No Offer Description Flagship sustainable by design circular composite bioplastics The Wetsus research theme Biopolymers from Water develops and innovates on methods to produce and recover biopolymers, in particular polyhydroxyalkanoates (PHAs). PHAs are renewable resources that serve as a versatile platform for bioplastics within circular economy systems, with wastewater and organic residual streams as feedstocks. PHA-based bioplastics are inherently biobased and biodegradable for the plastics industry, as well as being recyclable and renewable. Through well-controlled microbial processes, PHA-rich biomass can be efficiently generated and the polymers effectively recovered, enabling circular resource use. However, such biobased plastics are still costly to produce. One strategy to enhance recovered PHAs into high-value renewable products for industry is to make biobased composite materials to maximize performance with lower cost to deliver on commercial quality standards - controlled property specifications and materials that are safe and sustainable by design. The entry of 'waste' derived PHAs into circular economic supply chains therefore ...
