Enbridge Gas Helps Renewable Natural Gas Program ''Mooooooove'' Foward NORTHAMPTON, MA | ACCESSWIRE | September 27, 2022 | Enbridge Gas Inc. saw an opportunity to contribute to a great new renewable natural gas program in Ontario. So we went to work and got it dung. Ontario''s first carbon-negative waste collection truck runs on RNG sourced largely from dairy farm organic waste, and takes just minutes to fully refuel. We''re celebrating today with Ontario Waste Management Association (OWMA) and Bluewater Recycling Association (BRA) the arrival of Ontario''s first carbon-negative waste-collection truck . The truck is fuelled entirely by renewable natural gas (RNG)-sourced largely from cow manure. Here''s how it works: Manure from a southwestern Ontario dairy farm and off-farm organic waste are collected in large tanks called digestors Inside the tanks, bacteria break down the organic material to create biogas. Decomposition occurs in an oxygen-deprived environment, with the resulting biogas comprised of methane (roughly 60%) and carbon dioxide (about 40%) An upgrading process strips out the carbon dioxide, and what''s left is RNG that can be added to the Enbridge Gas distribution system.
