Abstract:
The often criminally neglected field of municipal solid waste management, especially in less developed urban regions, will receive in the future their necessary attention. As a result of the increasing process of urbanization, on a global as well as local scale, and the accompanying progressive aggregation of capital, specically human capital, production increases in areas such as consumption of goods are going to result in a dramatic rise in the amount of solid waste generation. Consequently emerging influences on the design of urban living space require more adequate and sustainable approaches for the treatment of municipal solid waste. Whether a particular waste treatment technology should be applied in a final waste disposal strategy, or not, will largely depend on the specific costs of the considered method. This thesis aims to demonstrate a methodology to calculate the price to treat one tonne of waste, paid to a treatment plant operator, that results in a value at which investment in such a plant becomes viable. That designed approach has been used to develop a base model, which includes revenues due to the sale of electrical energy as well as income from the gate fee and afterwards in an expended model, also includes revenues from carbon credit sales.<br />Applying this model to a case study which compares 20 future projects starting one per year over the time period 2011-2030 and takes into account the local conditions of Brazil, results in projections of treatment plant operation-sustaining gate fees. The comparison of these projections with the actual landfill fees paid in the metropolitan area of Rio de Janeiro sheds light on the conditions under which the considered waste-to-energy technology is economically feasible.
