Abstract

The application of STELLA, a commercially available, graphically based simulation language for the Macintosh computer, to solid waste facility planning is described. This paper discusses a STELLA model which was developed for the Commonwealth of Puerto Rico Solid Waste Management Authority (SWMA). The model simulates the existing solid waste management system in Puerto Rico and also the proposed system of regional landfills, transfer stations, and waste-to-energy plants. The model incorporates population projections for all 78 municipalities in Puerto Rico from 1990 to 2010, solid waste generation factors for all municipalities, data on remaining life for the existing landfills, and projected startup time for the new landfills and waste to energy plants. The model is being used as a planning tool by SWMA to manage time phased procurement of these new facilities.
