• Resumen

  • In this work it's carried out an environmental comparative balance between two methodologies of treatment of residuals: the poured controlled and the incineration. This study has been carried out applying the Life Cycle Analysis (LCA) like tool. The LCA bases an opinion on evaluate the environmental associate loads to a product or activity; in all the stages of that consist: from the obtaining of materials cousins and energy resources, until their elimination. The treatment of a ton of Municipal Solid Waste (MSW) has been elected like functional unit; like compass of the system are considered the Municipal Solid Waste (MSW) since they are deposited in the street until the treatment concludes, that is to say; until the life chemistry of the residual finishes in the spillway or until it is incinerated. Starting from the data picked up in the inventory; meetly classified and characterized, an environmental comparison between the two methods of treatment could have been carried out, considering several stages. The outputs are discussed in function of the environmental impact of each one of the constituent stages of both procedures.
