QIEEP is pleased to see proposed new regulatory changes in Ontario that would enable the diversion of low carbon fuels from municipal waste streams.
By recognizing the energy value of these materials – which are currently not recycled – the province will simultaneously reduce pressures on landfills while creating a fuel source for energy-intensive sectors such as the cement industry.
Ongoing research at QIEEP, led by Warren Mabee and Andrew Pollard, is examining the life cycle implications of replacing coal and petroleum coke in cement plants with low carbon fuels including construction and demolition waste. With our partners at Lafarge Cement and the Cement Association of Canada, we are monitoring emissions at the stack associated with using low carbon fuels, and modeling the overall impact of substituting these fuels in the process. Our initial results suggest that the use of low carbon fuels in these processes is safe and represents a significant life cycle savings in terms of overall GHG emissions.
We support the proposed changes by the Ontario government and would be pleased to provide comment on these changes.
