Anaergia
Inc., based in Canada, has announced that it signed a design-build agreement
with the town of Petawawa, Ontario. Under the terms of the agreement, Anaergia
will upgrade the existing anaerobic digesters located at Petawawa’s
Water Pollution Control Plant (WPCP).
Anaergia
will install its Omnivore system, upgrading the WPCP digesters to process
biosolids from the wastewater treatment operations along with organics from the
municipal solid waste stream. The digesters will then produce biogas that will
be used to fuel a combined heat and power engine, reducing the plant’s
dependence on fossil energy supplied by utilities, and reducing its operating
costs.
“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. 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,” says Andrew
Benedek, chair and CEO of Anaergia. “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.”
The project
is designed to achieve net-zero carbon emissions for the WPCP and to convert
the existing facility into a resource recovery center for organic waste. In
this way, it will contribute to creating a circular economy in the region while
contributing to Ontario’s efforts to divert waste from landfills.
In addition
to providing the digester technology and ancillary equipment, process
integration and overall project execution, the contract also calls for Anaergia
to provide technical services to the WPCP for a period of 10 years.
