据抽样调查和统计,在城市生活垃圾中,生物垃圾占31.8％,塑料、纸类、纺织品、金属、木制品、玻璃加在一起占36.1％,这些垃圾如能做到分类回收,可将城市生活中的垃圾量减少到三分之一,既可减轻环境污染,又可做到废物利用,一举两得。 有关调查表明,回收一吨废纸可再造800公斤好纸,挽救17棵大树;菜叶、果皮等生物垃圾可再生利用为绿色肥料;每吨废塑料可回炼出600公斤铅汽油和柴油;废电池堆放在自然界是有毒污染物,但回收起来却是宝贵的稀有金属…… 垃圾分类和回收意义重大,目前由于回收渠道不
According to sample surveys and statistics, 31.8% of municipal solid waste, 31.8% of biological waste, plastics, paper, textiles, metals, wood products, and glass together account for 36.1%. If these garbage can be recycled, they can The amount of garbage in life is reduced to one-third, which can reduce environmental pollution and make use of waste. Relevant investigation shows that recycling one ton of waste paper can recreate 800 kilograms of good paper and save 17 large trees; biological waste such as leaves and peels can be recycled and used as green fertilizer; 600 kilograms of lead gasoline and diesel can be recycled per ton of waste plastics. Waste batteries are toxic contaminants in nature, but they are precious metals that are recycled.... Garbage classification and recycling are of great significance. Currently, recycling channels are not
