Waste sorting system manufacturer believes that material recycling can save energy and protect the environment and prevent excessive consumption burden on the planet.
If there is no material recovery, we will waste more power in the production of new products. The role of material recovery and reuse cannot be replaced by any other industry. The economically prosperous country regards the material recycling industry as a rising industry. With the rapid development of China's economy, the improvement of skills, and the slowdown of upgrading, more and more products will lose their use value and become waste products, entering the stage of recycling and reuse of waste products. Therefore, the waste to energy system makes effective use of useful resources, proper treatment of harmful resources, and prevention of purification of the environment become very important.
The Waste To Energy System
Application value: For each ton of scrap steel recovered, 850 kg of steel can be produced. Compared with iron ore, steel can save 20 tons of iron ore and save 1.2 tons of standard coal. Recycling and applying 1 ton of waste paper can make 800 kilograms of good paper, save 17 big trees, use 240 kilograms of soda ash, reduce papermaking purification emissions by 75%, and save papermaking power consumption by 40-50% The value of waste plastics: By recovering waste plastics into gasoline and diesel, more than 700 liters of unleaded gasoline and diesel can be consumed from one ton of waste plastic. The value of waste cans: cans can be recycled into new cans in countless 100% cycles after dissolution, and can also be made into automobile, aircraft parts, or furniture. The value of waste glass: 20,000 500 g bottles can be consumed after 1 ton of waste glass is returned to the furnace. Consumption is 20% cheaper than using new raw materials. Recycling 1 ton of waste glass can save 720 kg of quartz sand, 250 kg of soda ash, 60 kg of feldspar powder, 10 tons of coal, and 400 degrees of electricity.
I. Reuse of livelihood waste
We are making a lot of livelihood waste every day. If we carry out 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 cause land pollution. Livelihood wastes, such as plastic bottles, cans, old newspapers, and glass bottles, are sold to waste companies. Wuhan waste recycling companies can then be sent to plastic, metal, paper processing plants, and glass factories for processing and production. In addition to reducing the amount of waste, it also saves material and power. According to a leak from Qingdao Laoshan Glass Company, after continuously reforming the skills of using waste glass, the company's recovery rate of waste glass has now increased from 30% to 40%, 60% and even 80%. Together, the company can save 4,200 tons of soda ash, 2108 tons of coal, and 380,000 kWh of electricity each year. This saves money and protects the environment, killing two birds with one stone.
Profit from e-waste
Discarding electrical appliances can extract many valuable metals, such as gold, platinum, and indium. Needless to say, gold and platinum, indium is called a metal vitamin, and its price has now risen from $ 70 to $ 1,200 per kilogram. If the used batteries in the old mobile phone are recovered, 200 grams of gold can be refined by accumulating 1 ton. You must know that generally only 2 grams of gold can be extracted per ton of gold-containing ore. At present, the annual profit of US electronic waste disposal companies has reached 25-30 million US dollars (according to statistics, it takes US $ 300 to mine one ounce of gold and only US $ 10 to recover one ounce of gold). Known as China's "Hardware Capital", Yongkang is currently the largest domestic scrap metal recovery base. There are more than 200 scrap metal processing and exercise companies. The annual turnover of scrap metal is 6 billion to 7 billion yuan, and 250,000 aluminum alloys are produced. Tons or so.
Third, rich "turn around"
The most common and most annoying kitchen waste in the family, leftovers, leftovers, peeled vegetables and leaves, can be disposed of in-situ by biological skills, which can produce 0.3 tons of organic fertilizer per ton. Many combustible wastes can "substitute" coal into fires, generate electricity and generate "heat". France can recover more than 40 million tons of waste each year. During the period, 20% of the waste was recycled and reused, mostly metal, glass, and paper; 13.5% was used for composting; 29% was recovered for power, that is, used for power generation or heat generation; 1.5% was simply burned; other waste Dispose of by harmless storage and landfill. This provided 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 multiple waste-to-energy plants, and the livelihood waste burning rate in Denmark and Switzerland has reached 80%.
