Diverting toilet systems - quality of collected urine mixture compared to other organic fertilizers

Urban Farm DB summary

A report on one of several wastewater projects run since 1998 by Storstrøm County and A & B Backlund ApS in Denmark, examining source-separating (diverting) toilet technology and the composition of collected human urine mixture and composted faeces, carried out under an Action Plan administered by the Danish Environmental Protection Agency. User experience in the Danish projects shows the diverting technology is accepted in housing areas, works well in public places, and is highly appreciated in allotment gardens, though further technical improvement is still needed. Comparing the collected urine mixture's nutrient, heavy-metal, organic-compound and microorganism content against organic fertilizers used in Danish agriculture, the analyzed urine mixture was found to be of high quality.
