Recovering valuable phosphorus from wastewater for use as fertiliser

August 19th, 2012 by Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB

Sewage sludge, wastewater and liquid manure are valuable sources of fertiliser for food production. Fraunhofer researchers have now developed a benign process that enables the recovered salts to be converted directly into organic food for crop plants. Phosphorus is a vital element not only for plants but also for all living organisms. In recent times […]

Threats to the Ocean of Life and what must be done to restore it

May 28th, 2012 by Allen Lane

In Ocean of Life we get a panoramic tour beneath the seas: Why do currents circulate the way do? Where exactly do they go? How has the chemistry of the oceans changed? How polluted are we making them? Above all, Professor Roberts reveals the richness of their life, and how it has altered over the […]

Using bacteria to recover dwindling phosphate resource from sewage

March 30th, 2012 by Society for General Microbiology

Bacteria could be exploited to recapture dwindling phosphate reserves from wastewater according to research presented at the Society for General Microbiology’s Spring Conference in Dublin in late March 2012. Phosphorus – in the form of phosphate – is essential for all living things as a component of DNA and RNA and its role in cellular […]

Wasteful use of phosphorus in agriculture is a key concern in UNEP Year Book 2011
