SYDNEY — As the world struggles to contain plastic pollution, eco-friendly alternatives to plastics have garnered attention in recent years. One example: Polyhydroxyalkanoates (PHAs), a naturally occurring bio-based polymer, have been touted as a potential solution. Biotechnology startups have enthusiastically embraced the functional and economic viability of this biodegradable product along with other alternatives, recognizing their potential to replace many household plastics, including the commonly used polyethylene (PE) and polypropylene (PP), both of which are manufactured from fossil fuels and used to make bottles, food containers, packaging, films, textiles and more. Researchers at the ARC Training Centre for Bioplastics and Biocomposites at the University of Queensland in Brisbane, Australia, have developed their own version of PHAs. It’s sourced from sugarcane and “won’t leave a legacy in any natural environment,” Steven Pratt, director of the center, told Mongabay. “It degrades easily in soil, freshwater and saltwater.” Mongabay visited the Brisbane research facility to take a closer look at how PHAs are made and spoke with scientists about their potential applications. While the potential for PHAs is promising, this plastic alternative faces development challenges, including its practicality and the need to rapidly scale up production. Sources Mongabay spoke with emphasized that while dealing with plastic waste effectively is important, it’s vital that the world agree to a global plan to significantly reduce plastic production in the first place.
