It is said that the judgment should be made by comprehensively considering the properties, the status of discharge, the normal handling form, the existence of transaction value, the intention of the occupant, etc.[4].

According to the Resource Conservation and Recovery Act (RCRA), "waste" means "waste is any waste or waste discharged from waste treatment facilities, waterworks facilities or air pollution control facilities. And sludge and other wastes containing solid, liquid, semi-solid and gaseous substances resulting from industrial, commercial, mining, agricultural business and community activities. "[6]..However, "solid and soluble substances in domestic wastewater, solid and soluble substances in irrigation wastewater, points requiring a discharge permit under Article 42 of the Federal Water Pollution Control Law, factory wastewater, which is a pollution source, or the Nuclear Energy Act of 1954. Does not include defined radiation sources, specific radioactive substances or by-products. "[6].

Chinese law

In China, "solid waste" is used as a word equivalent to "waste" in Japan. According to Article 3 of the "Solid Waste Environmental Pollution Control Law", "waste" is "utility value". There is no definition of "living waste" or "industrial solid waste", which is similar to the classification of general waste and industrial waste in Japan. In particular, it can be seen that "dangerous waste" is roughly classified into three defined in parallel.[7].

Waste disposal

Under the Basel Convention, "treatment" of waste refers to the collection, transportation and disposal of hazardous waste or other waste, including the ex post facto management of the disposal site.[1].

Waste in Japan


According to the Waste Disposal and Public Cleansing Law (Waste Management Law), waste is first treated.Industrial wasteGeneral wasteBroadly divided into[6].


Amount of waste in the first year of Reiwa
  • Industrial waste
    • Total emissions of about 3 tons[8]
    • Recycling amount of about 2 tons[8]
    • Weight reduction amount of about 1 tons [8]
    • Final disposal amount of about 915.7 million tons[8]
  • General waste
    • Total emissions of about 4,274 million tons[9]
    • Total resource recovery amount of about 840 million tons[9]
    • Final disposal amount of about 380 million tons[9]

Landfill wasteFinal disposal siteAlthough the number of remaining years is generally increasing, the situation is still severe in the Tokyo metropolitan area, which is 2019 years (4 years nationwide) as of April 6.5.In addition, the number of final disposal sites is generally on a downward trend, and securing final disposal sites remains difficult.[10]..As of the end of the 2nd year of Reiwa, there are 1,602 final disposal sites for general waste (including 2 new facilities during the 15nd year of Reiwa, including 9 facilities before operation), and a residual capacity of 99,836 m3, 28. Since the fiscal year, it has been around 1 million m3.The national average of the remaining years is 22.4 years, and it has been around 29 years since 22.Regarding the situation of the remaining years in the metropolitan area,Capital AreaThen in 28.2,Kinki areaThen it was 19.1[11].

In addition, although it is on a downward trend, the amount of food waste is often a problem.Food waste is thrown away even though it was originally eaten in the first year of Reiwa.Food lossWas estimated to be about 570 million tons.The breakdown was 309 million tons from business and 261 million tons from households.[12].

Waste in the United States


Under the Resource Conservation and Recovery Act (RCRA), waste is first roughly divided into hazardous waste and non-hazardous waste.[6].

Hazardous waste is "depending on its amount, concentration or physical, chemical or infectious nature (A) increased mortality or irreparable severe illness or part of its function. Waste or waste that gives an important factor in the increase of illnesses such as loss of waste, or (B) poses a danger now or in the future due to improper disposal, storage, transportation or disposal. It refers to a mixture. "[6]..Non-hazardous waste has a subtitle in the Resource Conservation and Restoration Law, but is not defined. It is defined as "waste that is not physical waste and is generated during the manufacturing and production process."[6].

Each state

Once the state's waste treatment plan is approved by the Federal Environmental Protection Agency, the state government will be the main body responsible for establishing and managing waste treatment rules.[6]..Waste classification and guidance also varies from state to state, and the Federal Environmental Protection Agency distinguishes between commercial waste and industrial waste, but some states do not.[6].

Private consignment

Regarding waste treatment, public involvement in collection and disposal excluding planning and evaluation has diminished, and there is a strong tendency to entrust it to private companies.[6]..Due to the financial crisis and the shortage of landfill sites, New York City has closed a public landfill site and outsourced the collection and disposal of waste to a private company.[6].

Waste in China


Under the "Solid Waste Environmental Pollution Control Law," waste is roughly classified into "living waste," "industrial solid waste," and "hazardous waste."[7].

In fact, at the 2017 National People's Congress, "disseminating the waste separation disposal system" was mentioned as an important issue.[13]..In China, waste separation will be tried for the first time in 2018 priority cities such as Beijing, Tianjin, and Guangzhou from 46, and from 2019, municipal waste (equivalent to Japanese prefecture) and higher cities will be used for living waste. Sorting work has started completely[13].. By the end of 2020, 46 priority cities will be ready for sorting.Among them, the "Shanghai City Garbage Management Ordinance," which is said to be "the strictest sorting regulation in China," came into effect on July 7 in Shanghai.[13].

Case study in Shanghai

According to the "Shanghai City Waste Management Ordinance," household waste is "recycled resources" (cans, bottles, clothing, plastics, etc.), "harmful waste" (batteries, fluorescent lamps, etc.), and "wet waste (wet waste)" ( We will separate the garbage into four types: "garbage" and "dry garbage" (dirty paper scraps, diapers, and other garbage), and will dispose of the garbage "at the designated place at the designated time".[14].

According to the report of the city government in November 2019, the collected recycled resources were about 11 tons / day and the wet garbage (swill) was about 3 tons / day in the three months after the enforcement, October 5960. Compared to, it increased by 8710 times and 2018 times, respectively.[14]..In addition, dry waste is 14,830 tons / day (down 33% from the same month), and harmful waste is 1 ton / day (more than 10 times the same month).[14].
