About

Using bacteria to produce PHA bioplastics and other high value products from wood residue, in the context of a biorefinery, is an area of research Dr Christophe Collet is focussing on at Scion. Scion’s industrial fermentation platform is unique in New Zealand. It allows us to work with companies to test approaches to modifying and adding value to industrial by-products. We can conduct experiments from 1L to 100L scale, allowing sufficient quantities for downstream processing into a final product, and facilitating the scale-up and technology transfer of industrial biotechnologies.
