Senior Engineer Circular Economy Coatings and renewable materials

Companies embracing a circular approach will be the resilient strongholds of tomorrow's economy. How can we make your products and processes more circular from a materials point of view? How to use and re-use materials and preserve their value? Which new and sustainable materials are available? How can materials and coatings support concepts such as reuse, repair, remanufacturing, or recycling? What are the priorities and how can we put this into a feasible action plan? Reach out and I would love to discuss how we can make this happen for you.
