Abstract
The present invention provides a method for recovery of phosphate, in the form of magnesium ammonium phosphate (MAP), from a process for treating a biomass material which process comprises a digestion step performed in a digestion tank and includes a pre-treatment step employing a thermal hydrolysis, characterized in that a magnesium source is added to the material in the process flow before said flow enters the digestion tank, and phosphate is recovered as MAP as an integral part of a solid or semi-solid digestate product from the digestion tank.
