Organic Materials: Maximizing Resource Recovery from Waste Through Biogas and RNG Production

The Canadian Biogas Association, City of London and Union Gas worked together to assess the economic feasibility and environmental benefits of producing biogas by anaerobically digesting the organic fraction of the City of London’s (City) residential waste stream, and subsequently converting the biogas to renewable natural gas (RNG) for use in compressed natural gas (CNG) vehicles.

This work as part of the City's investigation of options for the management of the organic fraction of its residential waste. In this report, two scenarios are considered: collecting and anaerobically digesting source separated organic (SSO) materials or anaerobically digesting organic materials separated from a mixed waste stream at a processing facility (facility-separated organics (FSO)).
