The implementation of solid waste selective collection (SC) systems is quite difficult in low-middle income countries. Lack of awareness, infrastructure, administrative support and knowledge about recycling are the main barriers for its operation, reducing the possibility of successes. This paper introduces the methodological approach for assessing a recyclable waste SC project in a Bolivian public University. The waste fractions generated before (2016) and after (2019) the action were assessed, as well as the opinion and knowledge of the students, providing reliable indicators of the improvements and benefits obtained. Results of the waste characterization analysis reported that, after one month of implementation of the system, about 15 kg of plastic and 37.1 kg of paper and cardboard were collected, about 8 wt% and 42.9 wt% of the recyclable waste produced. At the same time, the questionnaire survey allows demonstrating that the SC behavior of the students improved considerably from 2018 to 2019, (t = -7.654, p < 0.05), as well as the satisfaction about the waste collection service provided (t = -6.6224, p < 0.05) and about the diffusion of information with awareness campaigns (t
