What will be your role?

Bioenergy and biochemicals/-materials are considered to play a main role in the transition to a sustainable society. Biomass provides structural and molecular functionality, which is very effective in replacing fossil-based chemicals and materials. Moreover, biomass provides a sustainable carbon source. 

We are looking for an experienced scientist/chemical engineer that will work on researching and developing new thermochemical technologies for conversion of biomass and plastic residues. You will be closely involved in our Biorizon research activities aimed at further developing our Pyrena/PyPo technology to produce valuable liquid fractions from biobased feedstock. Based on a good understanding of the future business opportunities of the technology and of the associated potential clients, you will take the lead in fully understanding the Pyrena/Pypo technology. You will propose and implement the required adaptations to make the technology work together with the project team as well as a team of engineers. Recently, we have built a new experimental set-up for this at the Green Chemistry Campus in Bergen op Zoom. You will work in a multidisciplinary project team that includes technical experts as well as business development experts. Moving forward, you will also be involved in the research and development of other novel thermochemical technologies in the BCT group.  You will be located in Petten, but expectation is that you will spend part of your time at the Green Chemistry Campus in Bergen op Zoom where the main Pyrena/PyPo setup is located.

The research department Biobased and Circular technologies (BCT) researches and develops breakthrough technologies to convert biomass, and biobased and plastic residues into sustainable chemicals, materials and energy products. These often proprietary technologies are in general based on thermochemical conversion, such as MILENA/OLGA gasification and Torwash upgrading. BCT consists of approximately 50 people with various educational backgrounds, such as in chemistry, chemical technology, and mechanical engineering at both technical and academic level. Technology and application research and development is conducted in multidisciplinary teams and, when successful, technologies are validated at pilot-scale as a first step in bringing them to market together with our commercial partners. In this way we make a concrete impact on the energy and chemicals/materials transition, and we contribute to making the Netherlands and the rest of the world more sustainable. In order to be able to conduct this research at the highest level, BCT has extensive labs in Petten (main location) as well as a smaller location on the Green Chemistry Campus in Bergen op Zoom

How do you want to contribute to tomorrow's world? How big can your impact be? Come and work at TNO and envision it.
