  1. Resource Recovery & Reuse – Why is reuse important? Miriam Otoo – IWMI Resource Recovery & Reuse (RRR) Research Program 16th SuSanA Meeting at the 2012 World Water Week

  2. Waste management in low-income countries cannot keep up the pace with urbanization

  3. Land degradation and nutrient depletion characterize large areas of agricultural production

  4. Great mismatch - “Wasted” resources ≠ Need for water, nutrients and energy Wastewater – Water (irrigation, aquaculture) Agro-industrial waste - Energy MSW, Faecal sludge - Nutrients (ag. production)

  5. Waste reuse has great development potential from the ff. perspectives: • Food security • Waste management • Environmental benefits/ ecosystem services • Social benefits

  6. Something is amiss as… Initiatives aimed at RRR have been characterized in most low-income countries by: • High dependence on subsidies; • Limited up-scaling potential. Fundamental gaps in: • Economic aspects and institutional linkages; • Business planning and management strategies; Resulting in more failures than successes.

  7. Solutions within Reach: Innovative existing, emerging, and potential RRR business models Examples: 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) ….

  8. Objective of the Resource Recovery & Reuse (RRR) Program: • To increase the scale and viability of productive reuse of water, nutrients, organic matter and energy from domestic and agro-industrial waste streams through the analysis, development and promotion of related business models. Water for a food-secure world

  9. RRR program – new research area within the CGIAR Water, Land & Ecosystems Research Program (CRP5)

  10. One of our core research projects – RRR: Research to Implementation • Composed of two innovative and interlinked concepts: • Analysis, development and promotion of economically viable RRR business models – led by IWMI; • Development of related Sanitation Safety Plans (SSPs) – led by WHO

  11. Research Approach 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).

  12. Identification of 150+ business cases across Asia, Africa and Latin America

  13. Current status of activities • 50+ cases so far have been selected for detailed analysis, more under screening; • 18 business models so far identified: • Wastewater reuse = 5 • Nutrient recovery-based = 8 • Energy recovery-based = 5 • Development of 25+ business models tailored to different waste sources, processes and products, for different entitiesis target.

  14. Target audience • Private sector • Business schools • Public sector • Donors • IWMI has co-funding from IFAD and BMGF • Hire several post-docs • Analyze more cases in detail •  The project is important part of

  15. Key Beneficiaries • Municipalities • Farmers • Low-income communities

  16. Thank you and please tell us if you know interesting reuse business cases! Contact: Resource Recovery & Reuse team@ International Water Management Institute (IWMI) http://www.iwmi.cgiar.org/Topics/RRR http://wle.cgiar.org m.otoo@cgiar.org
