ReCoVR: Recovery and Circularity of Valuable Resources

Bison code: L.28273

Context/current situation:

Due to the growing world population, resources and raw materials will become increasingly scarce. Therefore, the Dutch government and industry have set the goal to become a circular economy in which all resources are reusable by 2050. To enable this transition, development of novel sustainable technologies that can recover valuable resources from industrial, agricultural and municipal wastewater streams, is essential.

Problem statement:

In various subsidized projects, IWT is working closely together with technology providers and (potential) endusers to develop new technologies and applications for recovering and reusing these scarce raw materials. Although valuable components in aqueous (waste)streams have different origins, the technology to recover and to purify them show many similarities as well as the methods to apply them in new products and processes. Therefore, this project will look for common methods for analysis, separation, upgrading, processing and application.

Project or research goal:

In co-design with of our partners we have identified the following  focus-areas/targets: (I) recovery of N, P and K and S from aqueous waste streams from municipal wastewater treatment systems and from agricultural origin, (II) recovery of S from biogas installations, (III) recovery of alginates from sludge granules from waste water, (IV) the transformation of N to NH3 as carrier/storage for biobased energy, (V) to test the natural fertilizer in so-called the aquaphonics way of performing agriculture, (VI) the use of the alginates as auxiliary material in the construction industry.

Project results:

In this project, you will design, develop and investigate technologies to clean water and to recover valuables resources, to analyze and improve the quality of these recovered materials, to develop applications for these new raw materials,  and to design and build equipment for testing these recovered material under realistic conditions. The results will be key for our partners in further developing processes more efficiently, sustainably and circular, so that The Netherlands will be leading in the worldwide transition to a circular society using aqueous waste streams from the chemical, food, agricultural industries as feedstock.
