Résumé:
The use of fossil fuels has resulted in intense environmental impacts that raise the need to
develop renewable energy sources. An excellent alternative is constant research into the
development of energy sources and the production of goods that do not depend on fossil raw
materials. The production of biolubricants from renewable raw materials is an example of
these studies. Just as there is a concern with the scarcity of oil and the development of
sustainable alternatives for energy production, there is currently another problem that affects
everyone: pollution. Although residual cooking oil represents a tiny percentage of waste, its
environmental impact is very large on the ecosystem. One of the methodologies for the
synthesis of biolubricants is the transesterification reaction followed by the epoxidation of
vegetable oil, improving the lubricating characteristics of the oil. This work consisted in the
production of biolubricants from residual soybean oil, from a university restaurant on the
Campus Cuité of the Federal University of Campina Grande, and the comparison with the
biolubricant from commercial soybean oil. The materials involved in the process were
characterized through their physicochemical properties. According to the results, the
production of biodegradable lubricants can significantly help to reduce the environmental
impact of the use of fossil materials for the production of lubricants, as well as the release of
residual oil into the environment.
