Plastic recycling, yes. Plastic is nearly impossible to recycle because it degrades so much in use (and it's usually attached to other things, contaminated by food, etc.) The vast majority of iron and steel has a very high recycled material percentage. This is a problem for applications where low radioactivity is a requirement, as almost all iron and steel around the world is now contaminated with fallout from decades of atomic testing. Copper, heavily recycled because of its high value. Aluminum also has high recycling because of the immense energy needed to smelt it out of its ore. There are at least two companies providing near 95% recovery of materials from lithium ion batteries. With prices low, there wasn't much economic incentive. Now there's massive economic incentive.
