Kind: research · Impact: medium

## In brief

- Businesses and institutions in about 6% of Montreal's mapped area send roughly 100,000 metric tons of food waste to landfill each year.
- That amount is about half of the total food waste from nonhousehold sources in the city, according to McGill University researchers.
- The study focuses on targeting institutional and commercial food waste in specific high-volume areas.

## Why it matters

The findings show that a small share of urban area accounts for a large part of nonhousehold food waste, suggesting targeted collection could divert more waste from landfill than city-wide measures.
