Among conventional energy sources, coal is the largest energy source in China. What pollution does recycling easily produce?

85% of the coal in China is directly burned, mainly including thermal power generation, industrial boiler (kiln) furnace, civil heating and household stoves. Coal burning with high consumption and low efficiency releases a lot of SO2, CO2 and smoke into the air, which causes air pollution in China, mainly in the form of smoke.

(1) Coal mining leads to the destruction of land resources and the deterioration of ecological environment. Due to stripping and dumping of open-pit mining, surface subsidence and cracks in underground mining will destroy land resources and plant resources, affect land cultivation and vegetation growth, change landforms and cause changes in landscape ecology. (2) Coal mining destroys groundwater resources and intensifies water shortage in water-deficient areas. China is a country with low per capita water resources in the world, and the distribution of water resources is extremely unbalanced. (3) Coal mining leads to waste gas emission and harms the atmospheric environment. The waste gas formed by coal mining mainly refers to mine gas and gas released by spontaneous combustion of ground waste hills.
