Assessment of alternative phosphorus fertilizers for organic farming: Sewage precipitation products
(2015)Fact Sheet of Improve-PThe application of sewage sludge to agricultural land is currently prohibited in organic farming due to the risk of soil contamination from harmful compounds. Incineration or disposal to landfill of sludge is costly, leads to increased greenhouse gas emissions, and neglects the possibility of nutrient recovery. There are various technologies to recover P by crystallization of precipitation from waste waster and sewage sludge. Depending ...Other Publication -

Random errors may be accounted for in formal uncertainty estimates, but ...Other Publication
