Florian Graichen



Dr Florian Graichen is General Manager for Scion’s Bioproducts and Biomanufacturing Areas – which include the Portfolios covering High Value Biorefineries, Distributed and Circular Manufacturing, Bioproducts and Packaging and Integrated Bioenergy. These activities are directed at solving new product and process challenges and opportunities that arise through transition to a Circular Bioeconomy - a new economy focused on sustainable design and renewable resources. This transition is unlocking a generational and transformational opportunity for the country - mitigating climate change and creating prosperity from this transformation. Around the world, bio-based industries are leading the green transition away from fossil-based resources that have been the backbone of our economies for centuries.

In 2022 Florian was appointed as an Honorary Professor by the University of Waikato in the School of Engineering. He is board member of Packaging New Zealand and the Bioresource Processing Alliance. Florian also represents New Zealand on the Australian New Zealand and Pacific Islands Plastics Pact (ANZPAC) Collective Action Group and is a member of several advisory groups to New Zealand ministers and ministries.
