Power to protein

Featured image


What is the goal of the project?

AEB Amsterdam is collaborating with Waternet, KWR Watercycle Research Institute, AgriNutrition, TKI Watertechnologie and Avecom on an advanced procedure to extract proteins from sewage sludge that is then used as animal feed. The quality of the proteins produced in this way is enough for animal and human consumption. It has been calculated that the wet fraction of the sludge digestion at the Waternet purification plant could supply sufficient protein to provide all the residents of the city with 35% of their primary protein requirement. This is the size of the potential. The production of proteins in the form of soya as animal feed, for example, requires intensive farming. This uses a lot of water and farmland. We can prevent that by using this technology instead.

What is the result of the project?

A pilot plant is being tested and constructed for protein production from sludge from the sewage station. Two pilot projects carried out in 2017 that provided insight into and evidence as to whether the proteins production is sufficient to be scaled up.

Who initiated the project and which organizations are involved?

AEB and Waternet
