  • Well done !!! It was very vital project for Eastern Africa !!! I am glad to hear such project that integrates wastewater and climate change mitigation!!! Thank you for all of you who start this project (Dr. Mekibib David Dawit !!!). This is the real project and it is good also if it will expand more and more !!!
    With kind regards

  5. 5. Budget and Distribution<br />Project Budget and duration:USD 1,199,258 over three years (2011-2013)<br />WSP & Constructed Wetland USD 404,084 <br />Makerere University USD449,724 <br />University of Addis Ababa USD345,450<br />Banana Investment Contributing USD 150,000<br />
  6. 6. The Project – City Abattoir<br />The abattoir has a slaughter produces an average of 400 m3 per day polluted wastewater effluent (COD > 10,000 mg/L) significantly contributing to nutrient enrichment and oxygen depletion of Lake Victoria. <br />City Abattoir operations in Uganda require large volumes of hot water to maintain high levels of hygiene which translates into high costs of electricity. <br />The abattoir also uses large quantities of charcoal to prepare meals for over 2000 persons visiting or working at the abattoir on a daily basis. <br />Recovery of biogas from slaughterhouse wastewater for local consumption will reduce charcoal usage by about 80%<br />
  7. 7. Modjo Tanneries<br />The Modjo tannery for example generates 4 500 m3/day of wastewater with a COD content of 10 000 mg/L which is discharged to Modjo river feeding into Lake Koka (Ethiopia). <br />Downstream communities use this lake for irrigation and other domestic activities and this poses a health risk to these communities. <br />
  8. 8. Banana Investments Ltd<br />In Tanzania, Banana Investments Ltd processes 25 metric tons of peeled ripe bananas per week to produce wine in a process that produces about 400 m3 of high-strength wastewater (BOD, 3000 mg/L) per day. <br />The enterprise unsustainably uses 3600 cubic meters of wood fuel per year costing the company USD 50,000 per annum <br />

  11. 11. The Project - Innovation<br />The current wastewater treatment processes do not integrate pollution reduction, energy and nutrient recovery. <br />In this project an innovative strategy and incentive to achieve sustainable waste treatment and environmental clean-up is proposed involving <br />anaerobic bio-conversion of agro-process wastes to produce biogas and nutrient-rich slurry, <br />aerobic oxidation of anaerobic digestate to reduce organic and nutrient loading and generate nutrient-rich sludge;<br />use of effluent from anaerobic digester and aerobic SBRs to cultivate vegetables, flowers and animal fodder in hydroponic systems and <br />finally polishing of this effluent in constructed wetlands and using the treated water for farming .<br />

Innovation Pathway<br />Sludge fertilizer (UG)<br />Biogas, slurry fertilizer (UG, TZ)<br />ProcessWater<br />Agro-processing Plant<br />Anaerobic digester (UG, ET, TZ)<br />Treatment in Aerobic SBR(UG, ET)<br />Treated water for irrigation (TZ) <br />Treatment in CW (UG, ET, TZ)<br />Disinfection (UG, ET)<br />Hydroponic system (UG)<br />Crops, Flowers (UG)<br />Treated water back for washing (UG, ET)<br />
  13. 13. Expected results of the intervention<br />Better treatment of agro-process wastewaters (slaughterhouse, tannery and Banana wine processing wastewaters)<br />Recovery of useable by-products such as biogas, bio-fertilizers, and water <br />Agricultural products (crops /vegetables, flowers, animal feed/pasture grass) <br />Reduction of GHG from agroprocessing<br />Incentive for treatment<br />
  14. 14. Project Goal <br />Contribute to climate change mitigation, environmental sustainability, and agricultural development in Eastern Africa through integrated waste management innovation systems<br />
  15. 15. Project Objectives<br />Objective # 1: Strengthen capacity to sustainably manage agro-process wastewater in Eastern Africa by 2013<br />Objective # 2: Develop and optimize innovative wastewater treatment processes integrating biogas production and water/nutrient reuse for enhanced industrial and agricultural productivity in Eastern Africa by 2013<br />Objective # 3: Evaluate and disseminate the economic, environmental and social benefits of the integrated wastewater treatment bioprocesses by end of 2013<br />
  16. 16. Project Outputs and Performance Indicator<br />An environmental innovation consortium II strengthened and supported to generate and use technologies for sustainable management of agro-process wastewater in E. Africa<br />Number of human resource with skills and knowledge to operate and maintain the integrated process in partner countries by the end of 2013 (Baseline is needed)<br />At least three innovative integrated technologies developed and operational by 2013<br />
  17. 17. Project Outputs and Performance Indicator cont.. <br />Integrated and optimized bioprocesses comprising wastewater treatment, biogas production and water/nutrient reuse installed and operational in Eastern Africa<br />At least three integrated technologies installed lead to 90% decrease in pollution by 2013 at partner agro-processing locations in Eastern Africa<br />Cost-benefit analysis reports of the integrated bioprocesses for the three project subcomponents produced <br />Number of agro-processing industries, NWSCs, municipalities and regulatory agencies (NEMAs) and S&T Councils/Commissions in Eastern Africa using the report increases by 2014 <br />Number of financial institutions willing to fund waste management investments<br />
