Large scale nutrient recovery from domestic wastewater

Domestic wastewater is an important carrier of resources, especially water and nutrients – which are hardly recovered in the current centralised wastewater management systems. Run4Life demonstrates an alternative strategy for improving nutrient recovery, based on a decentralised treatment of segregated black water (toilet wastewater), grey water (other domestic wastewaters) and organic kitchen waste. Different innovative technologies are combined to achieve this goal. At 4 sites in Europe, for the first time nutrients will be recovered from domestic waste streams of several 100 dwellings. In collaboration with fertilizer producers, the resulting products will be characterised and the possibilities for their agricultural application will be determined. End users and other stakeholders are a fundamental part of this evaluation to achieve institutional, legal and social acceptance.

Paradigm shift

About Run4Life

The world food supply is entirely dependent on the use of fertilisers. However, the current fertiliser production practices are not sustainable. Phosphate rock is a non-renewable resource, whereas the nitrogen-based fertilisers production is highly energy-intensive, currently relying on the use
