在制造纸张和纸板过程中会产生大量“飞灰”和污泥。尽管有一些能被用作混凝土中的骨料,但大多数造纸废物最终被倒入垃圾填埋场内。然而这种情况可能即将改变,因为芬兰科学家已经发现其可以被当作塑料制品的原料。作为欧盟Reffibre项目的一部分,芬兰国家技术研究中心(VTT)的研究人员已进行了实验室测试,表明灰末颗粒和污泥可
In the manufacture of paper and cardboard will produce a large number of “fly ash” and sludge. Although some can be used as aggregate in concrete, most of the paper-making waste is eventually poured into the landfill. However, this situation is likely to change soon as Finnish scientists have found that it can be used as a raw material for plastic products. As part of the EU’s Reffibre project, researchers at the Finnish National Technology Research Center (VTT) have conducted laboratory tests showing that ash particles and sludge may
