Boiler #1 at Durham York Energy Centre Is Approved for Restart

Covanta Durham York Renewable Energy Limited, the operator of the Durham York Energy Centre (“DYEC”), has received approval to restart Boiler #1.


The DYEC is a new, state-of-the-art $286-million solid waste-to energy incinerator in Southern Ontario near Toronto built and operated by Covanta Durham York Renewable Energy Limited and owned by the Regions of Durham and York.

The facility can process up to 140,000 tons of waste each year, generating some 17.5 megawatts of renewable energy – enough to power between 10,000 and 12,000 homes.

Boiler #1 was brought offline at the end of May following reports of high emission limits for dioxins and furans from that boiler.


The company said that the restart of Boiler #1 would involve using natural gas to bring the combustion chamber temperature up to 1,000 degrees Celsius. Once the boiler reaches 1,000 degrees Celsius, waste gradually is to be introduced until self-sustained combustion can be achieved with only the waste.

Covanta said that it will continue to test, inspect, and monitor several operating parameters of Boiler #1. The company streams emissions monitoring data in real time and posts the data online at the project website (, and on a large electronic board outside of the visitor’s center.
