Emerald Energy Waste Facility 

Toronto, Canada

Emerald Energy from Waste

Location: Toronto, Canada

Time of Operation: Over 30 years- Completed in 1992, it has been in continuous operation. 

Specifications & Performance:

  • 400-500 TPD

  • 151,000 tons of MSW, industrial waste, tires, and other specialty waste per year from the Toronto metro area.

  • Operated 24 hours per day, seven days per week

  • Approximately 5 to 6 days of waste is stored within the building, which includes negative air pressure to keep dust and odors within the building.

  • Approximately 7,500 tons of metal per year are recovered. White goods and propane tanks are separated from the waste before gasification. There is no front-end Material Recovery installed at this location. Most of metro Toronto participates in a Tri-Stream Recycling Program where most of the recyclable material is directed to a separate clean MRF, the largest in Canada.

  • At the end of the gasification process in the primary chamber, a small amount (±7%) of vitrified and inert ash drops into a specially designed water-filled ash removal system below the primary chamber, which cools the ash and delivers it to a storage area pending final disposition. The ash is a safe, nonhazardous material suitable for use as landfill cover or as an aggregate in embankments or asphalt products.
