Can you believe that it's been eight years since The Coca-Cola Co. introduced the PlantBottle? That breakthrough, first-generation PlantBottle replaced one of the two base components of polyethylene terephthalate (PET) with renewable materials made from sugar cane byproducts. 

Today, biopolymer advancements are progressing at breakneck speed, with a focus to make polymers from non-petroleum, sustainable resources. It's a movement that's accelerated as packaged brands, retailers, and other supply chain stakeholders execute sustainable packaging plans and goals aligned with carbon-footprint reduction and increased environmental health.

We take a snapshot look at the research and commercialization of renewable bioplastics for food packaging found to-date this year. These 10 developments found on Twitter include film windows made from sugar, compostable market acceptance in Europe, "smart" self-repairing polymers from plant-derived pectin, greener clamshell packaging for produce, a home-grown startup that taps corn's potential, protective edible coatings for produce, and more.

This report sets the stage of the global biopolymers market, which is forecast to expand at a 11.45% CAGR 2022-2026 with the APAC region dominating growth.
