Mr. Mathieu-Poulin, I don't know if you're the correct person to ask this. It might be for the folks beside you. It's around energy consumption to recycle the plastic, versus the energy that is available in the plastic. I know that, with the waste management in northern Alberta, the plastic becomes a major feedstock for their energy sources, for the waste management more generally. They're using some of that energy to sterilize the composting that they're doing, for example, so that when you get your compost back from the waste management centre, you're not filling your garden full of weeds or something like that.
Can you talk a little bit about the usage of the energy that's available there, and then what it takes to reuse or recycle? Is that a net positive or a net negative?
