Questions and answers about garbage classification
Each of us throws a lot of rubbish every day. Do you know where all this rubbish has gone? In some areas with good garbage management, most of the garbage will be treated harmlessly, such as sanitary landfill, incineration and composting. In more places, garbage is often simply piled up or buried, which leads to stinking and pollutes soil and groundwater. The cost of harmless treatment of garbage is very high. According to the different treatment methods, the cost of treating one ton of garbage is about one hundred to several hundred yuan. People consume a lot of resources, produce a lot, consume a lot and produce a lot of garbage.
How to turn harm into benefit, turn waste into treasure and save energy? There is a way, and that is garbage sorting. Garbage classification is to put garbage into the source, and make it become a resource again through sorting, cleaning and recycling.
Generally speaking, domestic garbage in Guangzhou can be divided into four categories: recyclable garbage, kitchen waste, harmful waste and other garbage. At present, the commonly used garbage disposal methods mainly include comprehensive utilization, sanitary landfill, incineration for power generation, composting and resource reuse.
(1) Recyclable garbage: It mainly includes five categories: waste paper, plastic, glass, metal and cloth.
1. Waste paper: it mainly includes newspapers, periodicals, books, all kinds of wrapping paper, office paper, advertising paper, cartons, etc. However, it should be noted that paper towels and toilet paper are too water-soluble to be recycled.
2. Plastics: mainly including various plastic bags, plastic packaging, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, toothpaste tubes, etc.
3. Glass: mainly includes various glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles, etc.
4. Metal objects: mainly include cans and cans.
5. Cloth: mainly includes discarded clothes, tablecloths, towels, schoolbags, shoes, etc.
Through the comprehensive treatment and recovery of recyclable garbage, pollution is reduced and resources are saved. If every 1 ton of waste paper is recycled, 850 kilograms of paper can be made, 300 kilograms of wood can be saved, and pollution is reduced by 74% compared with the same output; Every 1 ton plastic beverage bottle can recover 0.7 tons of secondary raw materials; Every recovered 1 ton of scrap steel can produce 0.9 tons of steel, which saves 47% cost compared with ore smelting, reduces air pollution by 75%, and reduces water pollution and solid waste by 97%.
(2) Kitchen waste: including food waste such as leftovers, bones, roots, leaves and peels. This kind of waste can be composted in situ by biotechnology, and 0.3 tons of organic fertilizer can be produced per ton.
(3) Hazardous wastes: including waste batteries, waste fluorescent tubes, waste water silver thermometers, expired drugs, etc. These wastes need special safety treatment to avoid harm to the environment.
(4) Other wastes: including bricks and tiles, waste residue, toilet waste paper, paper towels and other wastes that are difficult to recycle, and are usually disposed by incineration or landfill according to the characteristics of wastes.
20 1 1 April, Guangzhou officially implemented the Interim Provisions on the Management of Urban Domestic Waste Classification (hereinafter referred to as the "Regulations"), and the classification of domestic waste finally has rules to follow. The "Regulations" implement the principle of "easy before difficult, step by step, step by step". Firstly, the kitchen waste is classified, and then other wastes are further subdivided step by step. The regulations also stipulate the amount of fines. It is understood that individuals who refuse to make corrections after being ordered to put municipal solid waste in accordance with regulations will be fined 50 yuan each time, and those who fail to put municipal solid waste in accordance with regulations will be fined 500 yuan per cubic meter. The classified recycling of campus garbage can greatly reduce the pollution caused by the increase of garbage, save the cost of harmless treatment of garbage, and be conducive to the reuse of resources. Last year, our school also bought more trash cans with garbage classification signs, and carried out garbage classification and recycling activities on campus. Through this series of activities, we can not only save resources, but also cultivate teachers and students' awareness of environmental protection. Let's act together, popularize and popularize the knowledge of garbage classification, deal with garbage according to the requirements of garbage classification, and build a harmonious, beautiful and economical campus.
