I'm getting to the point where I think plastic recycling was always a scam to make people use more plastics without any guilt. That said, putting plastics into landfill not such a bad thing; we've taken oil from the ground, made it into plastics, then putting it back in the ground. Better than burning it. There is a lot of space for landfill, and not very much oil. The problem is when it doesn't end up in landfill, but ends up in the sea. Which by virtue of there being more and more plastics (since they're guilt-free now) there is more and more of.
