Ottawa is investing roughly $2.7 million from the Low Carbon Economy Fund to support a project in Petawawa, Ont., that converts food waste into energy.

The Town of Petawawa is also contributing $2.7 million to the project.

“The Town of Petawawa is committed to leading by example on climate change by transitioning the delivery of essential services in a way that reduces greenhouse gas emissions generated from our own biogas produced through wastewater operations,” said Bob Sweet, Mayor.

Sweet explained that the anaerobic digester technology at the existing wastewater treatment plant will be upgraded to a resource-recovery process.

Specifically, the project is described as upgrading the existing anaerobic digester technology to convert the Water Pollution Control Plant (WPCP) from its “traditional treatment-based process to a Resource Recovery process, achieving the goal of being an Energy Net-Zero Plant”.

Biogas generated through the anaerobic digestion process would be used to produce renewable energy onsite through combined heat & power (CHP) engines “and other beneficial use of biogas”.
