2065438+On August 23, 2009, Zhejiang Province issued the Classification Standard of Municipal Domestic Waste, which made it clear that the classification of domestic waste adopted the "four-point method", and it was mainly divided into four categories: recyclable, harmful waste, perishable and other wastes.
Recyclable refers to unpolluted, recyclable and recyclable domestic garbage. Harmful waste refers to the domestic garbage that contains harmful substances and needs special safety treatment. Perishable garbage is perishable and contains organic matter. Other garbage is other domestic garbage except the above three categories.
Large pieces of garbage should be thrown separately, and it is forbidden to mix hazardous wastes. When throwing, it shall not be disassembled or treated in any form. The garden garbage is classified by the operation unit according to the residual branches, fallen leaves, grass clippings, etc., the strip materials are bundled into bundles, and the fragmented materials are packaged into bags; Decoration waste should be classified as recyclable and toxic and harmful.
Extended data:
The advantages of garbage sorting treatment are as follows:
1, reducing land occupation
Some substances in domestic garbage are not easy to degrade, which makes the land seriously eroded. Garbage sorting, removing recyclable and non-degradable substances, reducing the amount of garbage by more than 60%.
Step 2 reduce pollution
At present, sanitary landfill or even simple landfill is mostly used in garbage disposal in China, covering tens of thousands of acres; Moreover, insects and flies fly around, sewage overflows and stinks, which seriously pollutes the environment. Waste plastics in soil will lead to crop yield reduction; Waste plastics are eaten by animals by mistake, resulting in accidents of animal death. So recycling can also reduce the harm.
Step 3 turn waste into treasure
China uses 4 billion plastic fast food boxes, 500-700 million instant noodle bowls and billions of disposable chopsticks every year, accounting for 8- 15% of domestic garbage. 1 ton of waste plastics can recover 600kg of diesel oil. Recycling 1500 tons of waste paper can avoid cutting down trees used to produce 1200 tons of paper. A ton of cans can be melted to form a ton of good aluminum blocks, and 20 tons of aluminum ore can be mined less.
