In a significant leap toward solving the global plastic pollution crisis, scientists from Murdoch University in Western Australia have developed biodegradable plastics that dissolve naturally in seawater or soil leaving behind no harmful microplastics.
Unlike conventional plastics, which degrade into microplastic pollutants, these eco-friendly alternatives are created using native microbes found in local environments. These microbes produce a natural polymer known as PHB (polyhydroxybutyrate), which safely breaks down without contaminating land, air, or oceans.
Professor Daniel Murphy, leading the research, emphasized the urgency of eliminating plastic waste from ecosystems, especially for the sake of future generations. “We’re looking at plastics that are biodegradable and environmentally benign,” he said.
These next-gen bioplastics are carbon-neutral, non-toxic, and flame-resistant making them ideal for applications like food-safe packaging and compostable linings for cardboard containers.
Harrison O’Sullivan, a PhD researcher on the team, added that the microbes they use are “Australia-made,” naturally storing excess organic molecules and turning them into sustainable plastics.
This innovation could revolutionize the food and medical packaging industries while drastically cutting plastic waste in oceans and landfills.
