Many Canadian motorists might not know it, but they are likely to soon be pumping some fraction of their gasoline or diesel made from animal fat, restaurant grease or agricultural and forest residue into their vehicles at every fill-up. And that level is set to grow ever higher, thanks to incoming Clean Fuel Standard (CFS) to replace volumetric-based requirements with a carbon intensity-based approach.

While adding biofuels like ethanol generated from corn or wheat crops at relatively small concentrations to the fuel supply has long been part of the equation, new methods are under development to expand the feedstock mix and blend it into the fuel stream earlier, at the refinery.

And in some respects Canadian refineries are leading the way in blending of new feedstocks to create the next-generation renewable biofuels needed for the future. Parkland’s Burnaby Refinery, for example, has been piloting canola oil and animal tallow since 2017 and is actively investigating the blending of other next-generation feedstocks like wood and agricultural waste and municipal sewage sludge.
