In the production of rock wool board, the rock wool quilt containing more slag balls is removed to become waste rock wool slag. The molten waste glass body is also one of the waste slag wastes in the production process of rock wool. Because of the difficult degradation and environmental pollution, most of these wastes are dumped and buried. The amount of waste slag is less than several thousand tons and tens of thousands of tons every year. Dumping and burying not only wastes manpower and transportation capacity, but also Facing great pressure of environmental protection. In the face of various pressures of social environment and national policies, perhaps many rock wool production enterprises do not know what to do?
Using the special equipment to treat the rock wool waste in the brick factory can not only reduce the labor cost and freight cost of dumping and burying, but also increase tens of thousands of tons of raw materials every year and reduce the quantity of purchased raw materials. It is the best choice for rock wool, mineral wool and other waste enterprises. However, the best place to go is to recycle the rock wool slag. The recycling of waste residue is beneficial to the country and the people. At the same time, it can enjoy all kinds of tax preferences and government subsidies for clean production of solid waste treatment and recycling. Environment, enterprise and government achieve three wins.
These rock wool, mineral wool, glass wool waste pellets and waste residues are recycled to make new rock wool and mineral wool products, which greatly reduces the output of rock wool enterprise waste residue. At the same time, the waste rock wool can still be recycled. For example, it costs 3 million to process 10000 tons of waste pellets and waste residues a year. Recycle and realize zero discharge of waste residue. It will regenerate thousands to 10000 tons of new rock wool, mineral wool products. That is to say, it will cost 300 RMB per ton for non treatment. After regeneration, these wastes will become new rock wool products of 2000 RMB per ton, with high added value. It not only realizes the utilization of solid wastes, improves profits, but also realizes the clean production of circular economy, saves land, and also obtains various tax concessions, with no harm.
