Paper is discussing possibilities and limitations of phosphorus recovery from sewage sludge ash, a secondary raw material derived from wastewater. The crucial factors determining the value of this secondary source for possible P-fertilizer production are pointed out. Presented data point the influence of industrial sewage sludge incineration on the bioavailability of sewage sludge ash phosphorus in different soil types. Additionally, the limits given by heavy metal contamination of sewage sludge ash are shown.
