Presented by IWMI's Johannes Paul (Researcher, Integrated Waste Management) at a stakeholder meeting to inform about the ongoing BMZ funded research project on “Research and capacity-building for soil rehabilitation”, held at IWMI Headquarters, in Colombo, Sri Lanka, on June 21, 2016.

From research to uptake
Brief on the ongoing BMZ funded project
‘Research and capacity building for inter-sectorial private
sector engagement for soil rehabilitation’

2. WLE RRR Flagship
 IWMI Research division
Three activity clusters/subthemes
1. Business opportunities for RRR (e.g. business model development,
feasibility studies, piloting PPP, testing recovered resources, etc.)
2. Safe wastewater use: risk assessment, risk mitigation, economics,
behavior change; with WHO, FAO, UNU, UNEP.
3. Challenges of urbanization for water and land management in urban
and peri-urban areas (e.g. GlobE - UrbanFood+ )
The new BMZ project is mapped under subtheme 1.

3. www.iwmi.org
Water for a food-secure world
Subtheme 1 - What we did so far:
Analyzing and developing RRR business solutions
• 150+ business cases screened
• 60 cases with in-depth analysis
• 22 business models developed
• Feasibility studies in 10 cities

Previous research by IWMI
Research focus in Ghana from 2000 to date (95 % onsite sanitation);
extended to India, Nepal, Bangladesh and Sri Lanka in 2011
– Direct application of urine to soil
– Land application of FS
– Extended storage and drying of FS
– Composting of Feces
– Co-composting of FS and solid waste
– Fortification (blending) of fecal compost with fertilizer
– Agronomic trials (crop and soil response, safety)

Circular Economy
Switch from Linear supply flows to
Agriculture:
decreasing organic matter, soil
deterioration, decreasing yields,
increasing use of chemical fertilizer
Solid waste management:
predominating waste disposal, lack of
waste treatment options, low quality
of recycling products
Sanitation:
Lack of central sewerage systems,
scattered on-site sanitation systems,
uncontrolled septage collection, lack of
treatment facilities, uncontrolled
disposal of FS from tank cleaning
Main challenges
linking inter-sectorial challenges and capacity building

Framework of research project
Goal: Increased business thinking and private sector engagement in
RRR to enhance soil health and resilient ecosystem services by
returning organic carbon and nutrients to agricultural used soils in
low-income countries.
Purpose: To develop curricula for innovative RRR technologies and
investment models that transfer organic waste into organic fertilizer for
different soils, crops and climates in South Asia.
Countries involved: Sri Lanka; additionally to facilitate outreach and
investments India, Nepal, Bangladesh, Laos and Myanmar
Target group: Young entrepreneurs, future leaders, practioners
Beneficiaries: Farmers provided with GAP and natural fertilizers

Main envisioned outcomes
Outcome 1: Technical guidelines for co-
composting and producing safe fecal sludge-
based fertilizer pellets (IWMI, Wayamba)
Outcome 2: Guidelines and Farmers handbook on
safe pellet application (Bochum & Wayamba)
Outcome 3: Country investment briefs, policy
recommendations (ZEF Bonn)
Outcome 4: Curricula for students and RRR
practioners (University Cambridge)
1: Technical research
Main field of activities
2: Verification of soil & crop
responses; fertilizer value
3: Investment climate
analysis
4: Curricula development
Framework of research project
Goal: Increased business thinking and private sector engagement in RRR to enhance
soil health and resilient ecosystem services in peri-urban areas by returning organic
carbon and nutrients to agricultural used soils in low-income countries.

Water for a food-secure world
Outcome 1: Technical research (co-composting, pellets)
• FS treatment, e.g. drying beds
• Verification of suited input materials
• Co-composting (process, quality)
• Pelletization (grinding, binding, enriching)
• clarification fertilizer properties (NPK, pathogens,
organic matter, size, density, pellet strength etc)
• Formulation of production guidelines
FS
SW
FS

13. www.iwmi.org
Water for a food-secure world
• Testing of various fertilizer mixtures (fertilizer quality,
application properties)
• Testing of various crops (short-, medium, longterm)
• Open field and greenhouse trials
• Trials for various weather/climate conditions
• Farmers perception surveys including gender aspects
• Formulation of application guidelines
Outcome 2: Verification of fertilizer value and safe application

14. www.iwmi.org
Water for a food-secure world
• Expert consultations (chamber of commerce,
donor and sector organizations, farmer associations)
• Multi-criteria analysis (regulatory framework, legal,
finance, gender, governance RRR market
• Data synthesis & country briefs
Outcome 3: Investment climate analysis
Outcome 4: Curriculum development
• Development of syllabi and curricula
• Selection of suited cases and business models
• Use of research outcomes from activities 1-3
• Testing of curricula & course institutionalization
