Urban Sanitation

Urban sanitation-

• Urban population is increasing significantly in recent years and cities are getting hot spots for the sanitation.

• Increasing population also produce a significant amount of waste in cities which contains a significant amount P and N.

•  Transportation of these waste back to the agricultural farm is expensive so we need a new technique which can produce mineral fertilizer from this waste i.e. PNExt

• Urine contains a significant amount of nitrogen but it is difficult to collect in the urban area.

• We need to look for a new way to collect urine separately mainly in urban area.

• if we can collect urine in a large scale it is economical to produce mineral fertilizer from urine using PNExt technique

Can we collect urine in conventional toilet in urban area/ large cities???
