Unfortunately, Canadian public coffers are paying subsidies both for the production of plastics and also for these untested and, frankly, not environmentally sustainable processes to try to deal with plastics at the end of life, usually through some manner of burning them or thermally treating them and turning them, as Ms. Wallace mentioned, back into fuel. Fossil fuel subsidies are a much bigger problem than subsidies for plastics, but plastics should not be forgotten when we're talking about the need to transition away from subsidies and from carbon in general.
