DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present disclosure will be described based on the drawings. Note that the present disclosure is not limited to the following embodiments, and appropriate design changes can be made within the scope of the configuration of the present disclosure. In addition, in the following description, the same parts or parts having similar functions are commonly used with the same reference numerals in different drawings, and repeated description thereof will be omitted. In addition, each configuration described in the embodiment and the modified example may be appropriately combined or modified. In addition, in order to make the description easier to understand, in the drawings referred to below, the configuration is shown simplified or schematic, and some components are omitted.

[0012] [First embodiment] (Overall structure of the resource circulation system) 1 is a diagram for explaining the overall configuration of a resource circulation system 100. The resource circulation system 100 is a system in which greenhouse gases in at least one of the air or atmosphere exhausted from humans, animals, or equipment and the natural environment are absorbed (removed) by an absorption unit 10 including an absorption member 11, and a product produced by absorbing the greenhouse gases is used to manufacture raw materials for recycled products.

[0013] In the resource circulation system 100, the absorption unit 10 is disposed in equipment. In the equipment, the absorption member absorbs a greenhouse gas (for example, carbon dioxide), and at least a part of the absorption member reacts to become a substance different from that before the reaction.

[0014] The "collector" shown in FIG. 1 is a first user who uses the resource circulation system 100, and is a person who collects the post-reaction absorption unit 10 from the equipment. When collecting the absorption unit 10, the collector places a new pre-reaction absorption unit 10 in the equipment. The collector then hands over the collected absorption unit 10. The collector may be a company that manages the equipment, may be a person that uses or owns the equipment, or may be a public institution such as a local government.

[0015] The "recycler" shown in FIG. 1 is a second user who uses the resource circulation system 100, and is an entity that produces raw materials for recycled products using the absorbing member 11 of the absorption unit 10 after the reaction as a resource. The recycler may be a manufacturer of the raw materials for the recycled products, or a public institution such as a local government. A collector may also serve as a recycler. The raw materials for the recycled products are then utilized in people's lives, and resources are circulated as shown in FIG. 1.

[0016] (Configuration of absorption unit) FIG. 2 is a diagram showing the configuration of the absorption unit 10. In the first embodiment, the absorption unit 10 is disposed in a vending machine 20 (see FIG. 4). The absorption unit 10 is a greenhouse gas absorption filter (carbon dioxide absorption filter). The absorption member 11 contains a hydroxide that absorbs carbon dioxide by chemical reaction. That is, the absorption member 11 is a member that removes carbon dioxide from the air by chemically reacting with carbon dioxide in the air when it comes into contact with the air. The member that absorbs carbon dioxide by chemical reaction contains a calcium-based material. An example of the calcium-based material is calcium hydroxide. In addition to the method using a chemical reaction, there is a method of physically adsorbing carbon dioxide molecules into the pores of the absorption member without causing a chemical reaction. For example, there is a method of adsorbing carbon dioxide molecules into a porous material such as zeolite. In this method of physically adsorbing carbon dioxide molecules into the absorption member, a process of desorbing carbon dioxide from the absorption member and changing the desorbed carbon dioxide into a solid is required, and the number of processes until carbon dioxide is solidified is increased. In contrast, according to the configuration of the first embodiment, by using a member that absorbs carbon dioxide through a chemical reaction, carbon dioxide can be collected in a solid (powder) state in which the carbon dioxide has undergone a chemical change. This makes it easier to reuse carbon dioxide compared to a method in which carbon dioxide molecules are physically adsorbed onto an absorbing member. Note that hydroxides other than calcium hydroxide may be contained in the absorbing member 11. For example, sodium hydroxide, magnesium hydroxide, ammonium hydroxide, or potassium hydroxide may be contained in the absorbing member 11.

[0017] Furthermore, by using calcium hydroxide for the absorbing member 11, calcium carbonate can be produced by absorbing carbon dioxide into the calcium hydroxide. The produced calcium carbonate can be used when producing raw materials for various recycled products. Furthermore, since calcium hydroxide can absorb carbon dioxide in the air simply by being placed in the air, carbon dioxide in the air can be absorbed into the absorbing member simply by placing the absorbing member in a vending machine.

[0018] The absorbing member 11 contains a dye such as methyl violet, and is configured to change color depending on the amount of carbon dioxide absorbed. For example, the absorbing member 11 changes from "white" to "red, purple, or pink" when carbon dioxide is absorbed. The absorbing member 11 may be one that changes from "red or purple" to "white or pink" when carbon dioxide is absorbed, or one that changes to a color other than the above.

[0019] The absorbing member 11 is formed in a granular shape. As shown in Fig. 2, a plurality of the absorbing members 11 are arranged in the case portion 12. By forming the absorbing member 11 from a solid, it is easier to handle than a liquid, and the absorbing member 11 is less likely to adhere to the collector when the collector replaces the absorption unit 10. The case portion 12 has an air hole (not shown) or is formed in a breathable mesh shape. As a result, the case portion 12 allows the absorbing member 11 in the case portion 12 to come into contact with outside air.

[0020] 2, a two-dimensional code 13 is attached to the absorbing unit 10. The two-dimensional code 13 is, for example, a QR code (registered trademark). The absorbing unit 10 may be provided with a one-dimensional code (barcode) instead of the two-dimensional code 13, or may be provided with an electric circuit capable of storing information, such as an IC chip. The two-dimensional code 13 can be used as the "two-dimensional code" described in Japanese Patent No. 7189644, for example.

[0021] (Vending machine configuration) Fig. 3 is a block diagram of the vending machine 20. Fig. 4 is a front view of the vending machine 20. Fig. 5 is a side view of the vending machine 20. Fig. 6 is a view of the vending machine 20 with the front door 31 open.

[0022] As shown in Fig. 4, the absorption unit 10 is disposed in a vending machine 20. The vending machine 20 according to the first embodiment is a carbon dioxide removal device. The absorption unit 10 is disposed, for example, at a position overlapping with the air intake 31a in a front view. The absorption unit 10 is also disposed below the product outlet 31b of the vending machine 20.

[0023] As shown in Figs. 5 and 6, the absorption unit 10 is disposed in an empty space in the housing 30 of the vending machine 20. For example, the absorption unit 10 is disposed inside the front door 31. The absorption unit 10 is disposed below a storage section 33 in the vending machine 20 in which products (e.g., beverage cans) are stored. The housing 30 also has an air passage 34 below the storage section 33, which ventilates the taken-in outside air. The air passage 34 brings the air taken in through the intake port 31a into contact with the compressor 25, and discharges the air from the exhaust port 32a to the outside of the housing 30. The flow speed of the air flowing through the air passage 34 is, for example, 0.1 m / s by the fan 24 described below. 3 / min or more 5m 3 It is set to less than / min.

[0024] The absorption unit 10 is disposed in the ventilation path 34. As shown in Fig. 6, the absorption unit 10 is configured to be detachable from the front door 31 when the front door 31 is open relative to the main body 32 of the housing 30. This allows a collector to easily replace the absorption unit 10 when refilling or replacing products in the storage section 33 in the vending machine 20. The "main body 32" refers to the part of the housing 30 excluding the front door 31.

[0025] 3, the vending machine 20 includes a control unit 21, a carbon dioxide concentration sensor 22, a notification unit 23, a fan 24, a compressor 25, and an operation unit 26. The control unit 21 includes a processor that executes control processes by executing a program. The control unit 21 executes each control process of the vending machine 20.

[0026] The carbon dioxide concentration sensor 22 measures the concentration of carbon dioxide. As shown in FIG. 5, the carbon dioxide concentration sensor 22 is disposed downstream of the absorption unit 10 in the airflow A generated by driving the fan 24. In other words, the carbon dioxide concentration sensor 22 is disposed between the absorption unit 10 and the exhaust port 32a. That is, the carbon dioxide concentration sensor 22 measures the carbon dioxide concentration in the air after carbon dioxide is absorbed by the absorption unit 10. As a result, when the absorption member 11 of the absorption unit 10 is not saturated (for example, the saturation degree is lower than 100%), the carbon dioxide concentration measured by the carbon dioxide concentration sensor 22 becomes lower than the predetermined carbon dioxide concentration. Here, the "predetermined carbon dioxide concentration" is the carbon dioxide concentration outside (environment) of the vending machine 20 that is experimentally measured in advance. Although not shown, a carbon dioxide concentration sensor for measuring the carbon dioxide concentration outside (environment) of the vending machine 20 may be separately provided in the vending machine 20.

[0027] When the absorption unit 10 is in a saturated state (for example, the degree of saturation is nearly 100%), the carbon dioxide concentration measured by the carbon dioxide concentration sensor 22 is equal to or lower than a predetermined carbon dioxide concentration. Since the carbon dioxide concentration sensor 22 is disposed between the absorption unit 10 and the exhaust port 32a, the carbon dioxide in the air that has passed through the absorption unit 10 can be detected by the carbon dioxide concentration sensor 22 before the air that has passed through the absorption unit 10 is mixed with the air outside the housing 30.

[0028] The notification unit 23 is configured as, for example, a display. The notification unit 23 is arranged on the inside of the front door 31, as shown in FIG. 6, for example. When the carbon dioxide concentration measured by the carbon dioxide concentration sensor 22 becomes equal to or lower than a predetermined carbon dioxide concentration, the control unit 21 causes the notification unit 23 to notify the user to replace the absorption unit 10. The notification to prompt the user to replace the absorption unit 10 may be a message display such as "Please replace the absorption unit", a voice output, or a light that turns on. In addition, the control unit 21 cancels (resets) the notification when the collector operates the operation unit 26.

[0029] (Method of manufacturing recycled products according to the first embodiment) The manufacturing method of the recycled product according to the first embodiment will be described with reference to Fig. 7. Fig. 7 is a flow chart showing the manufacturing process of the recycled product according to the first embodiment.

[0030] In step S1, the absorbing member 11 of the absorbing unit 10 arranged in the vending machine 20 is caused to absorb carbon dioxide in the air.

[0031] In step S2, the collector collects the absorption unit 10 placed in the vending machine 20. The absorbing member 11 in the absorption unit 10 may be entirely in a calcium carbonate state, or may be partially in a calcium hydroxide state and partially in a calcium carbonate state. At this time, the collector places a new, unreacted absorption unit 10 in the vending machine 20. The collector replaces the absorption unit 10 when refilling or replacing the products in the vending machine 20. This reduces the workload of the collector when replacing the absorption unit 10.

[0032] In step S3, the collector delivers the collected absorption unit 10 to the recycler. Note that, when the collector, as a recycler, produces raw materials for the following recycled products, step S3 is omitted.

[0033] In step S4, if the absorbent material 11 in a saturated state is calcium carbonate, the reuser uses the absorbent material 11 to manufacture raw materials for recycled products (glass materials, cement (concrete, or mortar)).

[0034] In step S5, a recycled product is manufactured from the raw material of the recycled product. If the raw material of the recycled product is a glass material, a glass bottle is manufactured and a beverage is filled in the glass bottle.

[0035] In step S6, the recycled products are stored in the storage section 33 of the vending machine 20.

[0036] According to the above configuration, it is possible to provide a resource circulation system 100 that reduces greenhouse gases (carbon dioxide) in the atmosphere and circulates resources.

[0037] [Second embodiment] Next, the configuration of a resource circulation system 300 according to a second embodiment will be described with reference to Fig. 8 to Fig. 15. In the second embodiment, an absorption unit 310 is stored together with a product M in a storage section 333 in a vending machine 320. Note that the same components as those in the first or second embodiment are denoted by the same reference numerals as those in the first or second embodiment, and description thereof will be omitted.

[0038] Fig. 8 is a diagram showing the configuration of a resource circulation system 300 according to the second embodiment. Fig. 9 is a diagram showing the configurations of an absorption unit 310 and a case 313 according to the second embodiment. As shown in Fig. 8, the resource circulation system 300 includes an absorption unit 310 and a vending machine 320. In the second embodiment, the absorption unit 310 is disposed in a storage section 333. For example, the absorption unit 310 is inserted into the storage section 333 through a product insertion port 333a of the storage section 333 with the case 313 attached.

[0039] 9, the absorption unit 310 is disposed in a case 313. The absorption unit 310 is configured to be disposed in the case 313 by being inserted through an opening 313a of the case 313, and to be removed by being pulled out through the opening 313a. When collecting the absorption unit 310, a collector removes the absorption unit 310 from the case 313 and replaces only the absorption unit 310.

[0040] As shown in FIG. 9, the case 313 and the absorption unit 310 have a shape that allows them to be accommodated in the accommodation section 333 together with the product M. If the product M is a can containing a beverage or food, for example, the case 313 and the absorption unit 310 have the dimensions of a can stipulated in the JIS Z1571 standard. For example, the absorption unit 310 has a cylindrical shape. If the product M is contained in a plastic bottle or other container, the case 313 and the absorption unit 310 have the same dimensions as the plastic bottle or other container. The case 313 is provided with a plurality of ventilation holes 313b. The absorbing member 11 of the absorption unit 310 absorbs carbon dioxide in the air that has entered through the ventilation holes 313b. A two-dimensional code 13 is arranged on the surface of the absorption unit 310.

[0041] As shown in FIG. 10, the absorption unit 310 includes a case section 312 that houses a plurality of absorption members 11. A space 312a is provided in the case section 312. By providing the space 312a in the case section 312, when the case section 312 rotates, the plurality of absorption members 11 are agitated. For example, as shown in FIG. 11, FIG. 12, and FIG. 13, when a part of the plurality of products M is carried out from the product take-out port 31b (when one product M is sold), the absorption unit 310 moves while rotating in the storage section 333. This agitates the plurality of absorption members 11 in the absorption unit 310. As a result, the absorption members 11 that are easily exposed to air and the absorption members 11 that are not easily exposed to air are replaced in the absorption unit 310 among the plurality of absorption members 11, so that the plurality of absorption members 11 can be uniformly exposed to air. As a result, it is possible to prevent only a part of the absorption members 11 from being saturated and the rest from being in an unreacted state.

[0042] FIG. 14 is a block diagram of a vending machine 320 according to the second embodiment. As shown in FIG. 14, the vending machine 320 includes a control unit 321, a sold-out sensor 322, and an operation unit 326. The sold-out sensor 322 includes, for example, a switch that detects the presence or absence of a biasing force against the product M or the absorption unit 310 (case 313). When a biasing force is present, the sold-out sensor 322 determines that the product M or the absorption unit 310 (case 313) is present. Here, in the second embodiment, as shown in FIG. 13, the sold-out sensor 322 detects that the product M is sold out when only the absorption unit 310 is placed in the storage section 333. The control unit 321 stops the sale of the product M that is detected as sold out by the sold-out sensor 322. This makes it possible to prevent the absorption unit 310 from being mistakenly provided to a user who is trying to purchase the product M.

[0043] When an input operation is performed by the collector, the operation unit 326 lowers the lever 333b and carries the absorbing unit 310 (case 313) out of the product removal opening 31b, as shown in Fig. 15. The operation unit 326 is operated when the collector collects the absorbing unit 310. The operation unit 326 is, for example, a physical button. Note that the operation unit 326 is not limited to a physical button and may be a touch panel.

[0044] According to the above configuration, the storage section 333 can be used as a space for arranging the absorption unit 310. Then, by simply putting the absorption unit 310 together with the product M into the storage section 333, the absorption unit 310 can start absorbing carbon dioxide while replenishing the product M.

[0045] (Method for producing raw materials for recycled products according to the second embodiment) A method for producing raw materials for recycled products according to the second embodiment will be described with reference to Figures 8, 9, 11 to 13, 15 and 16. Figure 16 is a flow diagram showing a manufacturing process of raw materials for recycled products according to the second embodiment.

[0046] In step S21, the absorption unit 310 is stored together with the product M in the storage section 333 of the vending machine 320, as shown in FIGS.

[0047] In step S22, the absorption unit 310 in the storage section 333 absorbs carbon dioxide in the air.

[0048] In step S23, as shown in FIG. 12, the absorbing unit 310 moves as a result of the product M being sold (carried out), and the absorbing member 11 is agitated within the absorbing unit 310.

[0049] In step S24, when only the absorption unit 310 is contained in the container 333, the sold-out sensor 322 detects that the unit is sold out.

[0050] In step S25, the collector replaces the absorption unit 310. In detail, the collector operates the operation unit 326, and the absorption unit 310 is carried out from the vending machine 320. The collector removes the absorption unit 310 from the case 313, and places a new absorption unit 310 in the case 313. As shown in FIG. 11 , the collector refills the storage section 333 with the product M, and then finally puts the absorption unit 310 that was placed in the case 313 into the storage section 333.

[0051] In step S26, the collector delivers the collected absorption unit 310 to the reuser.

[0052] In step S27, a raw material for a recycled product is produced by a reuser using the absorbing member 11 of the absorbing unit 310. In step S28, the raw material for a recycled product is utilized.

[0053] According to the above method, simply by putting the absorbing unit 310 into the storage section 333 together with the product M, the absorbing unit 310 can start absorbing carbon dioxide while replenishing the product M.

[0054] [Variations] As described above, the above-described embodiments are merely examples for implementing the present disclosure. Therefore, the present disclosure is not limited to the above-described embodiments, and can be implemented by appropriately modifying the above-described embodiments without departing from the spirit of the present disclosure.

[0055] (1) In the above first and second embodiments, an example in which the absorption unit is disposed in a vending machine or an anesthesia circulation system has been described, but the present disclosure is not limited thereto. For example, the absorption unit may be disposed in a device according to the modified example shown in Figs. 17 to 21. As shown in Fig. 17, a vacuum cleaner 420 according to the first modified example includes a paper pack 421, a fan 422, and a motor 423. The absorption unit 410 is disposed between the paper pack 421 and the fan 422. The absorption unit 410 is also disposed between the motor 423 and an exhaust port 424 of the vacuum cleaner 420. As a result, when the fan 422 is driven by the motor 423, air passes through the absorption unit 410, and carbon dioxide in the air is absorbed by the absorption unit 410.

[0056] 18, the vacuum cleaner 420a according to the second modification includes a cyclone chamber 421a, a dust collection chamber 422a, a motor 423a, and a mesh filter 424a. The absorption unit 410a is disposed between the dust collection chamber 422a and the motor 423a. As a result, when the motor 423a is driven, the airflow generated in the cyclone chamber 421a causes air to pass through the absorption unit 410a, and carbon dioxide in the air is absorbed by the absorption unit 410a.

[0057] 19, air conditioner 520 according to the third modification includes filter 521, heat exchanger 522, and fan 523. Air conditioner 520 according to the third modification is disposed on a wall. Absorption unit 510 is disposed between filter 521 and heat exchanger 522. Absorption unit 510 is disposed downstream of heat exchanger 522. Thus, air passes through absorption unit 510 by an airflow generated by fan 523, and carbon dioxide in the air is absorbed by absorption unit 510.

[0058] As shown in Fig. 20, the air conditioner 520a according to the fourth modification includes a filter 521a, a heat exchanger 522a, and a fan 523a. The air conditioner 520a according to the fourth modification is disposed on the ceiling. The absorption unit 510a is disposed between the filter 521a and the fan 523a. As a result, air passes through the absorption unit 510 by the airflow generated by the fan 523a, and carbon dioxide in the air is absorbed by the absorption unit 510a.

[0059] 21 , the ventilation fan 620 according to the fifth modified example includes a filter 621 and a fan 623. The absorption unit 610 is disposed between the filter 621 and the fan 623. As a result, air passes through the absorption unit 610 by an airflow generated by the fan 623, and carbon dioxide in the air is absorbed by the absorption unit 610.

[0060] Regardless of the first to fourth modifications, the absorption unit may be disposed in any of an air purifier, an electric fan, a dehumidifier, a humidifier, a cooking appliance such as a gas range, a car, a train, a bus, and a taxi, or the absorption unit may be disposed without being disposed in the appliance and the greenhouse gas may be absorbed by the absorption unit. In addition, the absorption unit may be disposed not only in the above appliances but also in a boiler, an incinerator, a thermal power generator, a wind power generator, a geothermal power generator, a solar power generator, other machinery, a utility pole, a mailbox, a gas meter, a water meter, furniture, a clock, a light, a wall, a ceiling, a floor, and the like. When the absorption unit is provided in a car, the absorption unit may be replaced at a gas station or the like.

[0061] (2) In the first and second embodiments, the absorption unit absorbs carbon dioxide as a greenhouse gas, but the present disclosure is not limited to this. That is, the absorption unit may absorb greenhouse gases other than carbon dioxide (e.g., methane, fluorocarbons, etc.).

[0062] (3) In the above first embodiment, glass products and cement (concrete or mortar) are given as examples of raw materials for recycled products produced using calcium carbonate, but the present disclosure is not limited thereto. For example, calcium carbonate may be used to produce fertilizer.

[0063] (4) In the above first and second embodiments, calcium hydroxide is used as the absorbing member, but the present disclosure is not limited to this. For example, the absorbing member may be a porous material such as a mineral such as zeolite, a hollow fiber membrane, or any other material capable of absorbing and adsorbing carbon dioxide.

[0064] (5) In the first and second embodiments, the granular absorbent member is used, but the present disclosure is not limited to this. For example, the absorbent member may be formed into a powder.

[0065] (6) In the first embodiment, the absorption unit is disposed on the front door, but the present disclosure is not limited to this. For example, the absorption unit may be disposed in an air passage in the vending machine other than the front door. For example, if the vending machine is provided with a duct that constitutes the air passage, the absorption unit may be disposed in the duct.

[0066] (7) In the above first embodiment, the absorption unit is disposed inside the vending machine, but the present disclosure is not limited to this. The absorption unit may be attached to the outside of the vending machine.

[0067] (8) In the first embodiment, a fan is provided in the ventilation path of the vending machine, but the present disclosure is not limited to this. That is, a fan does not have to be provided in the ventilation path.

[0068] (9) In the first and second embodiments, the absorption unit may further be provided with a fan for blowing air to the absorbing member.

[0069] (10) In the second embodiment, as shown in FIG. 11, an example in which one absorption unit is arranged in the storage section is shown, but the present disclosure is not limited to this. A plurality of absorption units may be arranged in the storage section. For example, a plurality of absorption units may be arranged so as to fill one row of shelves in the storage section. In this case, the absorption units can be prevented from being carried out by stopping the sale of this row of products.

[0070] (11) In the above second embodiment, an example in which the absorption unit is replaced among the case and the absorption unit has been described, but the present disclosure is not limited to this. For example, both the case and the absorption unit may be replaced, or the case may not be provided.

[0071] (12) In the above first and second embodiments, the absorption member that absorbed the greenhouse gas is reused (recycled), but the present disclosure is not limited to this. For example, the absorption member that absorbed the greenhouse gas may be stored underground or in the sea.

[0072] The above-mentioned configuration can be explained as follows.

[0073] The device according to the first configuration includes an absorption unit including an absorption member that absorbs greenhouse gases in a gas (first configuration).

[0074] According to the first configuration, it is possible to reduce greenhouse gases.

[0075] A vending machine according to a second configuration includes a storage section that stores products, and an absorption unit that includes an absorption member that absorbs greenhouse gases in the gas (second configuration).

[0076] According to the second configuration, a vending machine capable of reducing greenhouse gas emissions can be provided.

[0077] In the second configuration, the greenhouse gas may include carbon dioxide. The absorbing member may include a member that absorbs carbon dioxide through a chemical reaction (third configuration).

[0078] Here, the method of physically adsorbing carbon dioxide molecules to the absorbing member requires a process of desorbing carbon dioxide from the absorbing member and changing the desorbed carbon dioxide into a solid. This increases the number of processes required to turn carbon dioxide into a solid. In contrast, if a member that absorbs carbon dioxide through a chemical reaction is used as in the third configuration, carbon dioxide can be collected in a solid (powder) state where the carbon dioxide has been chemically changed. This makes it easier to reuse the absorbing member by using solid carbon dioxide, compared to the method of physically adsorbing carbon dioxide molecules into the absorbing member.

[0079] In the third configuration, the member that absorbs carbon dioxide through a chemical reaction may contain calcium hydroxide (fourth configuration).

[0080] According to the fourth aspect, calcium carbonate can be produced by absorbing carbon dioxide into calcium hydroxide. The produced calcium carbonate can be used to produce raw materials for various recycled products. In addition, calcium hydroxide can absorb carbon dioxide in the air simply by being placed in the air, so that carbon dioxide in the air can be absorbed by the absorbing member simply by placing the absorbing member in the vending machine.

[0081] In any one of the second to fourth configurations, the vending machine may further include a housing including an intake port and an exhaust port. The absorbing member may be disposed on an air passage between the intake port and the exhaust port (fifth configuration).

[0082] According to the fifth configuration, the absorbing member can be brought into contact with the air passing through the housing of the vending machine, which eliminates the need to provide a dedicated duct or the like for guiding air to the absorbing member.

[0083] In the fifth configuration, the absorption unit may be disposed below the storage section within the housing (sixth configuration).

[0084] According to the sixth configuration, the absorption unit can be placed in an empty space inside the vending machine.

[0085] In any one of the second to fourth configurations, the absorption unit may be disposed inside the storage section (seventh configuration).

[0086] According to the seventh configuration, the storage section can be used as a space for arranging the absorption unit.

[0087] In the seventh configuration, the absorption unit may be configured to have a shape that allows it to be contained in the container together with the product (eighth configuration).

[0088] According to the eighth configuration, when replacing or replenishing the product, the absorption unit can be disposed or replaced together with the product.

[0089] In a first configuration, the device has an air passage in which the absorption unit is disposed, and the flow rate of air flowing through the air passage is 0.1 m 3 / min or more 5m 3 / min (ninth configuration).

[0090] According to the ninth configuration, the absorption unit can efficiently absorb greenhouse gases.

[0091] The greenhouse gas absorption unit according to the tenth configuration comprises an absorption member that absorbs greenhouse gases in a gas, and a case portion that houses the absorption member therein, the case portion having a shape that allows it to be stored together with products in a storage portion of a vending machine (tenth configuration).

[0092] According to the tenth configuration, when the product is replaced or replenished, the greenhouse gas absorption unit can be disposed or replaced together with the product. [Explanation of symbols]
