Quantificação das emissões de biogás em um aterro sanitário localizado na região Noroeste do Estado do Paraná

Abstract

In society, consumerism reigns of disseminated form, being the correct garbage disposal focus of many debates. For both, there are several alternatives, such as the mitigation of waste, recycling, composting and/or biodegradation of organic material and the incineration at high temperatures. However, the practice of these alternatives is still far short of needs, taking a lot of these materials to be deposited as garbage in landfills. Ahead of this fact, this work set out to quantify the biogas generated in a landfill located in the Northwest of the State of Paraná. Thus was made a qualification of waste, noting that there is a selective collection of waste products that reach the landfill; was also carried out an estimate of the volume of biogas, using a lysimeter, in field sampling, which obtained the biogas flow in nine drains the area bounded by the landfill, estimated for the year 2015, and that resulted in 139 m ³. Was also carried estimated by the mathematical method LandGEM, wherein the form of data estimates were obtained for the period where the biogas is still generated in landfills, that is, until the mid 2151 as well as year of maximum production the landfill gas that is 2016. It was concluded that there needs to be a proper management of waste arriving at the landfill, because, that way, there will be greater utilization of waste, enabling-if effective prioritization of waste management. And as a result, the amount of inorganic material would be significantly reduced, which would result in decomposition of waste faster and more efficiently, increasing the production of biogas in the landfill. And if deploying technologies, biogas could be used to generate electricity, which would reduce the emission of CO2, with the possibility of it if measured carbon credits.
