Towards a sustainable production of bioplastics from residual flows, PHA2USE and the Interreg NWE project WoW! recently took another important step. In the first extraction campaign on a pilot scale, we succeeded in producing more than 18 kg of PHBV from sewage sludge. The produced PHBV, a fully biodegradable bioplastic, is now being tested by companies on various commercial applications.
Keeping in mind the climate objectives formulated by the EU, the question is no longer whether we should re-use residual flows, but how we can achieve this in an efficient and high-quality manner. This also applies to wastewater. Wastewater is already an important source of energy and raw materials such as biogas, cellulose and phosphate. For a number of years, various (European) projects have also been looking at the possibilities for producing bioplastics from wastewater.
