10. Using participatory urban design to integrate organic solid waste management into urban agriculture: A case study from Cayagan de Oro City in the Philippines

Cattle dung, cooked food waste, and chicken droppings mixed with coffee husks have been used separately and also as mixtures to form anaerobic digestion slurries in a bid to treat to degrade the organic fractions of these wastes and recycle the bio-fertilizer after recovering biogas. Single and mixed substrate slurries evolved significant quantities of methane within 27days together with reduced mass of soil conditioner. The volume of biogas formed in cogeneration mixtures were higher than for single substrate digestion due to the C/N ratio shifting to near 30:1 as a result of mixing. So degradation of organic pollutants was higher in mixed substrate digestion mixtures. Our study yielded average volumes ranging from 315 to 435+ 5.65.mL/L which was in agreement with what is in literature. Digestion of cattle dung, cooked waste foods, and droppings of chicken and mixed substrate slurries using sludge inoculums was very effective in degrading solid waste from homes, thus detoxifying it to bio-fertilizers. Although both single and mixed substrate digestion of waste yielded high enough volumes of biogas; digestion of slurry of mixed organic solid waste substrates is better method of waste management. Digestion of garbage from Kampala should be tested at macro levels at both ambient and mesophilic temperatures. There is need to try out the garbage digestion experiments in the semi-arid towns as well as very cold towns in Uganda.

Industrial Waste Management

The main aim of this project based paper is to provide technological solution for composting process with will help to minimize the composting process and the technology will be easy to adopt. We are facing waste management problems in all areas. Agriculture and Industrial waste management is one of them. There are lot of methodologies available in the market for processing the raw material and making compost. The various methods differ location to location and season to season. The researchers are doing continuous research on the process optimization and to find minimum time to produce compost. Thus, a sound technology is required to improve the quality of manures in the shortest possible time, where farmers can prepare the compost easily and improve its nutritional quality by the addition of cheap amendments as additives in composting. Therefore appropriate composting technology which is economically viable, eco-friendly and socially acceptable is essential. Development of Rapid composting techniques to produce organic fertilizers will help to minimize soil pollution due to chemical fertilizers and will help in Agricultural and Industrial organic solid waste management. We have done few experiments on accelerating composting processes. Use of activated sludge with other additives have helped to improve compost process time and its nutrients. In this paper we have given detail methodology and results obtained from the experiments.
