据统计,2011年至今,全国岩棉已建和在建生产线在40条左右,产能达到100万吨左右,岩棉的产量每年还在递增中。如此大的产量,在岩棉制品制作过程中会产生大量的岩棉下脚料,每年产生的废料达上万吨。这些废料难以降解,污染环境,通常选择的深埋处理不仅浪费人力、运力,还将面对很大的环境压力。岩棉废料的再利用可以减少垃圾填埋的人力费用、运费,还能减少环境污染。减少岩棉废料处理的费用
According to statistics, since 2011, rock wool has been built and under construction in about 40 production lines, production capacity reached 1 million tons, rock wool production is still increasing every year. Such a large amount of production, rock wool products in the production process will produce a lot of rock wool scraps, the annual waste generated tons up to 10,000 tons. These wastes are difficult to degrade and pollute the environment. The commonly-chosen deep-buried treatments not only waste manpower and capacity, but also face great environmental pressure. Recycling of rock wool waste can reduce landfill manpower costs, freight, but also reduce environmental pollution. Reduce the cost of rock wool waste treatment
