Abstract

The invention relates to a method and system for phosphate recovering from a waste stream, such as an animal manure waste stream. The method comprises the steps of: providing a tank reactor; 5 providing acidogenic bacteria and/or acetogenic bacteria and the waste stream to the tank reactor, hydrolysing the waste stream, forming a reaction mixture; providing a gas flow to the reaction mixture for removing carbon dioxide from the reaction mixture; 10 providing the reaction mixture to an anaerobic sludge reactor, removing a compound comprising phosphate from the reaction mixture within the anaerobic sludge reactor, and removing gas from the reaction mixture within the anaerobic sludge reactor.
