Every year, over 100 billion nitrile rubber gloves are produced. They are made from synthetic polymers—a material chemically related to plastic and derived from crude oil. The vast majority is used in the health care sector, and most are discarded after single use. This creates a massive amount of material waste globally. However, Simon Kildahl, a postdoc at the Department of Chemistry at Aarhus University, has moved a step closer to a way of recycling these gloves. In a new study published in the journal Chem, he and his colleagues demonstrate how they can transform waste rubber into a CO2 adsorbent in the laboratory. The potential, he explains, is significant.
