This pre-feasibility study prepared by the Centro Studi D.E.I Desarrollo Etico Internaciònal - in collaboration with the Italian Chamber of Commerce in Buenos Aires aims to prefigure a course of study - research - design that will be useful to the Municipality of the Metropolitan Norte (AMN) to set about solving the issue management and treatment of waste in their territories. This study starts from the direct observation by Expert DEI, local systems of waste management in the Province of Buenos Aires and, in particular, in the territorial area of the Rio Reconquista, which fall in the area 4 of the 5 Municipalities of AMN (Cuenca baja del Rio Reconquista) . Direct observation , it adds to the experience of BTP in the search for innovative technological solutions and management standards and technologies developed on a European and Italian that can easily adapt to the realities of urban Argentine population densities are high , right from the search Italo-Argentine of has developed an integrated method of MSW management , composed of both systems , high-tech integrated systems of collection, which is registered with the trademark Argentalia® . This pre-feasibility study demonstrates , at the outset, that it is useful to explore the theme through a next step , in a real feasibility study that supports municipalities in dell'AMN important choices to put in place concrete activities and virtuous in which the waste issues can move from the problem situation to that resource.

Management of solid waste is one of the major challenges faced by the municipalities. Solid waste mainly comprises of organic waste. Proper management of organic waste helps minimize solid waste problem. This study was carried out to assess the production of biogas from canteen’s organic waste as a solution for management of organic waste in Solid Waste Management Technical Support Centre, Lalitpur using innovative urban biogas plant with capacity 1,275 liters for 48 days. The physicochemical parameters of canteen’s waste and bio-slurry were analyzed. Similarly, volume of biogas, volume of methane and carbon dioxide in biogas produced were measured and CO2 reduction from biogas plant was identified. The average values of physicochemical parameters of canteen’s waste lied within the optimum range for biogas production. The biogas plant produced 22.03 liters/kg of waste and 120.47 liters/day of biogas. The produced biogas contained 48.89% methane and 39.11% carbon dioxide on average. The biogas plant could reduce 3.20 tones of CO2 equivalent per annum from 262.50 kg of waste fed for 48 days. The values of nitrogen, phosphorus and potassium of bio-slurry indicated it as a better fertilizer. Shapiro-Wilk test showed that the p-value of collected data were greater than 0.05 indicating normal distribution. Linear regression between ambient temperature and biogas production showed that the p-value less than 0.05 indicating significant relationship between them (r2=0.08). The estimated return period of the invested money was 9.5 months in kerosene substitution or 9.7 months in firewood substitution or 9.5 months in LPG substitution. Similarly, the estimated average rate of return was 125.26% in kerosene substitution or 123.72% in firewood substitution or 125.01% in LPG substitution. These results indicated that biogas production using innovative urban biogas plant is better solution for organic waste management. Further extensive and large scale research need to be carried out for the optimization of the biogas plant.
