Maybe there is something, but tbh why bother when virgin pellets are better. The best plastic recycling strategy is to not make it in the first place. Or just use other types of packaging - alu cans, glass bottles, paper containers, whatever.
Also additives soak water like crazy. Moisture is a huge problem when making parts - you need to dry some types of plastic pellets in industrial dryers, which eats up a ton of electricity - since they are often running off of compressed air out of a compressor. Most plastic comes in natural colors to which you add additives to change to the color you want. Simply doing that (2% by weight) is a difference between not having to dry at all (since some plastics just don’t absorb water - i.e. polyolefins - which high density variant is what bottles for shower gel, shampoos are made of) and having to dry it for like 6 hours before use.
