Ottawa’s Thermal Energy International Inc. has signed a deal worth as much as $11 million for the refurbishment of an undisclosed pulp and paper mill in the nation’s capital. Thermal Energy, an Ottawa maker of emissions control technologies, announced the deal on Wednesday saying the project included the design, development and implementation of energy efficiency technologies and greenhouse gas reduction at the mill. Once completed the project is expected to provide the customer with annual natural gas savings of more than 35 per cent, while reducing its annual greenhouse gas emissions by more than 20 per cent, or approximately 43,000 metric tonnes.
