Demonstrating sustainability and profitability go hand-in-hand
Walker Emulsions provides both wax and asphalt emulsions to a variety of industries and municipalities across Canada, the United States and Mexico.
Rented and temporarily installed a water softener from a local company to test the viability of producing emulsion using soft water, with the final goal of preventing build-up in process heat exchangers. Fouling in our heat exchangers is an operational reality when using untreated city water, but it can be greatly reduced with some simple process modifications. Fouling reduces heat exchanger efficiency, leads to higher-than-required utility use and decreases lifespan of the equipment.
Hamilton and Burlington
~$70,000 capital investment; <$10,000/year operating and maintenance costs
Natural gas reductions
Additional savings will be achieved through reduction of overtime hours worked, waste generated and energy required for routine heat exchanger cleanings. Fewer required cleanings will also greatly extend the lifespan of the heat exchangers, so maintenance and replacement costs will drop accordingly.
Replaced all 24-hour fluorescent lighting with LED lights.
Installed a coil on a supply air duct at City Hall to reclaim the heat exhausted through the evaporative fluid cooler that is created when the air handling unit is in dehumidification mode.
