Sludge to Value

Our work proposes the use of sewage sludge and its ashes to create domestic phosphorus-rich organo-mineral fertilisers. The effectiveness of the use of which has been confirmed by field tests. The grain yield of one corn plant in the experiment increased by 19-43%, the weight of 1000 grains by 14-37%, and the weight of the cob by 60-82% compared to the control. For deworming and disinfection of sludge, reagent-free methods have been proposed that allow for avoiding the accumulation of waste. The isolation of individual elements of high purity from sludge ashes using waste-free technology has also been carried out.
