3D-printed leaf made with the new bioplastic - Credit: Alain Herzog (EPFL)Scientists at the Swiss Federal Polytechnic of Lausanne (EPFL) have developed a new, PET-like bioplastic that is easily made from the non-edible parts of plants, or "lignocellulosic biomass". The plastic is tough, heat-resistant, and a good barrier to oxygen, making it suitable for food packaging. Due to its structure, the new plastic can also be recycled and degraded back to harmless sugars.
