Viabilidade econômica do aproveitamento do biogás de pequenos aterros sanitários na reciclagem de plástico

Abstract

The generation of solid waste is part of the social context in which we live, however, the culture of recycling is still undervalued in Brazil. The National Solid Waste Policy, 2010, encourages the enhancement of the recycling process, the organization and the end of the informal waste pickers, and encourage the energy use of biogas generated in landfills. Based on these three points, this study developed a business plan for the deployment of a plastic recycling plant in High Density Polyethylene HDPE, using for this purpose, the energy produced by biogas in South Metropolitan Landfill in Marazion, Ceará. Were developed collection of projects and use of biogas and a HDPE processing plant, as well as raising costs of all the material necessary for the implementation and operation of the plant. We analyzed the economic feasibility of two different environments, by the Cooperative pickers and recycling by the Company. For each environment, were developed three scenarios for the acquisition of the plastic material (100% purchased, 50% purchased and donated 50%, 100% donated). It was found that only the cooperative environment and the third scenario proven to be sustainable for the implementation of a system of this size.
