At present, China's domestic waste treatment is mainly based on sanitary landfill, and the classification and subdivision of waste are not strong, without forming an effective recycling model. Harmless disposal of garbage refers to the harmless or safe treatment of harmful biological or chemical substances in waste.

In the first half of 2014, the asset scale of China's waste resources and waste materials recycling and processing industry reached 156.373 billion yuan, a year-on-year increase of 25.4%. The sales scale of the waste resources and waste materials recycling and processing industry reached 394.842 billion yuan, a year-on-year increase of 24.7%. The total profit of the waste resources and waste materials recycling and processing industry was 44.738 billion yuan, a year-on-year increase of 78.6% The "Twelfth Five Year Plan" National Plan for the Construction of Facilities for Harmless Treatment of detoxification of municipal solid waste proposes that by 2015, all domestic waste in municipalities directly under the Central Government, provincial capitals and cities specifically designated in the plan will be treated harmlessly. The rate of harmless treatment of domestic waste in cities with cities will reach more than 90%. The counties and counties will have the capacity for harmless treatment of waste. The rate of harmless treatment of domestic waste in county towns will reach more than 70%. The capacity of new facilities for harmless treatment of domestic waste in cities and towns nationwide will reach 580000 tons/day. By 2015, the capacity of urban domestic waste incineration facilities in China will reach over 35% of the total harmless treatment capacity, with the eastern region reaching over 48%, and a sound urban domestic waste treatment supervision system will be established.

At present, there are over 1600 county-level towns in China, and according to national planning and deployment, they will gradually carry out harmless treatment of garbage, with considerable development potential. In terms of waste disposal methods, China mainly relies on landfill, incineration, and composting. Landfilling is currently the main method, accounting for nearly half of the total; Burning accounts for about 12%; Composting less than 10%; 30% of the garbage is still not well disposed of. According to estimates, one-third of cities in China are currently surrounded by garbage, with a cumulative accumulation of over 7 billion tons of garbage and occupying more than 800000 acres of land, indicating the urgent need for harmless disposal of garbage. Therefore, China has increased investment in the harmless treatment of garbage. According to the 12th Five Year Plan, the total investment in environmental protection exceeds 3.4 trillion yuan, of which the total investment in solid waste exceeds 800 billion yuan, and the investment in garbage disposal facilities in solid waste investment exceeds 263.6 billion yuan.

In recent years, China's capacity for handling household waste has greatly improved. In 2013, the amount of municipal solid waste cleared in China was 173 million tons, with a harmless treatment capacity of 493000 tons per day and a harmless treatment capacity of 154 million tons, resulting in a harmless treatment rate of 89.0%.
