A Dutch research team has managed to produce protein by reacting the ammonia nitrogen in sewage water with hydrogen and carbon dioxide. This creates a single cell protein that can be used in animal feed and perhaps eventually for human consumption.
Last week, Power to Protein opened its pilot facility in a sewage treatment plant in Enschede, in the East of the Netherlands.
This comes after proving the concept with a 5L reactor, successfully producing a protein “comparable to fishmeal or soymeal”, which are standard animal feed.
