Bio-based epoxy resins are eco-friendly alternatives to traditional, petroleum-based epoxy resins. These resins are important for creating environmentally friendly and high-performance composites reinforced with natural fibres.
Thermoset epoxies are extremely hard to recycle due to their strong chemical bonds, which make them durable but not reusable. Most thermoset waste ends up in landfills or is burned, which isn’t environmentally friendly. In contrast, Bio-based epoxies provide a more sustainable alternative, helping to overcome the recycling challenges of traditional thermosets while supporting a circular economy.
A promising way to make thermosets recyclable is by adding special bonds that can be triggered by heat, chemicals, or light. These bonds allow the material to be recycled or repaired. While many are still too expensive or weak for industrial use, some recyclable thermosets (bio-based) are beginning to reach the market.
