BURLINGTON, ONT. — Anaergia Inc. signed a design-build agreement with the Town of Petawawa, Ont. to upgrade the existing anaerobic digesters located at Petawawa’s Water Pollution Control Plant (WPCP).
Anaergia’s Omnivore system will be used to upgrade the WPCP digesters to process biosolids from the wastewater treatment operations along with organics from the municipal solid waste stream, states a release.
The digesters will then produce biogas that will be used to fuel a combined heat and power engine, reducing the WPCP’s dependence on fossil energy supplied by utilities and reducing its operating costs.
The project is designed to achieve net-zero carbon emissions for the WPCP and to convert the existing facility into a resource recovery centre for organic waste.
The contract also calls for Anaergia to provide technical services to the WPCP for a period of 10 years in addition to providing the digester technology and ancillary equipment, process integration and overall project execution.
“This is the first wastewater plant in Canada that will benefit from Anaergia’s unique suite of technologies for upgrading existing wastewater infrastructure into a facility that will produce renewable energy,” said Andrew Benedek, chairman and CEO of Anaergia, in a statement. “The technologies used here have already been proven in the U.S., most recently at a facility belonging to the Victor Valley (California) Wastewater Reclamation Authority. The Petawawa WPCP will serve as an important reference site for Canada. We expect to convert many more facilities in Canada and elsewhere as such conversions make economic and environmental sense. Furthermore, it makes wastewater plants resilient to power interruptions.”
