MARKET STUDY ON WASTE HEAT AND REQUIREMENTS FOR COOLING AND REFRIGERATION IN CANADIAN INDUSTRY: OPPORTUNITIES FOR HEAT PUMPING TECHNOLOGIES


Natural Resources Canada recently assessed the industrial opportunities to
recover thermal energy from waste streams. Such thermal sources, both in principle and in
practice, can be upgraded and reused in industrial operations involving process heating,
cooling and refrigeration. The Canadian economy features many industrial sectors that, from
a technical viewpoint, offer opportunities for thermal waste stream recovery. A market study
was performed to quantify the individual thermal waste streams of eighteen (18) Canadian
industrial processes. These streams constitute a theoretical market for energy recovery and
upgrading technologies. The objective of the study was to provide information on the
following:
• Thermal waste streams, characterized by discharged energy content and temperature
range; and
• Cooling and refrigeration needs, characterized by energy content and temperature
range.
The study results constitute an approximate guide to the market potential for recovery
technologies that target thermal waste streams.
