Nearly any petrochemical derived polymer can also be constructed from plant sugars. Much of this has been known for a while and the real question is how to scale these processes industrially and integrate them with existing supply chains for plastic production. In this case it appears that alcohol is synthesized from plants for production:

... synthesis and characterization of a strong thermoplastic made from 2,3-dihydrofuran (DHF), a monomer made in one step from 1,4-butanediol, a bioalcohol already produced on the plant scale. ...
