Fertilizing residuals (FR)

Fertilizing residuals (FRs) are industrial and municipal wastes such as sewage sludge (biosolids), cement kiln dust and wood ash that have beneficial effects on crops or soil. Manure is generally not considered an FR, because it is an agricultural waste and is governed by special regulations.


Guidelines and documents

Legal and regulatory framework

The legal framework is detailed in the Guidelines for the beneficial use of fertilizing residuals. Other Canadian information is available on the CCME and ACIA websites.
