I'm not an expert on EPR. I will tell you that. I'm an ecologist. However, from my understanding, you can use extended producer responsibility to incentivize recycling or the use or production of more sustainable items and to deincentivize those that are not sustainable. By using an extended producer responsibility scheme, you can increase recycling.
Again, I think I might ask this question to Mr. Valiante, because I'm an ecologist, not an economist.
