Newfoundland & Labrador Green Fund helps business reuse waste heat

Icewater Seafoods Inc. of Arnold’s Cove will recover waste heat from its current refrigeration system, with the help of approximately $169,000 from the Government of Newfoundland and Labrador’s Green Fund. Through a heat pump system, waste heat generated from refrigeration equipment currently in use will be captured, upgraded to a higher temperature, and then used to heat the facility and supplement fish thawing processes.


“Every time a source of waste can be reused or redirected, it is a positive move for the environment,” said Charlene Johnson, minister of Environment and Conservation. “This innovative project will take a heat byproduct that is now being vented into the atmosphere and reuse it to heat the plant and make processing more efficient. Overall, the initiative will result in a reduction in greenhouse gases of approximately 500 tonnes per year.”


Icewater Seafoods Inc. currently uses an industrial ammonia refrigeration system for ice making, freezing fish fillets, freezing fish offal for use in the pet food industry and maintaining cold storage temperatures. The space and process heating requirements at the facility are met by two oil-fired hot water boilers. The estimated annual fuel reduction for the facility is estimated at approximately 160,000 - 180,000 litres.


“Through this initiative, we will be able to take heat that is already being produced through the refrigeration process at the plant and reuse it where it is needed,” said Bruce Wareham, president of Icewater Seafoods Inc. “This will reduce the demand on our boilers and greatly reduce the fuel required to operate these, thereby making a difference to our environmental footprint.”


According to the provincial government, the project highlights the many ways Newfoundland and Labrador businesses can become more environmentally friendly.
