Inspired by the structure of DNA and proteins, scientists at Rutgers University have developed plastics that break down under normal conditions without heat or harsh chemicals.[1][2] The key is the precise arrangement of the chemical components in the molecule, which creates weak points similar to the fold of paper, allowing decay thousands of times faster than normal.[1][2] These plastics remain strong and useful until decomposition is activated.[1][2] Decomposition can be programmed to last days, months, or years by adjusting the spatial arrangement of neighboring groups.[1][2] Degradation can be built in from the start or triggered by ultraviolet light or metal ions.[1][2][4] This approach makes it possible to tailor the lifetime of plastics to a purpose, such as packaging food for one day or car parts for years.[1][2] Preliminary tests have shown that the decomposition fluid is not toxic, but further safety verification is required.[2]
