Optimizing the collection of used paper from small businesses through GIS techniques: The Leganés case (Madrid, Spain)

This article deals with a methodology for the design of routes for the ‘bin to bin’ (BTB) collection of paper and cardboard waste (PCB) from small businesses, as well as with the new location and calculation of the number of containers needed in the streets for both commercial and non-commercial use due to the large amount of PCB deposited in them. This study was carried out in five shopping areas of the city of Leganés (Community of Madrid, Spain). One of the characteristics of the area is a high density of population and urban traffic.
