LOCATION OF RECYCLING DEPOTS WITH GIS

A location-allocation model contained within a geographic information systems (GIS) software package was used to design a recycling depot sc heme for a community of 22,000 people. Considered a less expensive alt ernative to curbside recycling, the depot scheme would receive a varie ty of recyclable materials from the public on a voluntary basis. Depot sites were located using a model that maximized the coverage of a dep ot site, with constraints based on projected ''recycler behavior.'' Sh opping centers, municipal parking lots, and roadside sites were candid ate locations for recycling depots in the two modeled cases. A GIS-bas ed approach is shown to be useful for determining the number and locat ion of material recycling depots for use within an integrated municipa l solid waste management system.
