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, characterised 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.

Claim (Index 1):
Method for recovery of phosphate from a process for treating biomass material comprising the steps of:\n i) adding a magnesium ion source to a biomass material; ii) subjecting the biomass material to a pre-treatment, comprising at least a step of:\n thermal hydrolysis at a temperature of 140-220\u00b0 C., at saturation pressure; \n iii) transferring the pre-treated biomass material to a digestion tank and subjecting the pre-treated biomass material to an anaerobic digestion at a pH in a range of 7.5 to 8.5 thereby providing a digestate; iv) controlling the pH of the digestion tank by continuously removing biogas, including carbon dioxide and methane gas, and partially or fully separating the carbon dioxide from the biogas, and partially re-introducing the thereby obtained carbon dioxide reduced biogas to the digestion tank; v) optionally reducing the magnesium ammonium phosphate (MAP) concentration in the digestion tank by subjecting a sub quantity of the digestate to a MAP separation treatment and re-introducing any remaining solids or semi-solids into the digestion tank; wherein steps i) and ii) are performed prior to step iii), and wherein the phosphate is recovered as magnesium ammonium phosphate (MAP), or hydrates thereof, as an integral part of the solid or semi-solid digestate product from the digestion tank.
