BACKGROUND: The declining fibre supply and rising fibre costs in recent years has forced the panel industry in Canada to seek for non-traditional fibre resource including fibre residues as potential source. Sludge is the final solid waste recovered from the wastewater treatment processes in pulp and paper mills, and the largest by-product of the industry. Millions of tons of dry sludge is generated each year in Canada, but most of the sludge has been disposed of through combustion and landfilling, both of which are today restricted by stricker environmental regulations. While several studies have investigated the use of recycled paper fibres mixed with resin for panel manufacturing , no attempts have been made to use the sludge for BINDERLESS medium density fibreboard manufacture.

背景技术背景：近年来，纤维供应下降和纤维成本上升迫使加拿大人造板行业寻求非传统纤维资源，包括纤维残渣作为潜在来源。污泥是纸浆和造纸米尔斯厂废水处理过程中回收的最终固体废物，也是该行业最大的副产品。加拿大每年产生数百万吨干污泥，但大部分污泥已通过燃烧和填埋处理，这两种方式都受到更严格的环境法规的限制。虽然有几项研究调查了使用再生纸纤维与树脂混合制造面板，但没有尝试将污泥用于无粘合剂中密度纤维板制造。
