Polyhydroxyalkanoates (PHAs) are natural plastics rapidly compostable and biodegradable in the environment. These can replace the petrochemical products that we now use which are degrading our environment because of their persistance and danger to flora and fauna. These PHAs are not new – products based on these were first developed by the UK company ICI…
The ROBOX Project
Oxygen functionalities are key functional groups in many of today’s chemicals and materials. The efficient introductions of oxygen-functionalities into raw materials are key chemical transformations in bulk and fine chemicals. Innovative bio-catalytic oxidation routes using molecular oxygen (from air) under benign and mild (pH) conditions such as ambient temperature and pressure can greatly improve the sustainability and economics of processes, but are so far mainly been applied in the pharma segments. In this segment, the enzyme-catalyzed step often represents the highest added value and the high price of the end-product (> €1000/kg) justifies less than optimal enzyme production and limitations in its catalytic efficiency. In order to achieve the widening of industrial application of enzymatic bio-oxidation processes to also larger volume but lower price chemical markets, ROBOX will demonstrate the techno-economic viability of bio-transformations of four types of robust oxidative enzymes: P450 monooxygenases (P450s), Baeyer-Villiger MonoOxygenase (BVMOs), Alcohol DeHydrogenase (ADH) and Alcohol OXidase (AOX) for which target reactions have already been validated on lab-scale in pharma, nutrition, fine & specialty chemicals and materials applications.
The introduction of ROBOX bio-oxidation processes is expected to bring substantial reductions in cost (up to -50%), energy use (-60%), chemicals (-16%) and GHG-emissions (-50%).
The ROBOX project has an integrated work-flow structure of 7 work packages.
The intensive networking with our scientific partners enables us to keep at the front line of top-level research and strengthens the knowledge base in the field of industrial biotechnology.
ROBOX PI who has worked in ROBOX on developing enzymes to make the building blocks for polymers gives an interesting talk on the problems of plastics in our environment and makes some suggestions how biobased materials can solve some of the problems. See presentation Youtube
The ROBOX members are presenting at the following upcoming conferences – c-LEcta GmbH will be at the Gordon Research Conference Biocatalysis and at the EMBO workshop “Enzymes, biocatalysis and chemical biology: At the new frontiers to present on the development of ADH and NOX for robust, selective and efficient oxidation reactions suitable for industrial processes.…
