“Some people call it waste, but we’ve gotten past that where we don’t have to use the ‘W’ word here,” he told Green Energy Futures. “It all has value. It just needs to be utilized in a different form.”
Kotelko’s farm near Vegreville accepts an additional 200 tonnes of organic waste from nearby municipalities, and receives a tipping fee in exchange. Overall, the methane it burns in a 2.5-MW generator produces enough electricity to power 2,500 homes.
