The problems with recycling plastic are well established. Multi generational heats even under the most beneficial boundary conditions will increase the moduli (brittle), slightly increase tensile, but in general the stress strain curve becomes less predictable with each heat (generation). Under practicable circumstances, waste plastic is full of many variations of additives (colorant, UV inhibitors, glass fiber etc...). All of the real-world circumstances make recycling on a large scale less feasible. There is a SPAC called "purecycle Technologies, PCT" if one is interested in following some of the latest research. Plastics are wonderful to design and mfg in the consumer product world but IMHO, the true cost of this material is not put on the front end and it should be due to the recycling problems
