Bioplastics from Waste

This will not only reduce the energy costs, but also the equipment cost. Overall, the approach of engineering the environment instead of the bacterium can reduce the cost price of PHA by half. To enable industrial implementation of this highly promising technology the team at Delft University of Technology has initiated research on the development of the overall production chain for PHA production from waste. A multidisciplinary project has been established within the ‘From waste to resource’ research program of the Dutch Technology Foundation STW in cooperation with other Dutch universities and companies. This allows the investigation of up-scaling aspects in a pilot scale process, downstream processing for biopolymer extraction, polymer characterisation and application, as well as overall life-cycle aspects.
