Why to recycle the municipal solid waste!

According to the statistics from Beijing Environmental Protection Fund, the annual garbage output of Beijing(AGOB) includes 362,000 tons waste plastics. Since 0.37 to 0.73 ton oil can be generated from 1 ton waste plastics, a profit of 8,000 yuan could be made by recycling 1 ton beverage-bottle plastics. Besides, AGOB contains 38.8 tons waste paper. 1 ton waste paper can be reproduced into 0.85 ton qualified paper. At the same time, 3 m?woods and 300 kg alkali could be conserved. 74% pollution could be reduced as well, comparing with producing equivalent good paper by traditional methods. Moreover, there is 15 tons cullet in AGOB. Reproducing glass from cullet could conserve 10%-30% energy, and reduce 20% air pollution and 80% mineral waste residue. In addition, AGOB has 0.237 billion used batteries, from which valuable heavy metal could be regenerated, such as Cadmium, Nickel, Manganese, Zinc, etc.. Simultaneously the heavy metal?potential harm on environment and human health can be reduced. Furthermore, AGOB comprises 35,000 tons scrap metal. 0.9 ton qualified steel can be made from 1 ton ferrous waste; thus, 75% air pollution, 97% water pollution and solid waste can be reduced and 47% cost can be cut, comparing with producing steel from ore. What more, AGOB contains 1,213,000 tons food and vegetation waste. 0.6 ton organic fertilizer can be generated from 1 ton food and vegetation waste. This kind of trash can also be processed into fuel, which is useful in electricity generation and heat addition.
