  • Catalytic deconstruction offers a route from waste plastics to monomers and oligomers that can be repolymerized into new plastics. Zeolite catalysts engineered with extra-large pores, hierarchical pore networks or nanoscale dimensions can help to address the diffusion limitations of conventional microscale zeolites in plastic upcycling — an important step towards a more circular plastic economy.

  • Chemical recycling of mixed polyester waste presents a monumental challenge for achieving a circular plastics economy due to material incompatibility and contamination. Now, a catalytic methanolysis process demonstrates a scalable, efficient and selective method for recycling mixed polyester waste.

  • Waste management has transformed over the past half a century, from key dumping and landfilling laws in the 1970s to today’s complex policies targeting plastic waste reduction and recycling. Still, global disparities are glaring, and stronger policies, infrastructure and technology are necessary to achieve a truly circular plastics economy.
