Reutilização de óleo residual de fritura para a produção de biodiesel e sabão no Distrito Federal

Abstract

The residual oil frying, if not properly designed, it becomes a problem for the various components of sewerage in a municipality, generating impacts on the environment. There are rational and sustainable ways of disposal of this compound through the transesterification process can turn into biodiesel and soap. This is the work of the Environmental Sanitation Company of the Distrito Federal (CEBS) through Biguá Project. The CEBS collect residual oil frying bars, restaurants, condominiums, food and similar industries. The oil collected is intended for Local Productive Arrangements (APLs) organized for the production of biodiesel for use in its own fleet and others, in addition to soap production. In this sense, the present work has as main objective to analyze the results of the residual oil re-frying for the production of biodiesel and soap in the Distrito Federal. With regard to specific objectives, this study sought to assess the benefits of Biguá Project for the operation of sanitation systems and the environment; identify the challenges of Biguá Project; and propose improvements to its efficiency. It was concluded that for sanitation systems, there is a reduction in cases of obstruction of pipes, galleries, sluice gates, and consequent reduction of maintenance. In the natural environment the risk of contamination of water bodies and soil are reduced, which creates less environmental impacts. They identified opportunities for improving program efficiency based on similar projects. The off water and sewer bill, the Biguá seal, the focus of the gathering in denser regions, the partnership with Distrito Federal Urban Cleaning Service, increased disclosure, improved management and environmental education were some solutions found.
