Waste generation is present in several enterprises with varied dimensions, especially in educational institutions, because they concentrate a high flow of students and employees. Therefore, the purpose of the study was to analyze the gravimetric composition and per capita solid waste generation of the University Restaurant (RU) of the Federal University of Viçosa (UFV) - Forestry Campus (CAF). The study was conducted during the period of one week starting on 02/12/2019 to 06/12/2019 and for the waste characterization the three meals provided by the restaurant were considered: breakfast, lunch and dinner, and in all stages of the production process - preparation, rest-of-ingestion and dirty leftovers -. The per capita production was determined from the generation of rest-of-ingestion. The results indicate that 5,207 meals were served, in which lunch accumulated the highest demand. Regarding the origin of the waste, the preparation and the rest-of-ingestion corresponded to the most significant proportions of waste with 39.43% and 41.63% respectively. It is noteworthy that the amount of organic matter produced was 830.1kg (97.7%) and the recyclable waste and rejects presented 20.4kg (2.3%). When analyzing the per capita production values (176.16 g.waste/meal.day), we can see that lunch and dinner were more than three times what is recommended in the literature. Thus, it is necessary by the RU managers when developing their activities, aiming at reducing the source of this waste.
