Thousands of tons of ash from forest biomass combustion are being produced each year in Quebec by paper mills and cogeneration power stations. In the coming years, ash production is bound to rise with the increasing use of forest biomass as a fuel in response to concerns over climate change, swelling oil prices, and energy security. Additionally, more than 700 wastewater treatment plants were built in Québec between the 1980s and 1990s following the adoption of a wastewater treatment law in 1978. Municipalities must manage the disposal of approximately one million tons of sewage sludge (municipal biosolids).

魁北克省的造纸米尔斯和热电厂每年都会产生数千吨森林生物质燃烧产生的灰烬。在未来几年，随着人们对气候变化、油价上涨和能源安全的担忧，越来越多地使用森林生物质作为燃料，灰烬的产量肯定会增加。此外，在1978年通过废水处理法后，魁北克在1980年代至1990年代期间建造了700多个废水处理厂。市政当局必须管理大约100万吨污水污泥（城市生物固体）的处置。
