1. The Challenge
Municipal waste is the number one polluter of surface water in Canada. Greater Victoria and Greater Vancouver remain the two largest sources of raw or minimally treated sewage on the BC coast, dumping billions of litres of raw or undertreated sewage into BC coastal waters each year.
Over time, that waste represents millions of dollars of potential for heat and other renewable energy getting dumped – literally – down the drain.
In addition, there are over 4.5 million tonnes (or 1 tonnes per person) of solid waste produced in B.C. per year and many municipalities are running out of land for the disposal. Sending untreated waste to landfills not only produces toxic leachates but sends many compounds like methane, a strong greenhouse gas, freely into the biosphere. By integrating our organic solid and liquid waste streams, what we currently throw away could become a source of energy for all British Columbians.
