Design Principles

"Design for Chemical Recyclability: Select polymers and product architectures that can be effectively deconstructed into valuable monomers or feedstocks through chemical processes."

As plastic waste continues to accumulate, innovative recycling methods are crucial for sustainable resource management. Chemical recycling presents an opportunity to create a circular economy for plastics, reducing environmental pollution and conserving finite resources.

06

What This Means for Your Design

Chemical recycling breaks down plastic waste into its basic chemical building blocks, which can then be used to make new plastics or fuels, unlike traditional recycling which often degrades the plastic.
