Producing biopolymers from waste water

Industry generates a lot of waste water that has little or no residual value. The Netherlands Technology Foundation (STW) has started a programme, ‘From Waste to Resource’, aimed at adding value to waste water. PTG/e is involved in this project and is responsible for reviewing the materials produced from waste water and their application potential.

One of the projects in this programme, ‘Production of PHAs from Waste’, is aimed at producing the biomaterial PHA (polyhydroxyalkanoates) from waste water with the help of bacteria. A trial run was performed at a pilot plant installed at a chocolate factory and a paper mill, both in the Netherlands.

PTG/e analysed the polymer produced in the pilot plant and examined its potential as a substitute for materials currently being used in these factories – in other words, the possibility to convert a waste stream into a new raw material.
