An Economic Analysis of a University Educational Cafeteria Composting Program-Bobcat Blend

摘要

At Texas State University, a cafeteria-composting pilot program was established in which students source-separated their organic waste at one of the food courts while the program educated students on the value of organic waste and compost. Waste sorting bins were set up in a dining hall to direct students to sort trash into recyclables, compostables, and trash. Waste audit results demonstrated the value of the operation to the university in terms of savings in waste hauling expenditures, as well as showed the percent contamination, and percent waste diverted to the university's recycling and composting program. There was a significant difference between pre and post-test waste audits. The pilot site composting program resulted in a net loss of $3741.35 to the university during the first year, but was expected to produce a positive net return of $2585.11 in subsequent years. The pilot test showed the program was most successful when ongoing education at the dining hall occurred. Additionally, the student-run composting program resulted in hands-on training for students in producing a valuable horticultural commodity in an emerging waste management field. Results also indicated opportunities for further diversion such as the incorporation of compostable cups and utensils, as well as through expanding the operation to include more collection locations. With more collection sites and, therefore, more efficiency, the expanded composting program has the potential to become a self-supporting operation.
