In this study, the aim was to gain fundamental insights into the mass transfer of hydrogen in bioreactors in order to promote the biosynthesis of single-cell protein. More specifically the study focuses on a bubble column reactor. The initiation of this study was based on the findings from the previous project phases (1 and 2).

In the exhibition Future Food at the NEMO Science Museum, visitors are taken on a future food journey. Plant, animal and functional food scenarios give visitors a glimpse into the future of insects, in-vitro meat, biotech, plant-based alternatives, alternative breeding methods, food as medicine and single cell proteins. The consortium that is working on the…

The Allied Waters Collab H2Bio will continue the work on the power-to-protein concept. The Collab focuses on biosynthesis of organic compounds – such as proteins – by bacteria using green hydrogen as an energy source. Allied Water is a public-private partnership dedicated to implementing innovations in the urban water cycle. The Collab is the main…

The phase 2 Pilot Research is moving towards an end. The pilot studies have stopped and we have started evaluating the data from the tests. Meanwhile we had some material – that was produced during the pilot trial runs – analysed by an external laboratory. During the final campaign we produced the best dry single…

Both the Power-to-Protein Pilot and the Nijhuis Ammonia Recovery (NAR) pilot have been moved to the SWTP Horstermeer of Waternet. After start-up of the pilots in week 44, the focus in the next months will be on the production of larger amounts of microbial proteins. The aim is to produce at least 30 kg so that…

Invited guests from the waste water sector and food sector together with project partners and suppliers will join the official opening of the Power-to-Protein pilot at the SWTP in Enschede. Host is Mr. Jan van Hoek, member of the Executive Committee of Waterboard Vechtstromen and portfolio holder of Water Quality and Innovation. The quests will be informed about…

The research with the special designed and built power-to-protein reactor started last week at the sewage water treatment plant (SWTP)  Enschede of Waterboard Vechtstromen. The reactor will be operated on this location for 4 months and then be shipped to the SWTP Horstermeer of Waternet. The research will focus on the demonstration of the concept and the analysis…

On Friday November 25, Silvio Matassa succesfully defended his doctoral dissertation at Ghent Universtity. The title of his doctoral dissertation was “Exploring protein production by hydrogen-oxidizing microbiomes”. After being awarded a Marie Skłodowska-Curie PhD fellowship, Silvio started his PhD research at Avecom NV in Ghent in january 2014. A close scientific collaboration with the Center of…

The photo shows the Power-to-Protein pilot under construction for phase 2 of the research earlier this month. More precisely it shows the lower part of the Power-to-Protein reactor that forms the heart of the pilot plant. The pilot was built by Maris Machinery in Schijndel (NL) under supervision of Avecom. In the following weeks watertests will be performed to…

During the IWA World Water Congress from 9 – 13 October in Brisbane, KWR researcher Frank Oesterholt gave a presentation on the power-to-protein concept as part of the sessions concerning resource recovery. The presentation focussed on the potential of the concept in the watercycle of the city of Amsterdam but also briefly announced the construction of…
