Facts about ammonia
In Dutch sewage water treatment plants tens of thousands of tons of ammonia-nitrogen are destructed to nitrogen gas every year at the cost of 9 to 40 MJ/kg NH4-N (Annamox and conventional nitrification/denitrification respectively).
At the same time in fertilizer plants an even bigger amount of nitrogen gas is converted to ammonia in the Haber-Bosch process also at the cost of 45 MJ/kg NH4-N.
Power-to-Protein is about closing this artificial nitrogen cycle by direct N upcycling as microbial protein.
The basis is a highly efficient microbial resynthesis process with a mixed culture of bacteria that use hydrogen as an energy source.
Idea holder and emeritus professor at Ghent University (LabMET), prof. dr. ir. Willy Verstraete states:
“The technology for recovery of reactive nitrogen as microbial protein is available but a change of mindset needs to be achieved to make such recovery acceptable.”
Together with its research partners KWR Watercycle research Institute investigates the technological, economic and environmental feasibility of the Power-to-Protein concept.
News and Updates
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…
This summer Avecom and KWR will start the construction of the pilot plant for the production of SCP on-site. Recently the functional design was completed including the P&ID and subsequently a HAZOP was performed. The first pilot location will be at the WWTP Enschede of Water Board Vechtstromen.
