Published in 2018 at "Waste and Biomass Valorization"

DOI: 10.1007/s12649-018-0215-z

Abstract: Phosphorous is a scarce resource and there is a need to develop methods for recovery of this irreplaceable nutrient from secondary resources, e.g. from sewage sludge ash (SSA). Today SSA is most often disposed of… read more here.
