Urban Compost Resources
Welcome to our knowledge hub
We provide resources to help individuals, gardeners, and communities build living soil, reduce waste, and support sustainable urban ecosystems.
Science-Based Composting & Soil Health
At Compost Toronto, our approach goes beyond traditional composting.
We apply principles from soil biology, microbiology, and regenerative agriculture to create biologically active compost that restores soil ecosystems.
Our work is grounded in applied research, including studies in vermicomposting and organic waste transformation, demonstrating how different organic inputs impact:
Soil organic matter
Nutrient availability (Nitrogen, Carbon, Potassium)
Microbial activity
Soil structure and water retention
By combining scientific knowledge with community practice, we help rebuild healthy soils across Toronto.
Why Composting Matters in Toronto
Urban composting is a powerful tool to address some of the most pressing environmental challenges in Toronto:
Organic waste diversion from landfills
Reduction of greenhouse gas emissions
Soil regeneration in urban environments
Support for local food systems and community gardens
Compost is not waste management — it is ecosystem restoration.
