A living plastic with a pair of cooperative, plastic-busting enzymes degraded the material completely within six days. Credit: Adapted from ACS Applied Polymer Materials 2026, DOI: 10.1021/acsapm.5c04611 Many plastic products are designed to be used only once, yet the material itself lasts for years. But a new strategy is addressing this problem by creating products that self-destruct on command, known as living plastics. These materials incorporate activatable, plastic-degrading microbes alongside the polymers. One team reporting in ACS Applied Polymer Materials used two bacterial strains that worked together and completely broke down the material within just six days, without making microplastics.…
