Bio-Based Coatings and Adhesives

Detailed overview of innovation with sample startups and prominent university research


What it is

Bio-based coatings and adhesives are transforming the way we protect and bond materials, offering a sustainable alternative to traditional petroleum-derived products. They are derived from renewable biomass sources, such as plant oils, starches, lignin, proteins, and other natural polymers. These materials offer a compelling solution to reduce the environmental impact of conventional coatings and adhesives, which often rely on fossil fuels and can release harmful volatile organic compounds (VOCs).

Impact on climate action

Bio-Based Coatings and Adhesives significantly reduce carbon emissions by replacing traditional petroleum-based counterparts. They promote sustainability in industries like construction and packaging by offering renewable, biodegradable solutions. With widespread adoption, these innovations mitigate climate change, advancing towards a greener future with reduced environmental footprint and carbon emissions.

Underlying
Technology

  • Biomass Extraction and Modification: The fundamental technology involves extracting and modifying natural polymers from biomass sources to create materials suitable for coatings and adhesives. This can involve processes like:
    • Extraction and Purification: Isolating specific polymers from biomass, such as starch from corn or lignin from wood, and refining them to achieve desired purity and functionality.
    • Chemical Modification: Altering the chemical structure of natural polymers to enhance their properties, such as improving their adhesion, water resistance, or durability.
    • Blending and Formulation: Combining different bio-based polymers and additives to create formulations with specific performance characteristics tailored for targeted applications.
  • Polymer Chemistry and Material Science: Understanding the chemistry of bio-based polymers and how they interact with other materials is crucial for developing effective coatings and adhesives. Researchers in material science are constantly exploring new ways to enhance the performance and functionality of these materials.
