Anaerobic Digestion

The Challenge

The diversion and processing of residential food wastes can be a challenge for municipalities as these materials represent 30% of the municipal waste stream in Canada. When disposed of in a landfill, food wastes can become a significant source of methane - a potent greenhouse gas. One effective solution to divert these materials from landfill disposal and the capture of greenhouse gases is anaerobic digestion.

Recognizing the Value of Organics

Veolia recognizes that each city and business has its own unique challenges in managing its organic wastes and needs to extract maximum value from these materials. We provide unparalleled expertise with a wide range of proven processing technologies that are tailored to our customer’s specific feedstocks and desired outputs such as biogas and digestate.

Biogas can be converted into renewable natural gas for injection into the gas pipeline. Renewable natural gas is being used to power homes, businesses and waste collection vehicles that collect the food wastes - an example of the circular economy in action.

Food wastes can also be co-digested or co-located at wastewater treatment facilities as many of these facilities have anaerobic digesters which are underutilized. Leveraging existing AD infrastructure to process food wastes is an opportunity to efficiently and effectively co-manage municipal organics and biosolids.
