Abstract
Concern in relation to creating environmental protection policies is increasing, particularly with regard to the reuse of waste for power generation. In this context, biodiesel production from waste cooking oils could play an important role. Biodiesel is a biofuel that can be produced from saturated fatty raw material discarded by restaurants, such as oils and fats used for cooking processes. This paper describes a biodiesel production plant installed at Pinheira Beach in the State of Santa Catarina, southern Brazil and aims to discuss the environmental, social and economic impacts by analyzing the biodiesel production by life cycle assessment (LCA), relationship with the emission of greenhouse gases. The plant is run by an association and is aimed at promoting the recycling of waste cooking oil from restaurants and residences in the area and, at the same time, enables the continuity of artisanal fisheries in the region. The transesterification production process was used to convert waste cooking oils into biodiesel using basic catalysis in the presence of methanol. A batch system with the capacity to produce 200 L of biodiesel per day was adopted. The data obtained for the biodiesel produced at the plant were 879.2 kg mâ3 density, 495.74 mg kgâ1 water content, 94.38% ester content, and 1.5 mg.kgâ1 sodium plus potassium. Related to the Life Cycle Assessment the results demonstrate that the category that most contributes to the emissions generated in biodiesel production process is the collection stage with 92.10% contribution, presenting a significant difference to the productions stage which contributed 7.9%. The plant provides environmental, social and economic gains for the community, for instance, increased income for the associates and fishermen, environmental education in schools, and cooking oil recycling opportunities.
