Polylactic acid (PLA) is a biodegradable bioplastic that is already used to produce a variety of everyday items, such as cups, trays, bowls and vegetable wrapping foil. Unfortunately, the current PLA production process is expensive and produces waste. Researchers at the KU Leuven Centre for Surface Chemistry and Catalysis in Belgium have now developed a new production technique that is cheaper and greener and makes PLA a more attractive alternative to petroleum-based plastics.
