The European Research Council (ERC) has granted Prof. Volker Hessel a Proof of Concept grant. This ‘top up’ grant, worth €150.000, is designed to help ERC-funded frontier research maximize value. With the project, Hessel aims to develop a commercially profitable mini plant producing pharmaceutical raw materials using continuous flow. The current batch production of these raw materials has many disadvantages in terms of quality, efficiency, cost-effectiveness and environmental friendliness. Using the novel micro-reactors, these points can be improved. With the ERC Proof of Concept, the final step can be made to an industrially useful scale.
