City of Edmonton, Alberta

The City of Edmonton, Alberta in collaboration with the University of Alberta and BIOFerm Energy Systems, will begin constructing in 2016 an anaerobic digester to create energy from its organic waste.

The BIOFerm High-Solids (BIOFerm Dry Fermentation) anaerobic digester to be built will aid Edmonton with its goals of diverting 90 percent of residential waste from going to landfill and to reduce greenhouse emissions. Anaerobic digestion technology in Edmonton will be incorporated into the City’s existing composting operation, ensuring maximum sustainability of the organics by making most of both compost and biogas products from anaerobic digestion.


The facility is sized to initially process 40,000 tonnes per year of high-solids, organic waste supplied by the City of Edmonton and the University of Alberta. However, the chosen design can handle 48,000 tonnes/year of organics. This waste will primarily include:

  • „Municipal solid waste
  • „„Source separated organics from industrial, commercial, and institutional waste sectors
  • „„Yard waste

Energy Production Overview

The 1.426 MWel combined heat and power unit will have:

  • 1.426 MW electrical capacity
  • 1.5 MW thermal capacity

Average annual energy production:

  • 12.5 million kWh electrical production
  • 45,300 MMBTU thermal production„

Estimated energy could:

  • Provide electricity to 1,107 homes
  • Heat 1,031 homes per year

The methane produced and used is equivalent to the avoided release of: 46,000 metric tons CO2 per year, and the energy generated is equivalent to reducing emissions from „„11,786 metric tons CO2 per year from a conventional bituminous coal facility.

Organic End-Products„

Will produce approximately 20,000 tonnes of high-quality compost for sale.
