I. Reuse of livelihood wasteWe produce a lot of livelihood waste every day. If we carry out a simple landfill disposal, the cost of one ton of waste will be 200 to 300 yuan, and it will occupy a lot of land, and it can form land pollution.Livestock waste, such as plastic bottles, cans, old newspapers, glass bottles sold to waste companies, Wuhan waste recovery company and then separated to plastic, metal, paper processing plant, glass factory processing production, can become material from scratch production of various products, in addition to reduce the amount of waste, but also to save material and power.According to the leakage of Qingdao Laoshan Glass Company, after continuous improvement of the use skills of used glass, the utilization rate of the company's recovery of waste glass has risen from 30% at the beginning to 40%, 60% and even 80%.Together, the company can save 4,200 tons of soda soda, 2,108 tons of coal, and 380,000 kilowatt-hours of electricity every year, killing two birds with one stone and saving money.Second, electronic waste is profitableMany valuable metals, such as gold, platinum and indium, can be extracted by discarding electrical appliances.Needless to say, the price of indium, the metal's vitamin, has risen from $70 a kilogram to $1,200.If the waste battery in the old mobile phone is recovered, the accumulation of 1 ton will be able to extract 200 grams of gold, you know, generally gold ore can only extract 2 grams of gold per ton.Currently, e-waste disposal companies in the United States have annual profits of $25 million to $30 million (according to some estimates, an ounce of gold mined costs $300 and an ounce of gold recovered costs only $10).Yongkang, known as the "Hardware Capital" of China, is the largest scrap metal recovery base in China. There are more than 200 scrap metal processing and training companies. The annual turnover of scrap metal reaches 6 to 7 billion yuan, and the production of aluminum alloy is about 250,000 tons.Three, the rich "turn around"The most common and annoying kitchen waste in the home -- leftovers, peels and vegetable leaves -- can be composted "in situ", producing 0.3 tonnes of organic fertilisers per tonne.Much of the combustible waste can be used instead of coal to fuel fires, generate electricity and "heat".France recovers more than 40 million tons of waste each year.20% of the waste, mostly metal, glass and paper, has been recycled.13.5% for compost;29% complete power recovery, that is, for power generation or heat;1.5% for brief combustion;Other wastes are disposed of by harmless storage and landfill.This provides France with 3,700 GWh of electricity and 7,300 GWh of heat, as well as 1.8 million tons of organic fertilizer.Japan currently has a number of waste power plants, and countries such as Denmark and Switzerland burn 80% of their livelihood waste.
