Rock wool is a product made mainly of high-quality basalt, dolomite, and other raw materials, with an appropriate amount of binders and additives added. It is manufactured under high temperature and pressure and can be made into felt, strip, tube, granular, plate and other forms according to different purposes. It is used in industrial, construction, shipbuilding, and agricultural fields such as nuclear power plants, power plants, large kilns, external insulation of building walls, isolation belts, cabins, and factory soilless cultivation.
During the production and use of rock wool, a large amount of rock wool waste is generated. Like other waste materials, unreasonable treatment methods can easily lead to environmental pollution caused by rock wool waste, such as soil and water pollution during landfilling, air pollution and noise pollution during cutting, etc. Similarly, reasonable recycling and utilization can achieve the resource utilization of rock wool waste, such as reapplying it to the construction industry to exert its insulation, sound insulation, and sound absorption properties, and applying it to high-temperature furnaces and kilns as refractory materials.
So what are the disposal methods for rock wool waste?
- Landfill treatment: For rock wool waste with limited treatment methods, difficulty in treatment, or high treatment costs, landfill treatment can be carried out at the landfill site.
- Incineration treatment: For rock wool waste that cannot be recovered and treated, reactors, pyrolysis devices, etc. can be used for high-temperature incineration, and harmful substances can be decomposed and harmless treated at high temperatures.
- Chemical treatment: There are some harmful substances in rock wool waste, such as nitrite, which need to be treated with chemical methods before resource utilization.
- Physical treatment: By using processes such as crushing, screening, and sorting, impurities in rock wool waste can be effectively removed, and the size can be reduced for further resource utilization and disposal.
