Today is World Water Day and what better way to celebrate than by talking about sewage?
The Stockholm Environment Institute, an international non-profit research and policy organization, released a report on how we can better handle human waste. When it comes to basic sanitation there is plenty of good news including that only 26% of the global population has access to sanitation which is down from 50% in 1990. The report this year looks at how we can use sewage in the circular economy including turning into power to fuel buses.
“We need to reevaluate our view on wastewater and human excreta. Today’s approach to disposal means lost opportunities in the form of nutrients and organic matter which are being flushed away,” says Kim Andersson, Senior Expert at the Stockholm Environment Institute and one of the lead authors of Sanitation, Wastewater Management and Sustainability: From Waste Disposal to Resource Recovery. “Instead, we could use these materials to improve soils or produce clean burning, low carbon biogas. If cleaned properly, wastewater can even be turned into drinking water. Reusing this resource will generate new jobs and business models.”
