Polylactide from PolySciTech Used in Research on Biodegradable Adhesives For Environmental Applications

Blog Post created by John Garner on Jul 9, 2019

Pollution due to nondegradable plastics and commodity products has created an environmental crisis. Recently, researchers at Purdue University used PLA (AP138) from PolySciTech ( as part of research in developing biodegradable adhesives. This research holds promise to solve environmental problems related to plastics pollution. Read more: Siebert, Heather, and Jonathan J. Wilker.

“Abstract: Adhesive are critical for holding together the products that we use every day. Most industrial glues are petroleum-based. These materials are strong bonding, but also permanent, leading to difficulties separating, recycling, and reusing the components. Petroleum-based materials only exist in finite quantities and sustainable alternatives are needed for the future. Results presented here are part of our efforts to develop adhesives that are non-toxic, renewably sourced, and allow substrates to be disassembled for recycling. By systematically studying formulation parameters for a bio-based, mussel mimetic polymer, we now have developed a material that is able to compete with commercial bio-based and petroleum-based adhesives in terms of adhesive strengths on multiple substrates.”
