500-word composition on garbage disposal and recycling during the Spring Festival.

Recently, the school launched a "green environmental protection" activity, and the group I participated in decided to carry out research on garbage classification and recycling. First, the status quo survey: In the morning, garbage can be seen everywhere on both sides of the street, some wrapped in plastic bags, some discarded on the ground at will, and some put in trash cans. Passing by the hospital, I went in and saw some expired drugs, discarded mercury thermometers, and some medicine bottles and infusion sets abandoned in the corner of the hospital. These rubbish give off a pungent smell, which makes us afraid to go near. In front of the factory, abandoned batteries, abandoned machines, broken glass and broken boards piled up into mountains. The battery was damaged and the liquid in it leaked out. Waste batteries are called "mini killers". We can imagine how much harm these waste batteries will do to the land after they penetrate into the soil. In the vegetable market, discarded fish and vegetables are piled up on the road at will, and flies are buzzing. This surprised me. Are all the foods you can't buy thrown away at will? A sanitation worker told us that these mountains of garbage were sent to a certain place for landfill treatment. Second, the harm of garbage: it is potentially harmful to dispose of garbage at will. How much land does it take to turn such a large amount of garbage into a landfill? We constantly turn the limited earth resources into garbage, bury or burn them. Where will our descendants live? Classification of garbage disposal: Are we helpless about the pollution of garbage? No, according to our investigation, garbage can be generally divided into four categories: recyclable garbage, kitchen waste, harmful waste and other garbage. The recovered garbage can be directly sent to relevant factories for reprocessing and waste utilization. For example: 1 ton of paper can be recycled into 800 kilograms of good paper; Rare metals such as zinc, copper and manganese dioxide can be extracted from recycled batteries; The recycled waste plastics can be recycled into fuel. Kitchen waste, such as leftover lettuce, eggshell skin, cabbage leaves, etc. You can pile up the waste, corrupt the fiber and organic matter of the waste and turn it into fertilizer to improve the soil. In harmful waste, such as waste fluorescent tubes, expired drugs, etc., can be burned together, so as to minimize the harm of garbage. Other garbage that is difficult to recycle and harmless to the environment, such as ceramics and dregs, can be effectively landfilled to reduce the pollution of groundwater, soil and air. Fourth, our suggestion: 1, let people understand the importance of garbage classification through publicity; 2. Set up sorting bins in residential areas, vegetable markets, hospitals, factories and other places to facilitate sanitation workers to sort all kinds of garbage. Garbage is a public hazard, but as long as we use the method of garbage classification to deal with it, we can completely turn garbage from enemies into friends.
