For example, each recycled 1 ton of waste paper can make good paper 850 kilograms, saving 300 kilograms of wood, than the same amount of production to reduce pollution by 74%.
Each recycled 1 ton of plastic beverage bottles can be obtained 0.7 tons of secondary raw materials; each recycled 1 ton of scrap steel can be refined 0.9 tons of steel, smelting than with ore to save 47% of the cost of 75% reduction in air pollution, 97% reduction in water pollution and solid waste.
2, kitchen waste, including leftovers, bones, vegetable roots and leaves and other food waste, made of biotechnology compost, each ton can produce 0.3 tons of organic fertilizer.

China Municipal Waste Treatment The technical countermeasures are: sanitary landfill and high-temperature composting technologies are the main ones, and incineration technologies are advocated to be developed in cities with conditions, especially in economically developed coastal areas.
Cities began to carry out basic and applied research on garbage incineration treatment, and developed a number of small garbage combustion furnaces, including the NF series of reverse combustion, RF series of pyrolysis, HL series of rotary small garbage combustion furnace and a number of special incinerators for hospital garbage and built a number of small and medium-sized city simple incineration plants (stations).
In 1985, Shenzhen, the introduction of Japan's Mitsubishi incineration of complete sets of technology and equipment, built China's first large-scale (300t / d) modern waste incineration and power generation integrated treatment plant, for China to carry out the work of localization of municipal waste incineration equipment to lay the foundation.
