Circular Economy

Invalid URL for PDF Viewer

A circular economy means that people are encouraged to reuse materials, energy, waste, water and nutrients to the maximum. To achieve a circular economy, new techniques, as well as new designs, new business models and multidisciplinary thinking are required. Within the circular economy the biological cycle mind-set (biobased economy) plays an important role.

What do we do?

Together with companies, we research and test the newest innovations that contribute to the closing of energy and nutrient cycles. At our test site in Lelystad there is a trial setup for the closing of these cycles: including a fermenter, an algae pond and a bio-ethanol plant linked with a farm. The farm supplies manure and left-over feed to the fermenter, and the digestate returns as a fertiliser for the soil. The heat and CO2 released when the biogas is burned is used to cultivate micro algea and in the ethanol plant. The practical and economical feasibility and the sustainability aspects are considered and researched for all the activities we undertake in this field. 

 Examples

We are working on a concept of purifying wastewater using microalgae and other aquatic biomass. With this new way of purifying wastewater, a large percentage of the nutrients are regained and can be used, something that is impossible with the current techniques. We are also involved in a project concerning the closure of food cycles in cities. 

Partnerships

Put a multidisciplinary team of technically educated researchers and people with practical knowledge together, on a site with various facilities (fermenters, algae ponds and a bio-ethanol plant) and the result is a breeding ground for innovations that could benefit companies.
