Bioplastics and Biopolymers

Detailed overview of innovation with sample startups and prominent university research


What it is

Bioplastics and biopolymers represent a revolutionary shift in material science, offering sustainable alternatives to traditional petroleum-based plastics. Bioplastics are plastics derived from renewable biomass sources, such as corn starch, sugarcane, vegetable oils, or even algae. Biopolymers encompass a broader category, encompassing all polymers produced from biological sources, including not just plastics, but also resins, fibers, and elastomers. These materials offer a compelling solution to the growing environmental crisis caused by plastic pollution and dependence on fossil fuels.

Impact on climate action

Bioplastics and biopolymers, under the main theme of Bio-Based Materials, significantly impact climate action by reducing reliance on fossil fuels, lowering carbon emissions in production, and offering biodegradable alternatives to traditional plastics. Their adoption promotes sustainability, mitigates environmental harm, and fosters a circular economy for a greener future.

Underlying
Technology

  • Biomass Conversion: The key technology involves converting various forms of biomass into usable polymers. This can be achieved through different processes, including:
    • Fermentation: Microorganisms are used to break down biomass into simpler compounds, which can then be polymerized.
    • Chemical Modification: Existing biopolymers, like cellulose, are chemically modified to create new materials with desirable properties.
    • Direct Extraction: Certain biopolymers, like polyhydroxyalkanoates (PHAs), are naturally produced by some microorganisms and can be extracted directly.
  • Polymer Science & Engineering: Bioplastics and biopolymers utilize principles of polymer science and engineering to optimize their properties for specific applications. This involves controlling molecular weight, crystallinity, and other factors to achieve desired strength, flexibility, biodegradability, and processing characteristics.
