16. City Abattoir operations in Uganda require large volumes of hot water to maintain high levels of hygiene which translates into high costs of electricity.

17. 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.

23. In this project an innovative strategy and incentive to achieve sustainable waste treatment and environmental clean-up is proposed involving

24. anaerobic bio-conversion of agro-process wastes to produce biogas and nutrient-rich slurry,

25. aerobic oxidation of anaerobic digestate to reduce organic and nutrient loading and generate nutrient-rich sludge;

26. use of effluent from anaerobic digester and aerobic SBRs to cultivate vegetables, flowers and animal fodder in hydroponic systems and

28. Expected results of the intervention Better treatment of agro-process wastewaters (slaughterhouse, tannery and Banana wine processing wastewaters) Recovery of useable by-products such as biogas, bio-fertilizers, and water Agricultural products (crops /vegetables, flowers, animal feed/pasture grass) Reduction of GHG from agroprocessing Incentive for treatment

29. Project Goal Contribute to climate change mitigation, environmental sustainability, and agricultural development in Eastern Africa through integrated waste management innovation systems

31. 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
