Abstract

The University of Arkansas Fayetteville (UAF) is actively pursuing ways to increase sustainability on campus. Through the establishment of the Sustainability Council and campus centers, multiple projects are attempting to reduce the carbon footprint at UAF. One particular study is designed to eliminate food waste on campus through composting. The purpose of this study was to evaluate and project the economic savings of implementing a food waste composting system using Earth Tubs. Earth Tubs are an in-vessel electrical composting system capable of diverting up to 150 pounds of organic material daily with minimal odor. Results suggest that composting food waste from one dining hall only over the 15-year life of the project will likely result in an overall increase in food waste disposal costs. However composting waste from all three resident dining halls will likely reduce food waste costs for UAF over the life of the project.
