Industry Prospects for Comprehensive Utilization of Industrial Solid Waste

2022-06-21

At present, most of the solid waste industries are concentrated in heavy industries such as iron and steel, non-ferrous metals, power generation, chemical industry, and mining industries such as coal and minerals. Fly ash, industrial by-product gypsum, carbide slag, etc.

If these solid wastes are not treated in time, they will not only cause serious pollution, but also cause serious waste of resources. Therefore, how to deal with industrial solid wastes in an environmentally friendly manner and improve the comprehensive utilization rate of resources is an urgent problem to be solved at present.

The development, popularization and application of advanced processes, technologies and equipment have solved some technical bottlenecks and problems in the recycling of industrial solid waste. According to statistics, the current key area of ​​industrial solid waste consumption and utilization in my country is the building materials industry.

Taking the cement industry as an example, the current total annual output of cement in my country has reached 2.5 billion tons. On average, 20% of the waste residue is added as a mixed material, which can consume 500 million tons of industrial solid waste annually.

It can be seen that for the building materials industry, solid waste is a “misplaced resource” and a “gold mine” of building materials resources.
