Food Waste

The Guelph Food Waste Research Project, co-led by Dr. Kate Parizeau and Dr. Mike von Massow, investigates food waste across the value chain in Canada. Current research initiatives include studies of food waste at the household scale in Canada, case studies of food waste in different sectors of the food system, and the relationship between food waste and food security.

Graphic with words "building a research agenda for food waste in Ontario"

In 2016, we hosted a multi-stakeholder workshop (Ontario Food Waste Project) to identify food waste research priorities. Learn more here:
