The article points out that there are significant benefits to single stream: - 80% recycle instead of 29% - Fewer trucks - Less fuel - Fewer staff Switching back to multi-stream is misguided. Even with multi-stream recycling you still need to deal with contamination. It's going to be even harder to re-educate people that are used to single stream. Why not focus on better sorting solutions? It is easier to teach a machine learning algorithm to sort based on computer vision than it is to get 325 million people to change their behavior.
