Incineration and accidental fires can create corrosive byproducts like hydrochloric acid and hydrofluoric acid and poisons like halogenated dioxins and furans.
To improve environmental quality, the city added nine sewage treatment plants, dredged 290 km of waterways and built waste incineration and wind power generation facilities.
Landfill operators who also use their site for recycling, incineration or sorting waste can apply to have the relevant area designated a tax-free site.
After considering the effects of air pollution on the environment and public health, it was decided to cease using incineration to dispose of solid waste.
