Power generation by coal-fired power plants produces millions of tons of coal fly ash (CFA) as a by-product. Currently, worldwide profitable usage of fly ash is varied widely in different countries from a minimum of 3% to a maximum of 57%, with a global average of about 15-20% of the total ash. The primary uses of CFA in Canada are in cement manufacturing, hydraulic mine backfill (cement replacement), liquid waste stabilization, flowable fill (use for backfill, excavation, sub base, road base), and as mineral fillers.

燃煤发电厂的发电会产生数百万吨的副产品飞灰(CFA)。目前，全球范围内对飞灰的有利可图的使用在不同的国家差别很大，从最低的3%到最高的57%，全球平均约占总灰分的15%-20%。CFA在加拿大的主要用途是水泥制造、水力矿山回填(水泥替代)、液体废物稳定、流动填充(用于回填、挖掘、底基层、道路基层)以及用作矿物填料。
