Many of the new materials, including Ingeo and Mirel from Natureworks and Telles respectively, can be composted in either a home or industrial facility which could divert the materials from landfills.
However, industrial composting facilities that accept plastic are few and far between and infrastructure to collect and sort waste is still in its infancy.
Although, theoretically reusing the bio-based resins is possible, in practice this too suffers from a lack of infrastructure to separate it out from the rest of the waste stream.
