers 321a may be used to apply pressure to the surface of the laminated film unit A2 while moving. However, this is not limited thereto, and the pressure unit 321 may be modified into other shapes that can apply pressure to the surface of the laminated film unit A2 and align it.

[0077] The movable pressure module 300a may include a heating unit 322 that heats the outer surface of the laminated film unit A2 to induce thermal deformation of the laminated film unit A2. That is, by applying pressure and heat simultaneously using the pressure unit 321, the laminated film unit A2 can be induced to at least partially deform. Even if excessive thermal deformation is not apparent due to the pressure applied by the pressure unit 321, the induced deformation is sufficient to weaken the bond between the laminated film unit A2 and the glass plate (see A1 in FIG. 1). That is, before cutting with the blade 221, heating with the movable pressure module 300a can make the laminated film unit A2 easier to peel. Furthermore, by applying pressure and aligning with the pressure unit 321, no obstacles arise when the blade 221 enters.

[0078] Referring to FIG. 7, the pressure unit 321 includes a plurality of support rollers 321a spaced apart from one another and in rolling contact with the outer surface of the laminated film unit A2. The heating unit 322 may be formed as a heater inside the pressure unit 321 that radiates heat into the spaces between the support rollers 321a. That is, the heating unit 322 may be arranged overlapping the pressure unit 321 to simultaneously apply pressure and heat to substantially the same surface. The heater forming the heating unit 322 may emit, for example, at least one of infrared rays and hot air. Heat can be supplied by various methods, including, for example, a radiant heating method that radiates heat rays such as infrared rays into the spaces between the support rollers 321a, or a convective heating method that supplies heated fluid to heat the entire surrounding area. However, the heat supply method is not limited thereto, and other heating methods may be freely used if possible.

[0079] A gap control rod 313 may be disposed in the movable pressure module 300a. The gap control rod 313 is interposed between the movable scraper module (see 200 in FIGS. 1 to 3 ) and the movable pressure module 300a to adjust the gap between the blade 221 and the pressure member 321. The gap can be appropriately set as needed. Even if a gap exists between the blade 221 and the pressure member 321, the aforementioned pressure roller (see 240 in FIGS. 4 and 5 ) can be used to press the middle portion to continuously pressurize the laminated film portion, thereby preventing the laminated film portion from lifting up. As shown in FIGS. 8 and 9 , the gap control rod 313 protrudes from the side of the second body 310 facing the movable scraper module 200, and a buffer structure may be formed at the end. The length of the gap control rod 313 can also be adjusted as needed. The gap control rod 313 does not necessarily have to be disposed in the movable pressure module 300a; in other embodiments, it can be disposed on the movable scraper module 200 side. The solar panel disassembly operation of the present invention will be described in more detail below with reference to FIGS.

[0080] Figure 10 is a diagram showing the solar panel disassembly operation by the solar panel disassembly device of Figure 1, and Figure 11 is a diagram showing in more detail the operation of the curved guide plate during the disassembly operation of Figure 10. Figure 12 is a diagram showing the operation after the solar panel has been disassembled by the solar panel disassembly device of Figure 1. For reference, in order to more clearly show the disassembly process, all of the main components within section a (see Figures 10 and 12) where the solar panel is located are shown in cross section.

[0081] With the above configuration, the solar panel disassembly device 1 operates as follows to automatically disassemble the solar panel A. The disassembly operation will be explained with reference to FIG. 10 . The movable scraper module 200 lowers the blade 221 at the start position (as described above, see FIG. 7 ) to contact the solar panel A, and then moves forward. As described above, the blade 221 can be fixed at the start position with its edge aligned with the surface of the glass plate A1 under the control of the load cell (see 110 in FIGS. 6 and 7 ) and the control unit (see 500 in FIGS. 6 and 7 ). That is, the blade 221 can cut the laminated film portion A2 with its edge accurately positioned at the joining position between the glass plate A1 and the laminated film portion A2.

[0082] As described above, if the starting position is the same as the retracted position of the movable scraper module 200, the movable scraper module 200 immediately advances while lowering the blade 221. However, depending on the situation, there may be a difference between the retracted position and the starting position. In that case, as described above, a preliminary operation in which the movable scraper module 200 moves slightly from the retracted position to the starting position may be performed. This may vary depending on the situation. Furthermore, the movable pressure modules 300a, 300b, and 300c are prepared in a state in which they are in close contact with the retracted movable scraper module 200 before the movable scraper module 200 operates. At this time, the second lifting unit 320 may automatically descend and abut against the laminated film unit A2 (for example, this can be automatically operated by providing a sensor or the like below). Thereafter, the movable pressure modules 300a, 300b, 300c are pushed and move together with the movable scraper module 200 as it moves (if no driving force is applied to the movable pressure modules individually, the movable pressure modules may be prepared manually, but by applying an appropriate driving structure to the movable pressure modules, any number of similar operations can be performed automatically).

[0083] FIG. 10 illustrates the corresponding forward movement. As shown in FIG. 10, the movable scraper module 200 and the movable pressure modules 300a, 300b, and 300c move together in close contact with each other during the forward movement. When in close contact, the distance between the blade 221 and the pressure unit (see 321 in FIG. 9) can be adjusted by the aforementioned distance control rod 313. The buffer unit 314 supports the inner frame of the movable pressure module and can reduce the distance between the movable pressure modules. As described above, the movable pressure modules 300a, 300b, and 300c press and align the laminated film unit A2 in front of the movable scraper module 200 with the pressure unit 321, and simultaneously induce thermal deformation with the heating unit 322. As a result, the laminated film unit A2 is aligned flat and in contact with the blade 221, with its bond to the glass sheet A1 weakened. The blade 221 is heated by the temperature adjustment unit 222 and is in a state of elevated temperature, which allows it to more easily enter between the laminated film part A2 and the glass plate A1. Therefore, as shown in the enlarged view of Fig. 10, the laminated film part A2 can be cut (or scraped) from the glass plate A1, allowing for clean disassembly.

[0084] At this time, the cut laminated film portion A2 is wound up in a roll and inserted into the curved guide plate 230 arranged above the blade 221. That is, the laminated film portion A2 separated from the glass sheet A1 and discharged above the blade 221 can be immediately collected by being accommodated in the roll-shaped curved guide plate 230 located above the blade 221.

[0085] Although the laminated film portion A2 has elasticity, its plasticity has been increased by heat, so that it can be guided toward the curved guide plate 230 by appropriately changing its direction. In particular, the gas injection unit 250 described above can inject pressurized gas B onto the laminated film portion A2 between the blade 221 and the curved guide plate 230 to cool it (increase its elasticity) and at the same time pressurize it, thereby changing its direction toward the opening 230a. As described above, the pressure of the injected gas can also be appropriately adjusted.

[0086] 11, the process of recovering the laminated film part A2 using the curved guide plate 230 is shown in more detail. Each step is shown separately for the purpose of explanation, but in reality, the steps proceed consecutively.

[0087] 11(a), the end of laminated film portion A2 cut by blade 221 rises above blade 221. Before contacting blade 221, laminated film portion A2 is pressed by pressure roller 240 in front of blade 221 and is therefore in close contact with glass plate A1. However, after contacting blade 221 and being cut, laminated film portion A2 is pushed by blade 221 and rises above blade 221.

[0088] At this time, the gas injection unit 250 injects pressurized gas B, which cools the laminated film portion A2 to below its melting point. The pressurized gas B cools and pressurizes the laminated film portion A2 at the same time. Therefore, the gas pressure changes the direction toward the opening 230a. As shown in the figure, applying gas pressure toward the opening 230a of the curved guide plate 230 arranged above the blade 221 effectively guides the entry of the laminated film portion A2.

[0089] 11(b) and (c), the cut laminated film portion A2 is inserted into the inside of the opening 230a of the curved guide plate 230. The laminated film portion A2 naturally enters the opening 230a side, which is the entrance, while elastically contacting the roll-shaped surface of the curved guide plate 230. In addition, the laminated film portion A2 is also pressed toward the opening 230a by the pressurizing action of the gas injection portion 250, so that the laminated film portion A2 easily enters the inside of the opening 230a, which is the entrance of the curved guide plate 230.

[0090] As shown in Figure 11(d), laminated film portion A2 that has entered opening 230a is wound into a roll shape inside curved guide plate 230 again along the roll-shaped structure of curved guide plate 230. As blade 221 advances, laminated film portion A2 continues to be cut open and inserted into curved guide plate 230, and laminated film portion A2 is moved along the curved surface by the pressure applied to the inside of curved guide plate 230 and deformed into a roll shape. In this manner, laminated film portion A2 can be wound into a roll shape and collected inside storage space 230b inside curved guide plate 230, as shown in Figure 11(e).

[0091] The diameter of the curved guide plate 230 can be adjusted as needed, so that the entire laminated film portion A2 cut into the storage space 230b of the curved guide plate 230 can be wound up and collected. Furthermore, since the storage space 230b inside the curved guide plate 230 has a roll-shaped structure, it is not substantially exposed to the outside, so there is no risk of the laminated film portion A2 inserted inside falling out. In this way, the roll-shaped structure of the curved guide plate 230 allows the laminated film portion A2 to be wound up into a roll and easily collected.

[0092] This operation continues until the blade 221 reaches the other end of the solar panel A, thereby enabling the entire laminated film portion A2 to be cleanly peeled off and removed from the solar panel A. As the forward movement of the movable scraper module 200 progresses, the laminated film portion A2 is cleanly removed from the solar panel A, so that substantially only the glass plate A1 remains behind the blade 221.

[0093] When the forward movement is completed and the laminated film portion A2 is completely separated, only the glass plate A1 remains on the entire support plate 100, as shown in Figure 12. After completing the forward movement, the movable scraper module 200 moves back in the opposite direction to retreat. At the same time, the curved guide plate 230, which has collected the laminated film portion A2 separated from the blade 221, also rises together with the first lifting unit 220. Note that the movable pressure modules 300a, 300b, and 300c may continue to move forward due to inertia, and the second lifting unit 320 may rise as it separates from the support plate 100.

[0094] The laminated film portion A2 inside the curved guide plate 230 can be wound into a roll to form a laminated film portion coil A2-1. The laminated film portion coil A2-1 inserted into the accommodation space inside the curved guide plate 230 can be removed from one side of the curved guide plate 230 after the movable scraper module 200 returns to its original position. Alternatively, the entire curved guide plate 230 can be configured to be detachable so that it can be separated together with the curved guide plate 230. In this way, the laminated film portion can be cut open, separated, and wound into a roll for easy collection.

[0095] Therefore, the solar panel (see A in FIG. 8) can be very easily disassembled into the glass plate A1 and the laminated film coil A2-1. In particular, as described above, the height of the blade 221 is automatically adjusted, and it is positioned very accurately at the joining position between the laminated film and the glass plate, allowing for very clean disassembly with almost no by-products, and the roll-shaped structure of the curved guide plate 230 also makes it possible to easily recover the laminated film. In this way, the solar panel disassembly device 1 of the present invention allows for simple and accurate disassembly of solar panels.

[0096] Although the embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art will understand that the present invention can be embodied in other specific forms without changing the technical spirit or essential features of the present invention. Therefore, it should be understood that the above-described embodiments are illustrative in all respects and are not limiting. [Industrial Applicability]

[0097] This solar panel dismantling device has high applicability in the renewable energy industry, particularly in recycling processes. It can efficiently separate the glass and film components of used solar panels, enabling waste reduction and material recovery. This improves sustainability and cost efficiency in solar panel manufacturing and waste management, making it a valuable tool for recycling facilities and manufacturers seeking to reduce environmental impact and realize a circular economy.
