The inadequate disposal of residual cooking oil used in homes, as well as in commercial establishments such as restaurants and snack bars; has become an aggravating environmental pollution due to its 'disability' after use. In Brazil, according to the Brazilian Association of Vegetable Oils Industries - ABIOVE, the production of cooking oil in 2016 was 7,885 thousand tons; the projection according to the same, for the year 2017 is 8,200 thousand tons of soybean oil. This work suggests the alternative of the production and laboratory analysis of ecological soap as a way to recycle residual cooking oil collected in the cafeteria of the University of the State of Pará, in campus VIII (Marabá), as well as the dissemination of the work to the community through as a form of sustainability and environmental education. For the development of the work, we collected 10 liters of the material from the frying during a period of 20 days, which served as the basis for obtaining a daily average of cooking oil generated residual. There was production for analysis purposes and after interpretation of the results in an experimental manner according to the appropriate specifications of the chemical characteristics of the soap and based on the opinion of those involved with the application of the questionnaire, two soap production workshops were held: the first , held in June with students from the campus itself; and the second, held in October, with the participation of employees from the general services sector of the campus itself and SEAGRI - Municipal Secretary of Agriculture of Marabá-PA. More than the preservation of the environment and its natural resources, the recycling of the oil for the production of bar soap or liquid generates economic gains, being obtained at a lower cost than the one to obtain the commercial product. It was found, with the realization of the workshops, that the 3 participants are more concerned with preserving the environment and requesting more actions that aim to improve the quality of life ...
