Live garbage is classified in accordance with the following requirements:
(a) recyclables, is suitable for recovery and recyclable waste paper, plastics, metals, textiles, electronic and electrical appliances, glass, wood and other waste materials;
(b) hazardous garbage, refers to the human health, the natural environment caused by direct or potential hazards of the discarded batteries, fluorescent tubes, thermometers, sphygmomanometers, medicines, paints, solvents, chemical pesticides, disinfectants, film and photographic paper and other substances;
(iii) perishable garbage, refers to engaged in catering services, collective feeding, food processing and other activities generated by the kitchen waste, food waste generated by the residents of the household, the market, the operation of fresh supermarkets generated by the discarded vegetables, fruits and vegetables, and other organic, perishable substances;
(d) bulky garbage, refers to the overall strong, need to be disassembled and processed, weighing more than 5 kg or volume of more than 0.2 cubic meters or length of more than 1 meter of solid waste;
(e) other garbage, refers to other than the first four items of the need for environmentally sound treatment of domestic garbage.
The classification of garbage is a general term for a series of activities to separate garbage for storage, placement and transportation according to certain regulations or standards, so as to transform it into public **** resources. The purpose of classification is to improve the resource value and economic value of garbage, strive to make the best use of things, reduce the amount of garbage disposal and treatment equipment, reduce the cost of treatment, reduce the consumption of land resources, with social, economic, ecological and other aspects of the benefits.
The garbage belongs to the public's private goods at the stage of classification and storage, the garbage becomes a regional quasi-public **** resource in the public's neighborhood or community after the public classification and placement, and the garbage becomes a public **** resource without exclusion after the garbage is classified and carried to the garbage centralized point or transfer station. From the domestic and foreign cities on the classification of domestic garbage method, most of them are based on the composition of the garbage, the amount of production, combined with the local garbage resource utilization and treatment methods, etc. to classify.
The advantages of garbage classification are as follows:
Reducing land erosion
Some substances in domestic garbage are not easy to be degraded, which makes the land seriously eroded. Separating garbage and removing recyclable and not easily degradable substances reduces the amount of garbage by more than 60%.
Reducing Pollution
China's garbage disposal mostly adopts sanitary landfills or even simple landfills, which occupy tens of thousands of acres of land; moreover, the insects and flies fly about, the sewage overflows, and the stench is so strong that it seriously pollutes the environment.
The waste plastics in the soil will lead to crop yield reduction; abandoned waste plastics are accidentally eaten by animals, resulting in animal deaths from time to time. Therefore recycling can also reduce the harm.
Turning waste into treasure
China's annual use of plastic fast-food containers amounted to 4 billion, instant noodle bowls 500-700 million, billions of pairs of disposable chopsticks, which accounted for 8-15% of the household garbage. 1 ton of waste plastic can be smelted back to 600 kilograms of diesel fuel. Recycling 1,500 tons of waste paper can avoid cutting down forests used to produce 1,200 tons of paper. One ton of cans can be melted to form one ton of very good aluminum blocks, which can reduce the mining of 20 tons of aluminum ore. 30% to 40% of household waste can be recycled, and this small, profitable resource should be treasured. We can also use cans to make pencil cases, both environmental protection, but also save resources.
And, other substances in the garbage can also be converted into resources, such as food, grass and fabrics can be composted to produce organic fertilizer; garbage incineration can be used to generate electricity, heating or refrigeration; bricks, tiles and ash can be processed into building materials and so on. If the resource potential contained in recycled domestic waste can be fully tapped. It can be seen that the consumption of waste generated by the link if the timely classification, recycling and reuse is the best way to solve the garbage problem.
Legal basis:
"Fuzhou City, the management of classification of household garbage"
Article 1 in order to strengthen the management of classification of household garbage, to improve the reduction of household garbage, resources, harmlessness, to improve the ecological environment in urban and rural areas, and to promote the sustainable economic and social development, and to promote the construction of an ecological civilization, according to relevant laws, Regulations, combined with the actual situation in the city, the formulation of these measures.
