CAPTURING HEAT FROM INDUSTRY’S ENERGY
The pressure, heat, speed and chemical reactions required to transform resources and materials into products
requires enormous sums of energy. The energy intensity of these industrial facilities dwarfs that of even the tallest
skyscrapers. A by-product, and in most cases also an input, of these industries is heat. The white plumes that
billow out of factory smokestacks are in fact water vapor, whose heat reacts with the cool air to form clouds.
A common reaction might be to think, “Hey, look at all that smoke”, although the more appropriate reaction would
be to think, “Hey, look at all that heat!”
Summing all the recoverable energy from major industrial facilities in Metro Vancouver suggests that approximately
1.3 million GJ of energy could be reused a year. It is important to note however that this assumes industries are
not already recovering heat. Furthermore, it does not provide an indication of where excess heat could be shared
across property lines, as part of a district energy system for example.
Concrete plants, like the one located in Granville Island, are a logical choice for heat recovery. They are located
close to centres and produce large quantities of carbon emissions.
