The Canadian Council of Ministers of the Environment (CCME) has released a new edition of Guidelines for Compost Quality. The Guidelines serve as the national suggested standard for compost quality regulations for jurisdictions and are focused on environmental health and safety criteria for compost products.
Originally introduced in 1996, the Guidelines detail requirements for compost product testing and identify limits on trace element levels and foreign matter as well as requirements for maturity and pathogen testing. CCME undertook a review of the Guidelines during the past eighteen months, assessing the need for adjustments to the criteria based on new science and technical findings. The review paralleled the Standards Council of Canada’s initiative to review the voluntary national compost standard, Organics Soil Conditioners — Composts, as managed by the Bureau de normalisation du Quebec (BNQ).
