I'm not sure if I'm the best person to answer because there are other recyclers out there who will have more data than I would on that particular issue. As a general rule of thumb for packaging recycling in metropolitan areas where you're seeing the sale of material, it's cheaper to recycle that material rather than to create virgin material, so there is an economic case there.
Now, are there diminishing returns? Right now in Ontario, we're recycling about 64% of blue box materials, but if we got to 80% or 90%, I would think that maybe there could be diminishing returns, but I'm not quite sure.
It is a good question, and I take your point.
