Description

  The present invention relates to a garbage disposal method.

  Generally, garbage is collected from each household and incinerated in a garbage incinerator at a municipal waste disposal plant. Garbage incinerators treat garbage by putting it into the combustion chamber. However, because garbage contains a lot of water, it has been proposed to remove moisture from the garbage and then throw it into the combustion chamber. . However, raw garbage is collected from each household while containing moisture and transported to the waste treatment plant, so it is bulky and heavy, and transporting it to a distant landfill will reduce the transportation cost. An increase is incurred.

  Incineration of a large amount of garbage not only generates toxic gases such as dioxins but also releases a large amount of greenhouse gases such as carbon dioxide (CO2) into the atmosphere. Therefore, it is desirable to reduce the amount of garbage to be incinerated in order to suppress global warming. In addition, when a large amount of garbage is collected beyond the processing capacity of the garbage treatment plant, the garbage is left unattended, which causes problems such as generation of malodors and pests (such as worms). In addition, incineration of food waste requires high fuel costs, increasing the burden on local governments and households.

  By the way, raw garbage is about 20% to 30% of vegetable waste including about 70% to 80% of the whole water, such as vegetable scraps and fruit peels, and food residue, meat, and fish. It is roughly divided into two types: meat-based garbage containing the moisture. Of these, vegetable-based garbage can be considerably reduced in bulk and weight by drying with sun-dried for about a week, etc. For example, garbage can be collected by drying the garbage in each home, etc. It is possible to reduce transportation costs to the treatment plant. On the other hand, meat-based garbage does not reduce its bulk and weight so much even when dried, so the problem of transportation cost still remains.

  In addition, it is often proposed to compost fermented garbage from a composting plant without incinerating the garbage. However, in order to ferment the garbage, it is necessary to remove moisture from the garbage. For this reason, a large scale dehydration facility and a vast sun-drying space are required, which is difficult to achieve in urban areas and must be carried out in areas far from the urban areas. As a result, there is a cost for transporting garbage to areas far from the metropolitan area, and the problem of transport cost has not been solved.

  In addition, attempts have been made to ferment raw garbage for composting, but it is difficult to continuously achieve optimum fermentation conditions over a long period of time. In patent document 1, the proposal of collect | recovering raw garbage easily without putting so much burden on each household is made | formed. In Patent Document 1, raw garbage is introduced into a storage container together with compost and fermented, and then accumulated in a composting space to further ferment the fermented material and compost. Subsequently, it is disclosed that the compost is divided into small portions, distributed, placed in a storage container together with food waste, and fermented sequentially. In this patent document 1, since the garbage is reduced in volume and reduced in weight and can be collected in a state where there is not so much offensive odor, composting of the collected garbage is compared with the case where the garbage is treated as it is. It can be done in a short period of time with small equipment.

  In addition, when raw garbage is fermented and composted, pests such as worms are often generated during the fermentation process of the raw garbage, which is an environmental health problem. When composting garbage, it is considered to seal the container so that insects do not enter, but the current situation is that it has not been able to effectively prevent the generation of pests. In addition, the use of chemical substances (insecticides) to control pests can be considered, but there are many cases where the insecticidal effects of chemicals are diminished due to the resistance to adults and the like, and there is also concern about the harmful effects of insecticides on human bodies. The

Japanese Patent Laid-Open No. 2003-081685

  In Patent Document 1, a plurality of complicated processes must be performed although the equipment cost and the like can be suppressed. Therefore, while not burdening each household so much, the process is complicated and it is difficult to think that the burden is reduced as a result. In particular, since a complicated process is performed in producing seed compost used when fermenting raw garbage and composting, it is difficult to easily perform such a series of processes. Moreover, in patent document 1, it cannot be said that it is enough about generation | occurrence | production prevention of pests which generate | occur | produce garbage, and suppression of a bad smell.

  In view of the circumstances as described above, in the present invention, a garbage disposal method capable of easily and reliably composting at least meat-based garbage among garbage in a simple manner while suppressing generation of malodor and pests. The purpose is to provide.

  The present invention is a method for treating raw garbage, separating meat-based garbage and vegetable-based garbage from raw garbage, storing the meat-based garbage in a container with a lid, rice bran, lactic acid bacteria and yeast It is characterized by composting meat-based food waste by putting a fermenting agent mixed with the above-mentioned complex and indigenous bacteria into a container, mixing it with meat-based food waste to form a mixture, and aging the mixture And

  Moreover, you may use what mixed the fermenting agent with the ratio of the composite 0.2-0.6 and indigenous bacteria 3.0-4.0 with respect to the rice bran 100. FIG. Further, a paper bag or a net bag containing at least one of wood chips, sawdust, and wood pieces may be disposed in the container. Further, during or after the aging of the mixture, the mixture may be transferred from the container to a large container having a larger capacity than the container for aging. Moreover, you may process using an earthworm during the aging of a mixture or after aging. The vegetable-based garbage may be stored in an air-permeable container and dried in the sun, or put in a dryer and dried to reduce the volume.

  According to the present invention, among raw garbage, meat-based garbage is stored in a container with a lid, and a fermenting agent mixed with rice bran, a complex of lactic acid bacteria and yeast, and an indigenous fungus is put into the container. Since a mixture is formed and this is aged and composted, it is possible to easily and reliably compost meat-based garbage that causes malodors and pests, among other garbage. At that time, the generation of bad odors and pests is suppressed, so that the influence on the environment can be reduced. Moreover, since it can implement | achieve by a simple method, the processing cost of garbage can be reduced.

  Moreover, the fermenting agent can efficiently compost meat-based food waste by using a mixture of rice bran 100 at a ratio of composite 0.2 to 0.6 and indigenous bacteria 3.0 to 4.0. Can be In addition, by placing a paper bag or net bag containing at least one of wood chips, sawdust, and wood pieces in the container, it can be properly deodorized and used when meat-based garbage is aged. Scrap wood etc. can be easily removed from meat-based garbage. Moreover, composting of meat-based garbage can be performed collectively by transferring the mixture from a container to a large container and aging during or after aging the mixture. Moreover, organic matter can be efficiently decomposed into a form that can be easily used by plants and microorganisms by treating with earthworms during or after aging the mixture. Moreover, vegetable-type garbage can be processed efficiently by storing vegetable-type garbage in the container which has air permeability, drying in the sun, or putting it into a dryer and drying and reducing the volume.

It is a figure which shows an example of the garbage processing method which concerns on embodiment. It is a flowchart which shows the procedure of the garbage processing method. It is a figure which shows another example of the garbage processing method. It is a flowchart which shows the procedure of the garbage processing method shown in FIG. (A) is a figure which shows an example of the container which accommodates vegetable-type garbage, (B) is a figure which shows an example of the dryer which dries vegetable-type garbage.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to the embodiments described below. Further, in the drawings, in order to describe the embodiment, a part or the whole is schematically described, and a part expressed by changing the scale as appropriate, such as a part being enlarged or emphasized, is included. The garbage processing method of this embodiment separates the meat-based garbage MG and the vegetable-based garbage BG from the garbage G, and performs a predetermined process on each. In the present specification, the meat-based garbage MG means animal-based garbage such as meat, fish and shellfish. The vegetable-based garbage BG means plant-based garbage such as vegetables and fruits.

  FIG. 1 is a diagram illustrating an example of a garbage disposal method according to the embodiment. FIG. 2 is a flowchart showing an example of a garbage disposal method. As shown in FIGS. 1 and 2, first, the meat-based food waste MG and the vegetable-based food waste MG are separated from the food waste G (step S1 in FIG. 2). The separation of the garbage G is performed, for example, by an operator's manual work. However, any apparatus that can separate the meat-based garbage MG and the vegetable-based garbage MG may be used. The meat-based garbage MG sorted in step S1 may include a little vegetable-based garbage BG. Note that the meat-based garbage MG does not contain vegetable-based garbage BG containing about 70% to 80% of the total moisture, so that the amount of moisture is small, and the amount of moisture is suitable for the subsequent fermentation (decomposition) treatment. ing.

  Next, the sorted meat-based garbage MG is accommodated in the container 10 (step S2 in FIG. 2). When the meat-based garbage MG is accommodated in the container 10, the meat-based garbage MG may be accommodated in the container 10 after removing a part of the moisture in the meat-based garbage MG. Thereby, the amount of water to be charged in the container 10 can be reduced. The removal of moisture from the meat-based garbage MG is performed by, for example, squeezing the meat-based garbage MG by hand or sandwiching it with a plate material. Further, the meat-based garbage MG may be finely cut when being accommodated in the container 10. Thereby, the time required for fermentation (decomposition) and composting of the meat-based garbage MG can be shortened.

  As shown in FIG. 1, a container with a lid 11 having an opening 10 a on the upper side and a bottom plate 10 b on the lower side is used as the container 10. The container 10 is, for example, a plastic poly bucket having a circular horizontal cross section. The capacity of the container 10 can be, for example, 5 to 20 liters, several tens of liters, or about 100 liters depending on the purpose and purpose. A container 10 having a capacity of 5 to 20 liters can be easily installed in a kitchen, a kitchen, etc., a container 10 having a capacity of several tens of liters can be installed on a veranda or eaves, etc. Can be installed outdoors. A plurality of containers 10 may be used, a plurality of containers having the same capacity may be used, or a plurality of containers having different capacities may be used.

  The shape and material of the container 10 are arbitrary. For example, the container 10 may have a rectangular horizontal cross section, or may be made of a metal such as stainless steel. Moreover, what put the plastic bag etc. in the cardboard box as the container 10 may be used.

  The lid 11 prevents insects, rainwater, and the like from entering the container 10 and suppresses the odor in the container 10 from leaking to the outside. Thereby, the processing of meat-based garbage MG can be performed in a state in which the generation of malodor and pests is suppressed. For example, the lid 11 is placed so as to cover the upper end of the container 10. The lid 11 does not need to seal the inside of the container 10 and may be any one that can suppress at least the entry of insects, rainwater, and the like. The lid 11 may be made of the same material as that of the container 10 or may be made of a different material. Further, the lid 11 may be connected to the upper end of the container 10 by a hinge or the like so that the opening 10a of the container 10 can be opened and closed.

  Next, the fermenting agent 12 which mixed the rice bran, the composite of lactic acid bacteria and yeast, and the indigenous bacteria is put into the container 10 and mixed with the meat-based garbage MG to form a mixture 13 (see FIG. 2 step S3). The fermenting agent 12 is used to ferment the meat-based garbage MG appropriately while suppressing the generation of malodors and pests, and is a mixture of rice bran, a complex of lactic acid bacteria and yeast, and an indigenous fungus. is there. Rice bran includes pericarp, seed coat and germ that are produced when rice is polished. Since rice bran contains abundant nitrogen and minerals necessary for the growth of microorganisms, lactic acid bacteria, yeast and indigenous bacteria described later can be effectively grown in rice bran. In addition, the kind of rice bran is not limited, Arbitrary rice bran can be used.

  The above-mentioned composite contains lactic acid bacteria and yeast and contributes to appropriate fermentation (decomposition) of meat-based garbage MG. Lactic acid bacteria produce lactic acid by lactic acid fermentation, and this lactic acid makes the surrounding pH weakly acidic. Thereby, meat system garbage MG can be processed in a weakly acidic environment. When the environment is weakly acidic, the growth of spoilage bacteria is suppressed, so that spoilage is suppressed and the generation of malodor is suppressed. Moreover, in a weakly acidic environment, the occurrence of pests such as worms and the generation of pathogenic bacteria are also suppressed. Moreover, since lactic acid produced by lactic acid bacteria neutralizes ammonia that causes bad odor, generation of ammonia odor can be suppressed. In the present specification, “lactic acid bacterium” means a bacterium that produces lactic acid by metabolism.

  Any lactic acid bacterium can be used as long as it produces lactic acid by metabolism. For example, facultative anaerobic (conditional anaerobic) lactic acid bacteria can be used as the lactic acid bacteria. When facultative anaerobic lactic acid bacteria are used, meat-based garbage MG can be fermented (decomposed) even when the mixture 13 in the container 10 is not stirred and oxygen is not supplied, so that the meat-based garbage MG is easily treated. be able to. As such lactic acid bacteria, for example, lactic acid bacteria such as Lactobacillus can be used. Lactobacillus is a Gram-positive rod. The lactic acid bacteria may be lactic acid bacteria other than Lactobacillus. Moreover, you may use lactic acid bacteria in mixture of multiple types. As such lactic acid bacteria, for example, various commercial products, those obtained from yogurt, rice soup, etc. can be used.

  Yeast contributes to fermentation (decomposition) of meat-based garbage MG together with lactic acid bacteria. In the present specification, “yeast” refers to a fungus in which a nutrient body is unicellular for a certain period of the life cycle. Any yeast can be used as long as it survives with lactic acid bacteria. Moreover, you may use yeast, mixing multiple types. As such yeast, for example, various commercially available products, those obtained from fruits, plants and the like can be used.

  In addition, as long as the above-mentioned composite contains lactic acid bacteria and yeast, it may contain other bacteria (microorganisms), other components, other materials, and the like. The composite may include, for example, a material for engrafting microorganisms such as filamentous fungi and actinomycetes and microorganisms contained in the fermenting agent. Moreover, as the above-described composite, a commercially available product may be used. As a commercially available composite, a brand name "Lactobacillus" (made by Daishin Co., Ltd.) etc. can be used, for example.

  Indigenous bacteria contribute to the fermentation (decomposition) of meat-based garbage MG together with the composite. Moreover, indigenous bacteria suppress the odor generated at the time of fermentation (decomposition) of meat-based garbage MG. In the present specification, “indigenous bacteria” means a group of microorganisms that inhabit soil, and include, for example, bacteria, actinomycetes, filamentous fungi, algae, and the like. Since most of the indigenous bacteria decompose organic substances and convert them into inorganic substances, the meat-based garbage MG can be effectively fermented (decomposed) by using the indigenous bacteria. Any indigenous bacteria can be used. Indigenous bacteria can be easily obtained from soil such as mulch. Indigenous bacteria may be commercially available. As commercially available indigenous bacteria, for example, the trade name “Morinohana” (manufactured by Suo City) and the like can be used.

  As the ratio of the rice bran, the composite and the indigenous bacteria, the fermenting agent 12 is, for example, a composite 0.2 to 0.6 (part by weight) and an indigenous bacteria 3.0 to 4 with respect to 100 (parts by weight) of rice bran 0.0 (parts by weight) is used. By setting it as this ratio, since lactic acid bacteria, yeast, and an indigenous microbe can be propagated appropriately in rice bran, fermentation (decomposition) of meat system garbage MG can be performed effectively. In addition, the ratio of the rice bran, the composite, and the indigenous bacteria in the fermenting agent 12 may be other than the above.

  Further, the fermenting agent 12 may be used after mixing the rice bran with the composite and the indigenous bacteria and then leaving it for a predetermined period. In this case, microorganisms such as lactic acid bacteria, yeast, and indigenous bacteria are grown in the rice bran, so that the fermentation (decomposition) of the meat-based garbage MG can be performed effectively. The predetermined period is appropriately set depending on the type and use of microorganisms in lactic acid bacteria, yeast, indigenous bacteria, and the like, but is usually about 10 days to several months. In addition, the fermenting agent 12 may contain other fungi (microorganisms), other components, other materials, and the like. The composite may include, for example, a material for engrafting microorganisms such as filamentous fungi and actinomycetes and microorganisms contained in the fermenting agent.

  The fermenting agent 12 is sprayed on the meat-based garbage MG accommodated in the container 10 and mixed by a manual operation or a stirring device to become a mixture 13. Further, as shown in FIG. 1, the meat-based garbage MG is put on the mixture 13 previously stored in the container 10, and the operation of spraying the fermenting agent 12 on the meat-based garbage MG is repeated. It is. The meat-based garbage MG and the fermenting agent 12 may be mixed and then stored in the container 10. The input amount of the fermenting agent to the meat-based garbage MG is appropriately set according to the type of the fermenting agent 12 and the like. For example, the fermenting agent 12 is 5 to 10 parts by weight with respect to 100 parts by weight of the meat-based garbage MG. Degree. In addition, rice bran, a composite, and an indigenous microbe may be thrown into the container 10 separately. In addition, one or two of rice bran, a composite, and an indigenous bacterium may be additionally added to the container 10.

  Next, the paper bag 15 containing the wood chips 14 is placed in the container 10 (step S4 in FIG. 2). Odor in the container 10 can be deodorized by the wood waste 14 in the paper bag 15, and bad odor can be suppressed. The arrangement location of the paper bag 15 is not limited, and can be arranged at any location in the container 10. For example, as shown in FIG. 1, a paper bag 15 may be disposed on the mixture 13. Further, in addition to the wood waste 14, sawdust, wood pieces, or a mixture thereof may be accommodated in the paper bag 15. A net bag may be used instead of the paper bag 15. Whether or not such a paper bag 15 is arranged in the container 10 is arbitrary.

  Moreover, since the wood waste 14 etc. are accommodated in the paper bag 15 grade | etc., It can collect | recover from the container 10 easily. In addition, the kind of wood chips 14 etc. is not specifically limited, Arbitrary things can be used. Further, the wood waste 14 etc. accommodated in the paper bag 15 etc. can be used in any amount.

  Next, the mixture 13 accommodated in the container 10 is aged (step S5 in FIG. 2). Ripening is a so-called primary fermentation stage in which low-molecular organic substances (saccharides and amino acids) are decomposed. The mixture 13 is appropriately fermented (decomposed) and composted while the generation of malodors and pests is suppressed by the lactic acid bacteria of the fermenting agent 12 and the like. Aging of the mixture 13 is performed in the container 10 for a predetermined period. This predetermined period varies depending on the amount and type of meat-based garbage MG, temperature and humidity. Further, the container 10 (mixture 13) may be heated at the time of aging.

  Next, the mixture 13 is composted (step S6 in FIG. 2). Composting of the mixture 13 may be performed in the container 10, or may be performed by mixing the mixture 13 and soil, for example. By mixing with soil, fermentation (decomposition) of the mixture 13 further proceeds by soil organisms and indigenous bacteria that inhabit the soil, and composting of the mixture 13 is promoted. For example, the aged mixture 13 may be carried to a garden or the like and mixed with a predetermined amount of soil, or the mixture 13 and soil may be mixed in the container 10. Alternatively, the mixture 13 may be filled in a hole dug in the soil. Moreover, you may perform the process which uses the earthworm mentioned later with respect to the mixture 13 during composting or after composting.

  As described above, according to steps S1 to S6 described above, the meat-based garbage MG can be easily composted while suppressing the generation of malodor and pests. In addition, the process of vegetable type garbage BG shown in FIG.1 and FIG.2 is mentioned later.

  FIG. 3 is a diagram illustrating another example of the garbage disposal method. FIG. 4 is a flowchart showing a procedure of the garbage disposal method shown in FIG. As shown in FIGS. 3 and 4, after the mixture 13 is aged (composted) in the container 10, the mixture 13 in the container 10 is transferred to the large container 20 having a larger capacity than the container 10 and aged. (Step S10 in FIG. 4). The aging and composting of the mixture 13 in the container 10 is the same as the method shown in steps S1 to S6 shown in FIGS.

  FIG. 3 shows an example in which the mixture 13 is transferred from at least one container 10 to the large container 20. The mixture 13 may be transferred from the plurality of containers 10 to the large container 20. For example, the mixture 13 may be transferred from the container 10 installed in the kitchen of each household of the apartment house to the large container 20. The mixture 13 accommodated in each container 10 is during or after aging. Further, the mixture 13 may be transferred by the user of the container 10 or may be recovered by a recovery company or the like. In the mixture 13, the bacteria in the fermenting agent 12 are alive, so that the aging of the mixture 13 continues without adding the fermenting agent 12 just by transferring it to the large container 20, and A state in which the generation of malodor and pests is also maintained. In this way, by transferring the mixture 13 to the large container 20, the meat-based garbage MG can be processed together.

  The large container 20 is the same as the container 10 shown in FIG. 1 except that the capacity is larger than the container 10 as shown in FIG. The large container 20 is a container with a lid 21 having an opening 20a on the upper side and a bottom plate 20b on the lower side. The capacity of the large container 20 is arbitrary as long as it is larger than the capacity of the container 10. For example, the large container 20 having a capacity of several tens of liters can be installed on a veranda or the like. The large container 20 having a capacity of about 100 liters can be installed outdoors such as a home garden. A large container 20 of 1000 liters or more can be used in a compost factory, a collection station, or the like.

  Further, in the same manner as described above, a paper bag 15 or the like containing wood chips 14 or the like is disposed in the large container 20. Thereby, the odor in the large sized container 20 can be deodorized and generation | occurrence | production of a bad odor can be suppressed. Whether or not to arrange the paper bag 15 and the like in the large container 20 is arbitrary.

  Next, the mixture 13 is composted (step S11 in FIG. 4). This step S11 may be performed in the large container 20 as in step S6 of FIG. 2 described above, or may be performed by mixing the mixture 13 and soil, for example. By this step S11, the mixture 13 can be used as compost.

  Further, the composted mixture 13 is transferred to the park 31 or the like (step S12 in FIG. 4). The transfer to the park 31 or the like may be performed when the composting of the mixture 13 is almost completed, or may be performed during the composting of the mixture 13. The composted mixture 13 may be transferred, for example, to the accumulation place of the compost factory 32, the field 33, or the like in addition to the flower bed of the park 31 or the like. However, the transfer destination shown in FIG. 3 is an example and may be another location. Transfer of the mixture 13 may be performed by a trader of the compost factory 32 or a local government. The mixture 13 may be mixed with soil and composted in the park 31 or the like. In the park 31 and the field 33, the composted mixture 13 becomes fertilizer on the spot, which is efficient.

  Next, the composted mixture 13 is processed using earthworms (step S13 in FIG. 4). Earthworms ingest, decompose, and discharge organic matter. By using earthworms, it is possible to produce an ideal organic fertilizer rich in plant nutrients and having the function of a soil conditioner. Any kind of earthworm can be used. As this earthworm, for example, an earthworm (Eisenia fetida) can be used, and a commercially available one can be used. The earthworm is easy to adapt to compost and can produce high quality compost efficiently. In addition, it is arbitrary whether the mixture 13 is processed using earthworms.

  Thus, the meat-based garbage MG can be processed collectively by using the large container 20. In addition, for example, when processing meat-based garbage MG generated in urban areas, compared to the case where it is transported to a distant place by composting in a nearby park 31, school, field, etc., the transportation cost Therefore, it is possible to process garbage at low cost. In this case, the mixture 13 that cannot be processed in a nearby park or the like can be processed in the compost factory 32. Moreover, what cannot be processed in the nearby park 31 etc. or the compost factory 32 can also be carried to the distant field 33 etc. and composted, for example. Thus, according to the garbage processing method of this embodiment, it is possible to efficiently compost meat-based garbage MG generated in urban areas at low cost.

  Next, processing of vegetable-based garbage BG will be described. In this embodiment, the vegetable-based food waste BG is dried to reduce the volume. The vegetable-based garbage BG sorted in step S1 shown in FIG. 2 is accommodated in a container that requires air permeability (step S7 in FIG. 2). The vegetable-based garbage BG may be mainly vegetable-based garbage BG, and may include a little meat-based garbage MG. FIG. 5A is a view showing an example of a container that accommodates vegetable-based garbage BG, and FIG. 5B is a view showing an example of a dryer used for drying vegetable-based garbage BG. As shown in FIG. 5A, the vegetable-based garbage BG is accommodated in a dry basket (container) 40.

  The dry basket 40 includes an upper ring 41, a lower ring 42, a string-like member 43, a net-like body 44, and a hanging string 45. The upper ring 41 and the lower ring 42 are connected by a string-like member 43. The net 44 is attached to the upper ring 41 in an open state. The mesh body 44 ensures air permeability. Moreover, as a container which requires air permeability, for example, a net-like body such as a net or a colander can be used. As the dry basket 40, for example, Japanese Patent Application No. 2014-075156 “garbage dry basket” by the applicant may be used. The dried basket 40 can be hung on an eaves or the like by a hanging string 45 in a state where the vegetable-based garbage BG is accommodated.

  Next, the vegetable-based garbage BG accommodated in the dry basket 40 is sun-dried or put into the dryer 50 and dried to reduce the volume (step S8 in FIG. 2). The vegetable-based garbage BG is in a state in which moisture is removed by sun-drying or the like and composting or incineration is easy. In addition, the volume reduction enables cost reduction such as transportation and storage. The sun drying using the dry basket 40 may be performed, for example, by hanging a hanging string 45 around the eaves.

  When sun-drying outdoors, it should be done in weather other than rainy weather. The vegetable-based garbage BG is dried, for example, so that the weight with respect to the weight before being sun-dried is about 10 to 30%. The time for drying in the sun is set appropriately according to the season and other conditions. For example, in the summer, by performing sundrying for about two days, the weight relative to the weight before sundrying is about 15%. In winter, the sun is dried for about 7 days, so that the weight before the sun is about 15%.

  Further, when the vegetable-based garbage BG is dried by the dryer 50, the vegetable-based garbage BG is put into the dryer 50 while being accommodated in a net bag (container) 53. By using the dryer 50, the drying time of vegetable-based garbage BG can be shortened, and vegetable-based garbage BG can be dried also in rainy weather. As shown in FIG. 5B, the dryer 50 includes a garbage storage unit 51, a fan 52, and the like, and the outside air is introduced by driving the fan 52 and is stored in the garbage storage unit 51. Dry vegetable-based garbage BG. Moreover, the structure of the dryer 50 is arbitrary and various drying apparatuses can be used. For example, Japanese Patent Application No. 2014-034170 “garbage drying apparatus” by the applicant may be used as the dryer 50. Moreover, the dryer 50 may suppress charcoal etc. being disperse | distributed inside and dissipating malodor to the exterior.

  The vegetable-based garbage BG is stored in the net bag 53 and put into the dryer 50. However, the vegetable-based garbage BG may be directly put into the dryer 50 without being stored in the net bag 53 or the like. The net bag 53 is, for example, made of resin or metal, and is one that accommodates vegetable-based garbage BG and whose opening is closed. The illustrated net bag 53 is an example, and the disassembly is arbitrary. The vegetable-based garbage BG has a weight of about 10 to 30% with respect to the weight before drying as in the case of sun-drying by the dryer 50.

  Next, the dried vegetable-based garbage BG is composted or incinerated (step S9 in FIG. 2). The vegetable-based garbage BG is in a state in which moisture is removed and composting or incineration is easy to perform. The method of composting is arbitrary. For example, the vegetable-based garbage GB is composted by mixing dried vegetable-based garbage BG and soil. Similarly to the meat-based garbage MG, the dried vegetable-based garbage BG may be placed on the soil, or the dried vegetable-based garbage BG may be filled in a hole dug in the soil. Moreover, you may perform the process which uses earthworms at the time of composting. Further, similarly to the meat-based garbage MG, the dried vegetable-based garbage BG may be composted by the compost factory building.

  Moreover, the method of incinerating dried vegetable-based garbage BG is arbitrary. Vegetable-based garbage BG can be incinerated by a general incineration method. Further, the dried vegetable-based garbage BG can be collected as combustible waste and can be easily incinerated as normal combustible waste.

  Also, when processing vegetable-based garbage BG generated in urban areas, as with the above-mentioned processing of meat-based garbage MG, composting in nearby parks 31, schools, Noyama, etc., transports it to a distant place. Compared with the case where it carries out, since a transportation cost does not start, it can process at low cost. The vegetable-based garbage BG that cannot be processed in a nearby park may be processed at the compost factory 32. Moreover, what cannot be processed in the nearby park 31 etc. or the compost factory 32 should just be carried to a distant field 33 etc. and composted. Thus, according to the garbage processing method of this embodiment, the vegetable type garbage BG generated in an urban area can be effectively composted at low cost.

  Thus, according to the said method, vegetable type garbage BG can be composted efficiently. In addition, even when the vegetable-based garbage BG is incinerated, the vegetable-based garbage BG can be easily incinerated because the moisture is removed. In addition, in this embodiment, it is arbitrary whether or not the vegetable-based garbage BG is processed. Moreover, vegetable-type garbage BG may be processed by another method. Moreover, the dried vegetable-based garbage BG may be stored for a certain period. The dried vegetable-based garbage BG hardly causes bad odor and can be stored easily.

  The dried vegetable-based garbage BG can be stored for at least about one month, for example, in a paper bag or container so that insects do not enter in order to suppress the generation of pests. This stored product can be composted or incinerated after storage. When the compost factory, local government, or the like performs processing, the stored material may be collected.

  The embodiment has been described above, but the present invention is not limited to the above description, and various modifications can be made without departing from the gist of the present invention.
