Edmonton’s organics processing program uses the organic portion of the waste collected in combination with biosolids (treated sewage sludge) to create compost, a rich soil supplement. This sustainable process, along with established recycling programs, enables Edmonton to divert over 50% of its residential waste from landfill.
The key operations for processing organic waste currently take place at the Edmonton Composting Facility. This process will be complemented in the near future by the addition of an Anaerobic Digestion Facility.
The Edmonton Composting Facility
Located at the Edmonton Waste Management Centre (EWMC), the Edmonton Composting Facility is the largest of its kind in North America by volume and size. Constructed in 2000, this facility:
- creates compost from 160,000 tonnes of organic waste and biosolids per year
- produces quality compost for use in agriculture and horticulture
- reduces greenhouse gas emissions
- uses bio-filters to reduce odours
Proposed Anaerobic Digestion Facility (ADF)
This facility will expand the City’s organics waste processing capacity and contribute to the goal of diverting 90% of waste from landfill. Located at the Edmonton Waste Management Centre, it will complement the existing organics processing done at the Edmonton Composting Facility.
The ADF will enable the City to:
- process up to 48,000 tonnes of organic waste per year and divert it from landfill
- create renewable energy in the form of electricity and heat
- produce high quality compost for use in agriculture and horticulture
- reduce greenhouse gas emissions
- remove odours created during the process by using bio-filters
This facility is a partnership between the City of Edmonton and the University of Alberta. It will allow both partners to increase their waste diversion rates and continue reducing greenhouse emissions from their activities. The Climate Change and Emissions Management Corporation (CCEMC), with its mandate to provide funding for initiatives that reduce GHG emissions or improve Alberta’s ability to adapt to climate change, has also provided funding.
The ADF is scheduled to be in operation by the end of 2017.

When you put your residential organic waste in the garbage, it gets collected and taken to the Edmonton Waste Management Centre where the organic portion is separated from the rest of the garbage and turned into compost.
