  • Crosslinked polymer networks known as thermoset plastics have many applications, but can’t be reshaped or recycled. A thermoset with reorganizable crosslinks retains its useful properties, but has recyclability built in.

  • 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.

  • Polyolefins are challenging to recycle following a circular model owing to the recalcitrance of their constitutive C–C bonds. Now, a strategy based on intrinsically weakened C–C bonds is proposed to design biologically derived polyolefin-like materials that can be readily deconstructed back to monomers.

  • Biodegradable plastics usually have poorer mechanical or transport properties compared to conventional plastics. Here the authors show a class of biorenewable and chemically recyclable plastics based on copolymers of γ-butyrolactone and its ring-fused derivative, with competitive properties compared to conventional plastics.

  • Among additive manufacturing methods vat photopolymerization (VP) is desired owing to improved efficiency, excellent surface finish, and printing resolution at the micron-scale but the major portion of resins available for VP are based on systems with limited or negligible recyclability. Here, the authors describe an approach that enables the printing of a resin that is amenable to re-printing with retained properties and appearance.

  • Methods for the transformation of plastics into materials with value, known as plastic waste upcycling, are outlined, and their advantages and challenges in terms of a sustainable plastics economy are discussed.

  • To solve the environmental disaster that is generated by legacy plastics accumulation, researchers are looking to design plastics with enhanced end-of-life options, but many circular plastics do not meet industrial requirements. Here, we highlight a metal-free approach to produce chemically recyclable poly(1,3-dioxolane) with ultra-high molecular weight and comparable properties to one of the most produced plastics, polyethylene.

  • UV light-induced polymerization is one of the most efficient methods to produce pressure-sensitive adhesives in lamination processes, as it is simple and easily scalable. Acrylates and/or methacrylates are typically used as the main components, however, O2 inhibitors are needed, which increases the final cost. In this work, we exploit the oxygen insensitivity of thiol-click reactions, evaluate their potential for use in fast and inexpensive UV curable resins, and demonstrate the design of a formulation with competitive adhesive performance compared to conventional acrylic PSAs.
