Cookware handles, electrical plugs, brake pads. Unlike other plastics, these ‘thermosets’ cannot simply be melted down and reshaped, making them difficult to recycle. Chemist Roxanne Kieltyka and her team are now exploring a way to make these materials recyclable, potentially transforming the way we…

Leiden PhD candidate Jo-Anne Verschoor discovered that nearly twenty percent of the bacterial strains she studied could degrade plastic, though they needed some encouragement to do so. ‘Bacteria are just like people,’ says Verschoor. Her research was published in the journal Communications Biology,…
