6 Promising New Ways to Make Bio-based & Renewable Plastics

As bio-based and renewable plastics become more common the raw materials used for feedstock are also getting more varied.

As bio-based and renewable plastics become more common, and more plentiful, the raw materials used for feedstock are also getting more varied. This slideshow includes a new thermoplastic elastomer (TPE ) made from pre- and post-consumer waste chewing gum, and a new line of black masterbatches that contain 100% recycled post-consumer tires.

While many, many R&D attempts have been made to harness overly plentiful carbon dioxide for chemical feedstocks, few have made it all the way to commercialization on the industrial scale. After many years of intensive effort, chemical giant Covestro has achieved that goal, as we tell you in the following slides. Additives that aid recycling are also becoming more important, and we feature two of those. We also tell you about a first: BASF's new ecovio EA is the first-ever expandable, closed-cell foam material that's biobased and also certified compostable, making it a green replacement for expanded polystyrene (EPS).
