這些垃圾通過綜合處理回收利用，可以減少污染，節省資源。如每回收1噸廢紙可造好紙850公斤，節省木材300公斤，比等量生產減少污染74%；每回收1噸塑料飲料瓶可獲得0.7噸二級原料；每回收1噸廢鋼鐵可煉好鋼0.9噸，比用礦石冶煉節約成本47%，減少空氣污染75%，減少97%的水污染和固體廢物。
Through comprehensive treatment and recycling, these wastes can reduce pollution and save resources. For example, each ton of waste paper recovered can produce 850 kg of paper, save 300 kg of wood, and reduce pollution by 74% compared with the same amount of production; 0.7 tons of secondary raw materials can be obtained for each ton of plastic beverage bottle recycled; For every ton of waste steel recovered, 0.9 tons of steel can be refined, which saves 47% of the cost compared with ore smelting, reduces 75% of air pollution and 97% of water pollution and solid waste.
