Geração de créditos de carbono através da transesterificação de óleos e gorduras residuais

Abstract

Concern for the environment, linked to economic growth becomes increasingly competitive energy challenge in the world. It is this backdrop that the used frying oil and other oil begin to appear as a strong source of biodiesel in the generation sector of the national production. The production of biofuel from waste this brings many benefits to society, with significant reduction of problems related to disposal. With the implementation of this fuel in the Brazilian energy matrix will result in a positive environmental impact because, in addition to providing a suitable target for waste oil, its use in fleet vehicles will drastically reduce the emission of greenhouse gases such as carbon dioxide, responsible for the effect emissions, and completely eliminate the sulfur, one of the worst culprits of acid rain. In this sense, the objective of this work was to study the feasibility of producing biodiesel by transesterification of used frying oil in the generation of carbon credits. The methodology used to assess the economic viability of the process was the cost of fuel level, prepared using the Cost Index - Benefit (ICB), where it was possible to assess the sensitivity to variations in key parameters (investment and operation cost) . We used the spreadsheet Microsoft Excel ® that formed the basis for calculations of the platform of the process and results in carbon credits. The study showed the feasibility of biodiesel production process, where the great advantage is in the environmental sector, for reducing emissions of particulate matter and sulfur in the atmosphere, brings benefits to public health and the foreign country through the generation of credits carbon.
