2. Methodology
An optimization process aims at ensuring the effective use of the available resources: material, financial and human. In this par- ticular case, the applied methodology brings together a GIS tool for route optimization, taking into account the available vehicles in the company fleet and a set of ecopoints to be visited, and the def- inition of the best collection frequencies for each glass-waste con- tainer individually, according to its statistical fill-up rate historical data (SIGRSAMARSUL, 2010), keeping unchanged the existing net- work of containers.
