Sustainability has become a critical focus in epoxy resin production as industries seek to reduce environmental footprints and comply with stricter regulations. Traditional epoxy resins are derived from petrochemical sources, raising concerns about resource depletion and carbon emissions.

To address these issues, researchers and manufacturers are developing bio-based epoxy resins sourced from renewable materials such as vegetable oils, lignin, and cardanol. These alternatives aim to replicate or exceed the performance of conventional resins while significantly reducing carbon footprints.

Recycling and reuse of epoxy composites are also gaining attention. Advances in chemical recycling techniques enable the recovery of fibers and resin components, promoting circular economy practices in composites-heavy industries like aerospace and automotive.

Efforts to reduce hazardous emissions during curing, improve energy efficiency in production, and adopt safer hardeners further enhance the sustainability profile of epoxy resin systems.

As green chemistry principles advance, sustainable epoxy resins are set to become mainstream, balancing performance with environmental responsibility.
