Wonder where Green Bin waste goes?

Food WasteEver wonder what happens to food waste put in Toronto's Green Bin?

Started in 2002, Toronto's Green Bin program was one of the first curbside organics collection programs in North America. Soon, more than half of that food waste will be processed right here in Toronto.

The City-owned Dufferin Organics facility processes approximately one-third of Toronto's food waste, and the second organics processor is set to open this summer at the Disco transfer station. The remaining food waste is sent to private operators in other parts of Ontario to process.

Toronto uses an Anaerobic Digester to break down food waste, followed by open air process to finish the compost. This process has advantages:

  • the first stage of processing can happen right in the City on a small site
  • hydropulpers mix food waste with water and remove plastic residue (from bags, diapers etc)
  • anaerobic process (without oxygen) creates minimal odours and the high temperatures kill bacteria
  • anaerobic digesters create methane gas which will be captured to generate green electricity

Want to see green bins in more Toronto places? Write a quick email or make a call as part of the Waste Free Challenge - #7 - Help Grow Green Bins and tell us about it!

TEA's office doesn't have green bins, so we just started worm composting!
