Anaergia Inc. signed 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's OmnivoreTM 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.

The digesters will then produce biogas that will be used to fuel a combined heat and power engine, reducing 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. 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.
