Description

Technical Field

[0001] This invention relates to the field of textile processing technology, and in particular to a high-down two-box machine with roller-type negative pressure and its down processing method. Background Technology

[0002] In the production of textiles, home textiles, and down products, raw materials often contain varying degrees of dust, debris, and other non-down components. The presence of these impurities directly affects the fluffiness, cleanliness, and quality stability of the final product. Therefore, in the initial processing stage of raw materials, multiple cleaning and screening processes are required using mechanical separation and dust removal equipment to remove entrained materials and improve the purity of the down. The industry commonly uses single-chamber or simple double-chamber separators, which use fans to create negative pressure airflow to suck away the down dust, followed by simple collection and treatment. However, these types of equipment often suffer from insufficient separation efficiency, poor negative pressure stability, easy clogging, difficulty in recycling fine down dust, and high energy consumption, resulting in limited production continuity, significant raw material waste, and a working environment susceptible to secondary pollution.

[0003] Chinese patent discloses a down separation device for processing down products (Publication No.: CN 113019911 A), which includes a shell, a storage chamber located in the middle of the shell, a coarse separation chamber in the upper part of the shell, and a fine separation chamber in the bottom of the shell. The coarse separation chamber is equipped with a suction fan extending into the storage chamber. The interior of the coarse separation chamber is equipped with a coarse separation component for separating coarse fragments. The lower sides of the coarse separation chamber are equipped with coarse separation outlets that cooperate with the coarse separation component. The upper side of the coarse separation chamber is equipped with a conveying fan that connects to the upper side of the fine separation chamber. However, this down separation device has problems such as insufficient separation efficiency, poor negative pressure stability, easy clogging, difficulty in recycling fine down dust, and high energy consumption, which leads to limited production continuity, significant waste of raw materials, and the working environment is easily subject to secondary pollution. Therefore, there is a need for a high-down two-chamber machine with roller-type negative pressure and its down processing method. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of poor negative pressure stability, easy clogging, insufficient separation efficiency, low resource recovery rate and high energy consumption of existing high-down separation equipment, and to propose a high-down two-chamber machine with drum-type negative pressure and its down processing method.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: A high-density two-compartment dust collector with roller-type negative pressure, comprising a two-compartment main body, characterized in that: the two-compartment main body includes a first compartment, a second compartment is located on one side of the bottom of the first compartment, and a negative pressure integrated device is installed inside the second compartment. The negative pressure dust collection device includes a negative pressure roller unit and a dust collection unit. A cleaning execution component is located on one side of the negative pressure roller unit, and a lint inlet pipe is located on one side of the first compartment. The other end of the lint inlet pipe is connected to a lint-adding machine. Through the combination of the two-compartment structure and the negative pressure integrated device, the equipment can process raw materials in different working stages, improving separation efficiency. The negative pressure roller and the dust collection unit work together to effectively capture and concentrate lint, reducing scattering. The cleaning execution component can clean the roller in a timely manner, avoiding blockage and suction reduction, maintaining continuous and stable dust removal performance. The lint inlet pipe is directly connected to the lint-adding machine, ensuring continuous and smooth raw material conveying and improving the degree of production automation.

[0006] Preferably, the negative pressure roller unit includes a drive roller covered with a 12-mesh stainless steel screen for isolating down. One end of the drive roller is connected to a roller belt and a roller main shaft that is associated with and cooperates with the roller belt. One end of the roller main shaft is connected to a roller motor. The dust collection unit includes a suction duct. One bottom end of the suction duct is associated with the drive roller, and one top end of the suction duct penetrates the outer wall of the two-compartment box and is connected to a main fan. One end of the main fan is connected to a dust box, and one bottom end of the dust box is connected to a dust exhaust pipe. One bottom end of the dust exhaust pipe is connected to a dust collection bag. The drive roller rotates under the drive of the motor, forming a stable negative pressure zone, which allows down to be efficiently sucked in. The layout of the suction duct concentrates the dust-laden airflow into the main fan, improving the suction efficiency. The combination of the main fan, dust box, dust exhaust pipe, and dust collection bag achieves air purification and sealed dust collection, preventing secondary pollution, improving the working environment, and reducing cleaning difficulty.

[0007] Preferably, the drive roller includes a cylindrical body and flanges at both ends. The flanges are welded from iron square tubing and iron plates. The cross-sectional dimensions of the iron square tubing are 30mm × 30mm, and the thickness of the iron plates is 5~7mm. The center hole of the flange is used to mount the roller spindle, and the diameter of the roller spindle is φ140~145mm. The robust flange structure enhances the overall rigidity and durability of the roller, enabling it to withstand long-term high-speed operation without easily deforming. The precise fit between the spindle and the flange ensures transmission stability, reduces vibration and noise, extends the roller's service life, and lowers maintenance frequency.

[0008] Preferably, the cylindrical body has negative pressure ports at both ends for introducing negative pressure airflow, and these ports are connected to the interior of the cylinder. The interior of the cylindrical body has a mesh structure composed of multiple square grids. The bidirectional air intake design of the negative pressure ports makes the negative pressure distribution inside the cylinder more uniform, improving the adsorption efficiency of lint. The mesh internal structure increases airflow channels, making it easier for lint to be carried away and reducing residue. This design enhances the separation effect while maintaining the air permeability of the roller surface, avoiding suction attenuation due to clogging.

[0009] Preferably, a waste heat recovery system is provided on one side of the main fan. This system includes a finned housing, which is composed of an upper air inlet, a middle finned heat exchange module, and a lower air outlet. The lower air outlet is connected to the inlet tube. The waste heat recovery system utilizes the hot air discharged from the main fan to preheat the raw materials inside the inlet tube, reducing agglomeration or static electricity caused by low temperatures and improving subsequent processing quality. Simultaneously, this heat reuse reduces overall energy consumption, making the equipment more economical and environmentally friendly.

[0010] Preferably, the ash collection bag is equipped with a waste wool recycling system on one side. This system includes a cyclone separator and a humidification section. The cyclone separator is a cylindrical cavity with an inlet on one side and a conical waste outlet at the bottom. One end of the conical waste outlet is connected to a waste collection tank, and the top of the cyclone separator has an air outlet. The humidification section includes an atomizing humidification pipe, one end of which is connected to the air outlet, and the top end of which is connected to a reuse pipe. This recycling system can reuse previously discarded wool and fine dust, improving raw material utilization and reducing production costs. Cyclone separation effectively removes heavier impurities, ensuring the cleanliness of the reused wool. The humidification section regulates the humidity of the wool, preventing dust or static electricity during reuse and improving the processing stability of subsequent steps.

[0011] Preferably, the first compartment has a separating shaft inside, a feeding shaft below the separating shaft, a feather discharge shaft below the feeding shaft, and a feather discharge outlet below the feather discharge shaft. The second compartment has a second separating shaft at its center inside, with feather discharge outlets below the second separating shaft. The first compartment has multiple equally spaced dispersing shaft assemblies near the top of the first separating shaft, and a down separation baffle is located on one side of each dispersing shaft assembly. This multi-stage separation and feather discharge structure design allows materials to be processed step-by-step in different areas, improving separation accuracy and purity. The dispersing shaft assemblies can break up clumps of material, making them loose for subsequent separation. The down separation baffle effectively blocks down from non-down components, preventing mixing and ensuring product quality. The dual-compartment separating shaft layout enhances the machine's adaptability to processing different materials.

[0012] Preferably, the dispersing shaft assembly includes a longitudinal dispersing shaft with a plurality of stirring rods evenly arranged on it. The stirring rods extend radially along the longitudinal dispersing shaft and are fixed perpendicularly to it. The stirring rods are equidistantly distributed and number 8 to 16. This uniform arrangement of stirring rods applies a balanced shear force to the material, effectively loosening it without damaging the fiber structure. An appropriate number of stirring rods ensures effective dispersing while reducing power consumption and equipment wear, thus extending the service life of the dispersing assembly. Preferably, the cleaning execution component includes a cleaning brush, one end of which is connected to a brush shaft, one end of which is connected to a brush belt, and one end of which is connected to a brush shaft motor. The cleaning brush actively scrapes away accumulated lint and dust from the roller surface, maintaining the roller's permeability and negative pressure adsorption capacity. Automated cleaning reduces manual intervention, avoids production efficiency losses caused by downtime for cleaning, and ensures long-term stable operation of the equipment.

[0013] Preferred: Step 1: Raw material input and initial mixing The raw materials are fed into the processing area of ​​a compartment by the feathering machine through the feather inlet pipe. Inside the compartment, multiple equally spaced dispersing shaft assemblies start working. The longitudinal dispersing shaft drives the evenly distributed stirring rods to rotate, breaking up the lumpy materials and making them loose for subsequent separation. The down separation baffle on one side of the dispersing shaft assembly initially blocks and diverts the down and non-down components during the material flow, preparing for subsequent fine separation. Step Two: Separation of the First and Second Cars The loosened raw material enters the first-stage separation shaft area. Under the action of the separation shaft, the fluff and heavier impurities are further separated. Then, it passes through the first-stage feeding shaft and the first-stage fluff discharge shaft in sequence, and is discharged as finished or semi-finished fluff from the first-stage fluff discharge port. Some of the material that still contains dust and impurities enters the second-stage box located on one side of the bottom of the first-stage box. Under the action of the second-stage separation shaft, it undergoes fine separation and is sent out as purer fluff from the second-stage fluff discharge port, realizing two-stage separation to improve the overall purity. Step 3: Negative pressure roller adsorption and dust collection Inside the two-compartment box, the negative pressure integrated device is activated. The drive roller of the negative pressure roller unit is driven by a roller motor, which drives the roller main shaft to rotate via a roller belt. The flanges at both ends of the drive roller ensure structural stability. The cylindrical cylinder surface is covered with a 12-mesh stainless steel screen to isolate down and prevent down from directly penetrating the roller wall. The grid structure inside the cylindrical cylinder and the negative pressure ports at both ends allow the negative pressure airflow to enter the cylinder evenly, forming a stable negative pressure adsorption zone on the cylinder surface. The residual dust and light impurities in the raw materials are sucked into the exhaust pipe under the action of negative pressure. The bottom of the exhaust pipe is connected to the drive roller, which guides the dust-laden airflow into the main fan. The main fan pressurizes the airflow and sends it into the ash box. The dust settles in the ash box and falls into the ash collection bag through the dust discharge pipe for centralized collection, realizing dust-air separation and closed collection. Step 4: Drum cleaning and waste heat utilization On one side of the negative pressure roller unit, the cleaning execution components operate synchronously. The cleaning brush is driven to rotate by the brush shaft motor through the brush belt, which drives the cleaning brush to gently clean the 12-mesh stainless steel screen on the drive roller inside the two-compartment housing, maintaining the permeability of the roller and the stability of the negative pressure effect. At the same time, the hot air discharged from the main fan enters the finned housing of the waste heat recovery system. This housing consists of an upper air inlet, a middle finned heat exchange module, and a lower air outlet. After heat exchange in the finned heat exchange module, the hot air is sent into the inlet pipe through the lower air outlet to preheat the raw materials that are about to enter the equipment, reducing agglomeration or static electricity caused by low temperature and realizing the reuse of thermal energy. Step 5: Waste lint recycling, humidification, and reuse The waste lint recycling system on one side of the ash collection bag begins operation. Lint-laden exhaust gas enters the cylindrical cavity of the cyclone separator, receiving airflow through the inlet. Under centrifugal force, heavier waste slag settles into the conical waste outlet and enters the waste collection tank, while lighter lint is carried by the airflow from the top outlet into the humidification section. The humidification section's atomizing pipes are equipped with micro-mist nozzles, spraying fine water mist that fully contacts the lint, achieving uniform humidification and preventing dust and static electricity. After humidification, the lint undergoes subsequent processing such as drying to adjust to suitable moisture content and bulkiness before being conveyed into the wool-adding machine for reuse in the production process. This achieves efficient recycling and reuse of waste lint, improving raw material utilization and ensuring stable quality of recycled materials. Step Six: Overall Coordination and Closed-Loop Processing Throughout the entire operation, the first and second compartments work collaboratively, with the dispersing shaft assembly, separating shaft, negative pressure roller unit, dust collection unit, cleaning execution components, waste heat recovery system, and waste lint recycling system operating continuously. The raw materials undergo a complete closed-loop process within the equipment, including continuous input, gradual dispersal, multi-stage separation, efficient dust removal, heat energy reuse, and waste recycling. This ensures the purity of the high-lint raw materials and product quality, while also improving production continuity and energy efficiency, and effectively reducing environmental pollution and raw material waste.

[0014] The advantages of this invention are: The high-fiber two-compartment cleaning machine provided by this invention establishes a collaborative working structure between the first and second compartments, enabling raw materials to undergo multiple separation and cleaning processes in a partitioned environment, significantly improving the efficiency and quality of fiber purification. The equipment employs a drum-type negative pressure integrated device. With the cooperation of the drive drum and dust collection unit, a stable negative pressure zone can be formed during continuous operation, efficiently sucking in and collecting the fiber dust, light impurities, and fine particles entrained in the raw materials, effectively reducing scattering and secondary pollution. The cleaning execution component continuously removes the fiber dust adhering to the surface during drum operation, maintaining the drum's permeability and suction stability, and preventing clogging that leads to performance degradation. The direct connection between the fiber inlet tube and the fiber addition machine ensures continuous and reliable raw material input, reducing manual feeding. The grid-like structure and bidirectional negative pressure ports designed inside the negative pressure drum result in more uniform airflow distribution, improving separation efficiency and reducing residue. The waste heat recovery system uses the hot air discharged from the main fan to preheat the raw materials in the fiber inlet tube, reducing the impact of low temperatures on the raw material's condition and simultaneously reducing energy consumption. The waste down recycling system uses cyclone separation and humidification to return reusable down and dust to the production process, improving raw material utilization and controlling the humidity and cleanliness of recycled materials to prevent dust and static electricity. The separation shaft, feeding shaft, down extraction shaft, and dispersing shaft assemblies inside the first and second compartments gradually disperse, separate, and discharge the material in multiple stages. The uniform stirring action of the dispersing shaft assembly loosens clumps of material without damaging the fibers, while the down separation baffles effectively isolate down from other components, ensuring product purity. The overall structure gives the equipment comprehensive advantages such as high-efficiency separation, continuous cleaning, resource recycling, energy saving, and stable production, making it suitable for the fine processing of high-down-content raw materials.

[0036] In this embodiment, the first compartment 1 is equipped with a separation shaft 5, a feeding shaft 6 is located below the separation shaft, a feather discharge shaft 7 is located below the feeding shaft 6, and a feather discharge outlet 8 is located below the feather discharge shaft 7. The second compartment 11 has a second separation shaft 10 located at its center, and a feather discharge outlet 9 is located below the second separation shaft 10. The first compartment 1 has multiple equally spaced dispersing shaft assemblies 2 near the top of the first separation shaft 5, and a down separation baffle is located on one side of each dispersing shaft assembly 2. This multi-stage separation and feather discharge structure design allows materials to be processed step-by-step in different areas, improving separation accuracy and purity. The dispersing shaft assembly 2 can break up clumps of material, making them loose for subsequent separation. The down separation baffle effectively blocks down and non-down components, preventing mixing and ensuring product quality. The dual-compartment separation shaft layout enhances the machine's adaptability to processing different materials.

[0037] In this embodiment, the dispersing shaft assembly 2 includes a longitudinal dispersing shaft 28, on which a plurality of stirring rods 27 are evenly arranged. The stirring rods 27 extend radially along the longitudinal dispersing shaft 28 and are fixed perpendicularly to it. The stirring rods 27 are evenly distributed and number 8 to 16.

Automated cleaning reduces manual intervention, avoids production efficiency losses due to downtime for cleaning, and ensures long-term stable operation of the equipment.

[0038] In this embodiment: Step 1: Raw material input and initial mixing The raw material is fed into the processing area of ​​the box 1 by the feathering machine 3 through the feather inlet pipe 4. Inside the box 1, multiple equally spaced dispersing shaft assemblies 2 start to work. The longitudinal dispersing shaft 28 drives the evenly distributed stirring rods 27 to rotate, dispersing the lumpy material and making it loose for subsequent separation. The down separation baffle on one side of the dispersing shaft assembly 2 initially blocks and diverts the down and non-down components during the material flow, preparing for subsequent fine separation. Step Two: Separation of the First and Second Cars The loosened raw material enters the first compartment separation shaft 5 area. Under the action of the separation shaft, the fluff and heavier impurities are further separated. Then, it passes through the first compartment feeding shaft 6 and the first compartment fluff discharge shaft 7 in sequence, and is discharged as finished or semi-finished fluff from the first compartment fluff discharge port 8. Some of the material that still contains dust and impurities enters the second compartment 11 located on one side of the bottom of the first compartment 1. Under the action of the second compartment separation shaft 10, it undergoes fine separation and is sent out as purer fluff from the second compartment fluff discharge port 9, realizing two-stage separation to improve the overall purity. Step 3: Negative pressure roller adsorption and dust collection Inside the two-compartment housing 11, the negative pressure integrated device is activated. The drive roller 24 of the negative pressure roller unit is driven by the roller motor 26 and rotates the roller main shaft 32 via the roller belt 25. The flanges at both ends of the drive roller 24 ensure structural stability. The cylindrical cylinder surface is covered with a 12-mesh stainless steel screen 43 to isolate down and prevent down from directly penetrating the roller wall. The grid structure inside the cylindrical cylinder and the negative pressure ports 29 at both ends allow the negative pressure airflow to enter the cylinder evenly, forming a stable negative pressure adsorption zone on the cylinder surface. The residual dust and light impurities in the raw materials are sucked into the exhaust pipe 23 under the action of negative pressure. The bottom of the exhaust pipe 23 is connected to the drive roller 24, which guides the dust-laden airflow into the main fan 19. The main fan 19 pressurizes the airflow and sends it into the ash box 20. The dust settles in the ash box 20 and falls into the ash collection bag 22 through the dust discharge pipe 21 for centralized collection, realizing dust-air separation and closed collection. Step 4: Drum cleaning and waste heat utilization On one side of the negative pressure roller unit, the cleaning execution component 12 operates synchronously. The cleaning brush 16 is driven to rotate by the brush shaft motor 18 through the brush belt 17, which drives the cleaning brush 16 to perform flexible cleaning on the 12-mesh stainless steel screen 43 on the drive roller 24 inside the two-compartment box 11, maintaining the permeability of the roller and the stability of the negative pressure effect. At the same time, the hot air discharged by the main fan 19 enters the finned box 33 of the waste heat recovery system 14. The box consists of an upper air inlet 34, a middle finned heat exchange module 35, and a lower air outlet 36. After the hot air undergoes heat exchange in the finned heat exchange module, it is sent into the inlet tube 4 through the lower air outlet 36 to preheat the raw materials that are about to enter the equipment, reduce agglomeration or static electricity caused by low temperature, and realize the reuse of thermal energy. Step 5: Waste lint recycling, humidification, and reuse The waste wool recycling system 15 on one side of the ash collection bag 22 starts working. The wool-containing waste gas enters the cylindrical cavity of the cyclone separator 40, receives the airflow through the feed inlet 39, and under centrifugal force, the heavier waste slag sinks into the conical waste discharge outlet 41 and enters the waste slag collection tank 42, while the lighter wool material enters the humidification section from the top air outlet with the airflow. The atomizing humidification pipe 38 in the humidification section is equipped with micro-mist nozzles, which spray fine water mist to fully contact the wool material, achieving uniform humidification and avoiding dust and static electricity. After humidification, the wool material undergoes subsequent processing such as drying to adjust to a suitable moisture content and fluffiness, and then is conveyed into the wool-adding machine 3 to be put back into the production process, realizing the efficient recycling and reuse of waste wool, improving the utilization rate of raw materials and ensuring the stable quality of recycled materials. Step Six: Overall Coordination and Closed-Loop Processing Throughout the entire operation, the first and second compartments (11) work together, with the dispersing shaft assembly (2), separation shaft, negative pressure roller unit, dust collection unit, cleaning execution assembly (12), waste heat recovery system (14), and waste lint recycling system (15) operating continuously. The raw materials undergo a complete closed-loop process within the equipment, including continuous input, gradual dispersal, multi-stage separation, efficient dust removal, heat energy reuse, and waste recycling. This ensures the purity of the high-lint raw materials and product quality, improves production continuity and energy efficiency, and effectively reduces environmental pollution and raw material waste.

10. A method for processing down feathers using a high-down two-compartment machine with roller-type negative pressure as described in claim 1, characterized in that: Step 1: Raw material input and initial mixing The raw material is fed into the processing area of ​​the box (1) by the wool addition machine (3) through the wool inlet pipe (4). Inside the box (1), multiple equally spaced dispersing shaft assemblies (2) start to work. The longitudinal dispersing shaft (28) drives the evenly distributed stirring rods (27) to rotate, dispersing the lumpy material and making it loose for subsequent separation. The down separation baffle on one side of the dispersing shaft assembly (2) initially blocks and diverts the down and non-down components during the material flow, preparing for subsequent fine separation. Step Two: Separation of the First and Second Cars After being loosened, the raw material enters the area of ​​the first-stage separation shaft (5). Under the action of the separation shaft, the fluff and heavier impurities are further separated. Then, it passes through the first-stage feeding shaft (6) and the first-stage fluff discharge shaft (7) in sequence, and is discharged as finished or semi-finished fluff from the first-stage fluff discharge port (8). Some of the material that still contains dust and impurities enters the second-stage box (11) located on one side of the bottom of the first-stage box (1). Under the action of the second-stage separation shaft (10), it is finely separated and sent out as purer fluff from the second-stage fluff discharge port (9), thus achieving two-stage separation to improve the overall purity. Step 3: Negative pressure roller adsorption and dust collection Inside the two-compartment box (11), the negative pressure integrated device is activated. The drive roller (24) of the negative pressure roller unit is driven by the roller motor (26) and drives the roller main shaft (32) to rotate through the roller belt (25). The flanges at both ends of the drive roller (24) ensure the structural stability. The cylindrical cylinder surface is covered with a 12-mesh stainless steel screen (43) for isolating down, preventing down from directly penetrating the roller wall. The grid structure inside the cylindrical cylinder and the negative pressure ports (29) at both ends allow the negative pressure airflow to enter the cylinder evenly, forming a stable negative pressure adsorption zone on the cylinder surface. The residual dust and light impurities in the raw materials are sucked into the air duct (23) under negative pressure. The bottom of the air duct (23) is connected to the drive roller (24), which guides the dust-laden airflow into the main fan (19). The main fan (19) pressurizes the airflow and sends it into the ash box (20). The dust settles in the ash box (20) and falls into the ash collection bag (22) through the dust discharge pipe (21) for centralized collection, thereby achieving dust-air separation and closed collection. Step 4: Drum cleaning and waste heat utilization On one side of the negative pressure roller unit, the cleaning execution component (12) operates synchronously. The cleaning brush (16) is driven to rotate by the brush shaft motor (18) through the brush belt (17), which drives the cleaning brush (16) to perform flexible cleaning on the 12-mesh stainless steel screen (43) on the drive roller (24) inside the two-compartment box (11), maintaining the permeability of the roller and the stability of the negative pressure effect. At the same time, the hot air discharged by the main fan (19) enters the finned box (33) of the waste heat recovery system (14). The box consists of an upper air inlet (34), a middle finned heat exchange module (35) and a lower air outlet (36). After the hot air undergoes heat exchange in the finned heat exchange module, it is sent into the inlet tube (4) through the lower air outlet (36) to preheat the raw materials that are about to enter the equipment, reduce the agglomeration or static electricity caused by low temperature, and realize the reuse of thermal energy. Step 5: Waste Wool Recycling and Reuse The waste wool recycling system (15) on one side of the ash collection bag (22) starts working. The wool-containing waste gas enters the cylindrical cavity of the cyclone separator (40) and receives the airflow through the feed port (39). Under centrifugal action, the heavier waste slag sinks into the conical waste discharge port (41) and enters the waste slag collection tank (42). The lighter wool material enters the humidification section from the top air outlet with the airflow. The atomizing humidification pipe (38) of the humidification section enters the airflow from the air outlet and humidifies the wool material through water mist. The humidified wool material is returned to the production process through the recycling pipe (37) to realize the reuse of waste wool, improve the utilization rate of raw materials and control the humidity and cleanliness of recycled materials. Step Six: Overall Coordination and Closed-Loop Processing Throughout the entire process, the first compartment (1) and the second compartment (11) work together, with the dispersing shaft assembly (2), separation shaft, negative pressure roller unit, dust collection unit, cleaning execution assembly (12), waste heat recovery system (14) and waste lint recycling system (15) operating continuously. The raw materials undergo a complete closed-loop process in the equipment, including continuous input, gradual dispersing, multi-stage separation, efficient dust removal, heat energy reuse and waste recycling.
