Abstract

This research proposes a relocation plan for source-separation stations (ecological points) on a 95,000 m² school campus, considering operational constraints along with social, environmental, and service factors. A mixed multi-criteria location method is adapted, integrating objective factors (collection distances/costs) and subjective factors (coverage, pedestrian traffic type, soil condition, and visibility). The campus is segmented into five functional zones; for each zone, candidate locations are evaluated, and a location preference measure is calculated to select the final set. The result is a network of 23 stations distributed to enhance accessibility, reduce collection routes, and support environmental education and source-separation strategies. Implications for educational institutions in similar contexts are discussed, and future validation lines based on measurements of recyclables capture and contamination are proposed.
