Humans generate heaps of waste every day. Waste rich in energy, nutrients, or water. Most of it gets flushed down the drain, dumped in landfill sites, burned or even abandoned in public spaces or nature. Meanwhile, millions of farmers struggle with depleted soils and lack of water. A new 800-page book profiles multiple ways to harness this waste to help fill the world’s food and energy needs.
In collaboration with the World Agroforestry Center (ICRAF) and the Office of International Programs, College of Agricultural Sciences, Pennsylvania State University, UN-Habitat has launched a project for briquette production in Kalobeyei new refugee settlement and the host community in a commitment to improve access to cooking energy.
Where there’s muck, there’s brass, as the age-old saying goes. At the World Water Week in Stockholm, the International Water Management Institute launched 22 teasers offering an insight into its research into successful business models for turning wastes into money.

From 2011 to 2015, the Resource Recovery and Reuse project – implemented by the International Water Management Institute (IWMI) under the CGIAR Water, Land and Ecosystems research programme – analysed 110 waste-recovery businesses in order to establish guidelines for assessing, implementing and scaling up similar programmes.
By Christopher A. Scott - Wastewater from sewage that is churned out by expanding cities and towns worldwide helps meet food security globally, especially in developing regions. It is one resource (unlike land, labour, or freshwater) that is continuously growing in volume and used to cultivate vegetables, grains, animal feed, and fish at a larger scale than we ever realized.
ROME (Thomson Reuters Foundation) - Untreated wastewater from cities is used to irrigate 50 percent more farmland worldwide than previously thought, leaving some 885 million people exposed to the risk of diseases, including diarrhea and cholera, a study said on Wednesday.ROME (Thomson Reuters Foundation) - Untreated wastewater from cities is used to irrigate 50 percent more farmland worldwide than previously thought, leaving some 885 million people exposed to the risk of diseases, including diarrhea and cholera, a study said on Wednesday.
The use of untreated wastewater from cities to irrigate crops downstream is 50% more widespread than previously thought, according to a new study published this week in the journal Environmental Research Letters.
The use of wastewater to irrigate crops is far more widespread than previously estimated, according to a new study, exposing hundreds of millions of people to health risks and posing a major environmental hazard.
