What is the significance of garbage classification?

The purpose of garbage classification

1. Garbage classification is an important part of the front-end processing of domestic waste. 2. Through garbage classification and collection, useful materials such as paper, plastic, rubber, glass, metal, and used household appliances are separated from domestic garbage, recycled, classified, fully utilized, and turned into treasure. It can not only improve the resource utilization level of domestic waste, but also reduce the amount of waste disposal. This is an effective way and means to reduce domestic waste.

2. Garbage classification collection is conducive to the classification and processing of different types of domestic waste, such as composting organic domestic waste, making organic domestic waste into farmland fertilizer or green fertilizer; landfilling inorganic waste with no recycling value Domestic waste; incinerate combustible domestic waste with high calorific value. Garbage classification collection and processing is a reform of the traditional domestic garbage collection and processing method. It is a scientific management method to effectively deal with domestic waste. Faced with the increasingly prominent amount of domestic waste and the rapidly deteriorating environmental conditions, how to maximize the use of domestic waste resources, reduce the amount of waste disposal through waste classification management, and effectively improve the quality of life is an urgent issue of common concern to all countries in the world. one.

Benefits of waste classification 1. Reduce land occupation: Certain substances in domestic waste are not easily degraded, causing land erosion. After implementing waste classification and removing non-degradable substances that can be recycled and processed, the amount of domestic waste can be reduced by more than 50%

2. Reduce environmental pollution: Waste batteries contain toxic substances such as metallic mercury and cadmium, which are harmful to the environment. Causes harm; waste plastic in soil can reduce crop yields. Recycling can reuse the above materials and reduce environmental pollution. 3. Turn waste into treasure: 1 ton of waste plastic can recycle 600 kilograms of unleaded gasoline or diesel. 1,500 tons of waste paper will be recycled and sorted to avoid cutting down the trees used to produce 1,200 tons of paper. After melting, a ton of cans can be turned into a ton of very good aluminum nuggets, which can reduce the amount of aluminum ore mined by 20 tons. Waste classification and recycling can be reused, turning waste into treasure. Recycling of recyclable materials and reuse of valuable waste paper: Recycling can reuse 1 ton of waste paper, which can regenerate 800 kilograms of good paper, save 17 big trees, save 3 cubic meters of space in the waste treatment plant, and use 240 less Kilogram of soda ash reduces 75% of papermaking pollution emissions and saves 40% to 50% of papermaking energy consumption. Every piece of paper can be recycled and sorted at least twice.

In addition, the waste fabrics we discard daily can also be used for recycling, sorting, paper making, etc. Waste Plastic: Plastic comes from the earth’s non-renewable resource – petroleum. Recycling and sorting waste plastics is about saving oil. All waste plastics, waste lunch boxes, food packaging bags, flexible packaging boxes, etc. can be recycled into fuel by making full use of the technology of reducing waste plastics into gasoline and diesel. One ton of waste plastic can produce 700 to 750 liters of unleaded gasoline or diesel. Many waste plastics can also be reduced to recyclable plastics, which can be recycled up to ten times more often. Waste glass: Recycling of 1 ton of waste glass saves 20% of the cost compared to making full use of new raw materials. Recycling one ton of waste glass can save 720 kilograms of quartz sand, 250 kilograms of soda ash, 60 kilograms of feldspar powder, 10 tons of coal and 400 kilowatt hours of electricity. Aluminum Can Scrap: After dissolving, scrap cans can be recycled countless times to create new cans. In addition, they can be made into parts for cars, airplanes and even furniture. Recycling aluminum cans saves 95% of the energy required for new aluminum cans and reduces air pollution by 95%.

Organic matter: More than 40% of the garbage we throw out from home every day is kitchen waste, such as fruit peels, eggshells, vegetable leaves and leftovers. These wastes can be processed as organic fertilizers or feed additives through composting and fermentation. Waste batteries: Mercury and cadmium in waste batteries are highly polluting and toxic heavy metals. Recycling batteries can extract metals such as zinc, copper and manganese
