Seacliff Energy Ltd.
1) Ontario generates over 9 million tonnes of organic waste annually, much of which ends up in landfills. 2) Seacliff Energy processes 30,000 tonnes of organic waste through anaerobic digestion annually to produce renewable energy. This powers over 1,200 homes and heats greenhouses. 3) Expanding anaerobic digestion in Ontario could process organic waste from over 300 facilities to power 360,000 homes, provide nutrients for 500,000 acres of corn, and heat 1,600 acres of greenhouses. However, barriers like grid access and public opposition need to be addressed.
