Genetic engineering adds to waste innovation

03/31/2014 | Forbes

Wastewater and sewage hold the potential for a rich harvest of potable water, scarce minerals, precious metals and biogas for energy, writes Marty Anderson, a faculty member at Babson College who is working with a team of researchers exploring the possibilities. The key to this future is genetic engineering. "Genetically modified bacteria can tune sewage sludge to create customized fertilizer that reduces the amount of irrigation water we need to create the food we eat ... and the 30% we throw away. Modified organisms can even perform the same profitable magic on that food waste," Anderson says.
