Food waste has always been a concern for people and governments across the globe, but Toronto Organics has set a precedent through their innovative initiative. They are all poised to convert food waste into renewable natural gas which is also known as RNG.
In collaboration with Enbridge Gas Inc, The City of Toronto will set up the equipment at Dufferin Soild Waste Management Facility. Biogas upgradation will take place at this facility renewable natural gas production.

Various Uses of the Gas Produced
The gas will be used to power the waste collection trucks apart from using it for heating the city buildings and facilities. The city will see a huge reduction in carbon footprint as Toronto moves forward with this visionary innovation. Companies offering bio-cng in India find this idea extremely innovative and far-sighted.The Big Idea
The idea struck when the city of Toronto realized that the Dufferin Solid Waste Management Facility could do more to manage their biogas. The idea of converting organic waste into renewable gas was first discussed in year 2014. Carlyle Khan, the director of infrastructure and resources management, solid waste management services for the City of Toronto said that once they discussed about the idea of converting biogas into renewable natural gas, the obvious next question was what would be the next step. It was decided that designing and installation of the biogas upgrading infrastructure will be done by Enbridge and it would be done next to the Dufferin Organics Processing Facility. An injection station would also be facilitated along with. Enbridge undertook the responsibility of the maintenance and operation of the facility for the next 15 years.Process Explained
The process of converting food waste into renewable natural gas is pretty simple. Separated organics are taken to the Dufferin facility where pre-processing and contaminant removal process takes place. In the next step, anaerobic digestion process takes place as it is fed into the digestors. The process takes place in the absence of oxygen. Biogas consisting of about sixty percent methane is produced.This produced biogas is sent to a biomethanization unit in which it is conditioned and cleaned before it is injected into the distribution grid as renewable natural gas.
If you think that biogas is the only product of the entire process, you couldn’t be more wrong. Digester solids which are also a by-product of the process are processed into compost. About 1,60,000 tonnes of organic material is collected every year in the city of Toronto, out of which 55,000 tonnes of it is successfully managed by Dufferin Organics Processing Facility alone. About 3.2 million cubic metres of renewable natural gas is produced. This amount of gas is capable of fueling 1871 cars.
