Biopolymers as alternative for PVC and PU? I'm working on a project making a product line more sustainable, environmentally friendly and ready for recycling.

Now I'm searching for good and suitable biopolymers for a part of the product that is made from PVC and one for PU (Polyurethane). For PES I already have chosen PLA. Is there someone who can help me select the right biopolymers with similar characteristics of PVC and PU?

Please let me know, thank you!
Ethylene vinyl acetate (also known as EVA) is the copolymer of ethylene and vinyl acetate and is a replacement for PVC.

Biomass > (fermentation) > Bioethanol > Ethene

Ethylene + acetic acid + 1/2 O2 → Vinyl acetate + H2O



Tung oil can be used to create a plastic like water proofing film as a replacement for PU
