Recovering nutrients from urine – A golden opportunity for sustainable fertiliser production
PLANTS, PEOPLE, PLANET, EarlyView.Agricultural industrialisation has led to levels of nutrients in the environment that are well above safe operating limits, yet fertiliser use is necessary to feed a growing population. The recovery of nutrients from human urine in large, developed cities may offset some of the ecological and economic impacts associated with fertiliser production, as ...
