It is estimated that globally, 8-10% of total greenhouse gas emissions are a direct result of food waste. Canadians contribute to that global total, creating an estimated 50 million tonnes of food waste every year. Meanwhile, emissions from manure represent 20% of a farm’s carbon footprint. These two challenges may seem unrelated, but there is an emerging agricultural solution that can both reduce food waste and transform the emissions from food and animal waste into energy and fertilizer: anaerobic biodigesters.
Host Crystal Mackay chats with George Dick, owner of Dicklands Biogas, about how biodigesters work and what is needed for biodigesters to become a more feasible option for more farms across Canada.

Canadians create over 50 million tonnes of food waste every year. Canada has pledged to reduce that by half: https://madeinca.ca/food-waste-canada-statistics/
