Waste as a Resource
Tuesday 19 August
Workshop 1 - Full Day Workshop
Convenor : Stockholm International Water Institute (SIWI)
Co-Convenors : Global Water Partnership (GWP) and International Water Management Institute (IWMI)
Highly populated cities generate enormous quantities of waste. After separation of hazardous components most of the waste can be re-circulated, nutrients and other components can be withdrawn from it, and heat and bio-gas can be produced. The treated wastewater itself can be used for irrigation, groundwater recharge, other beneficial purposes and to maintain ecological flows. Sewage sludge, which contains organic matter, nutrients, microelements and valuable humic substances necessary for agriculture, also has great potential for reuse if properly treated. The collection and treatment of waste should not only be viewed as a necessary expense to promote health and safety. Instead, it presents great opportunity as a largely untapped and valuable source of organic matter.
This workshop will focus on ways to develop systems that can best utilise resources hidden in treated wastewater, sludge and solid waste. How can this be accomplished without posing risks to health, safety and the environment? With increasing pressure on conventional energy sources, it will also be important to provide relevant examples on the best ways and practices to use these resources for energy production.
