The construction waste heap mountain landscaping utilization mode needs to occupy a large amount of land and has no durability. A large amount of kitchen waste is not utilized basically, or enters the illegal feeding field, or is discharged directly. Industrial hazardous solid waste poses great harm to the environment and needs to be properly and safely disposed. The sludge causes the blockage of the river channel and the water quality is reduced. A green building material recycling industrial park is built, urban garbage is treated in a centralized mode, recycling and gradient utilization of resource and energy are achieved, the environmental problem is solved, recycling of waste is achieved, and the method becomes an important way for solving urban solid waste.
The currently established circular industrial park in China breaks through the traditional solid waste disposal industrial mode and provides effective demonstration in the aspects of park construction, park treatment and comprehensive energy utilization. Taking the environment-friendly industrial park of the south China Foshan sea for solid wastes as an example, the park takes waste incineration as a center, a complete industrial chain from source to terminal is formed, and the solid wastes are subjected to 100% synergistic treatment. The cement kiln cooperative treatment has a strong development trend in recent years due to the advantages of low investment, large treatment capacity, good treatment effect and the like. It can be seen from the market promotion degree that the combination of the solid waste industry and the cement kiln has no barrier in the aspects of technical maturity and implementation feasibility. The domestic green building material circulation industrial park taking the cement kiln as the center has been partially researched, but the production mode is not comprehensive. If the green building material recycling industrial park is effectively implemented and popularized, the method can bring remarkable effects to the development of regional economy and social environmental benefits.
