Trinseo’s Jean-Luc Dubois Discusses PMMA Depolymerization in Chemical Engineering Magazine

Dubois explains that chemical recycling is complementary to traditional recycling methods and expands the types of materials that can be used as recycled feedstocks through the case study of polymethyl methacrylate (PMMA) depolymerization.

An excerpt from the article :

"Research shows, within [chemical recycling], that depolymerization is the most sustainable option because, by returning the material to monomer form, there is, in theory, no limitation to the recyclability of the solution in a closed-loop system.¹ In this context, closed-loop refers to when waste plastic can be used in exactly the same application, whereas in an open-loop system, the waste is recycled into another, less demanding application. Additionally, this enables the recycling of contaminated or difficult waste."
