When you think about wastewater what comes to mind (and nose)? Likely, a long list of bad-smelling, murky colored substances: human waste, sewage, food scraps, oils, soaps, and chemical pollutants. While no one argues that wastewater is a messy cocktail, a huge environmental hazard, and a painful headache for industry and municipalities, it also has unfulfilled potential as a valuable contributor to sustainable agriculture and a global food secure future. Given that half of the world's population will suffer severe water stress by 2030, the time has come to stop looking at wastewater as a liability and start maximizing its potential as a resource.
