I'd imagine a lot of these could be replaced with certain varieties of PLA that are sourced from bio-feedstocks and also relatively biologically degradable. Some PLA isn't very biodegradable, and certainly many would contain problematic plasticizers and other harmful chemicals. Additionally, PLA doesn't have the mechanical stiffness and toughness needed for many applications - but I think if the market for that expanded greatly, research investment would create new varieties of biodegradable PLA which could function as a drop-in replacement for a larger portion of other plastics.
