Polyhydroxyalkanoates (PHA) are biodegradable polymers produced by bacteria through the fermentation of renewable resources, primarily plant-based sugars, ensuring a lower carbon footprint. Thomas Hennebel of Dionymer explains in this interview how PHA can also be obtained from organic waste during processes such as anaerobic digestion. This fact could create interesting synergies with biogas plants. In fact, PHAs have surprising market prospects because they not only have a lower environmental impact compared to traditional polymers but are also completely biodegradable and do not generate microplastics.
