Resource Recovery & Reuse (RRR) Research Program
16th SuSanA Meeting at the 2012 World Water Week
Waste management in low-income countries cannot keep up the pace with urbanization
Land degradation and nutrient depletion characterize large areas of agricultural production
“Wasted” resources ≠ Need for water, nutrients and energy
Wastewater – Water (irrigation, aquaculture)
Agro-industrial waste - Energy
MSW, Faecal sludge - Nutrients (ag. production)
Waste reuse has great development potential from the ff. perspectives:
Initiatives aimed at RRR have been characterized in most low-income countries by:
Fundamental gaps in:
Resulting in more failures than successes.
Solutions within Reach: Innovative existing, emerging, and potential RRR business models
Agric. use of untreated and treated fecal sludge
Cost recovery options through wastewater irrigation & aquaculture
Energy from fecal sludge ( financial leverage for nutrient recovery)
Agro-industrial waste to energy ( model transfer to human waste)
Water for a food-secure world
1. Research phase: case analysis, model development and feasibility testing of business models for large scale application (4 – 6 cities).2. Implementation phase: Investment in business start-ups, scaling-up of existing businesses (SDC pledged already funds).
Identification of 150+ business cases across Asia, Africa and Latin America
Thank you and please tell us if you know interesting reuse business cases!
