Abstract: The sustainability context has received great attention considering the aspects of the current market. In this context, the objective of this paper is to evaluate sustainable alternatives under the perspective of restaurant managers in a federal university in Brazil. Using alternatives focused on sustainability in restaurants, an evaluation under the perspective of different managers to determine the alternatives that stand out the most in the sense of boosting restaurants' sustainability was established. Data referring to the alternatives were obtained from restaurant managers, and the best sustainable alternatives were ranked using the fuzzy TOPSIS method. The results showed that the best alternatives were the correct destination and disposal of burnt cooking oil as well as the reduction of food waste. It was also possible to verify that the restaurants are developing good sustainable practices, and with the results, this paper can offer subsidies about sustainability alternatives for restaurant managers.
