Integrated Solid Waste Program Wins CAFR Award

The Colorado Association for Recycling, or CAFR, has awarded Facilities Management’s Integrated Solid Waste Program the Outstanding Government Recycling/Waste Diversion Program Award. Recycling at Colorado State began a few decades ago, but has made tremendous progress since receiving a grant in 1990. The waste collection and disposal processes were overhauled to allow for efficient collection and recycling bins can now be found nearly everywhere on campus. Currently, CSU landfills about 44.9% of solid waste, with the existing recycling program diverting the other 55.1%. Those figures do not include the (literal) tons of items collected through the Leave-It Behind and Surplus Property programs that are recycled, donated to local charities, or sold for reuse to the local community.


RecycleMania is a friendly competition among college and university recycling programs in the United States that provides the campus community with a fun, proactive activity in waste reduction. Over a 10-week period (2-week trial and 8-week official), campuses compete in different contests to see which institution can collect the largest amount of recyclables per capita, the largest amount of total recyclables, the least amount of trash per capita, or have the highest recycling rate. The primary goal of this event is to increase student, faculty and staff awareness of campus recycling and waste minimization. All participating schools are required to report measurements on a weekly basis. RecycleMania provides many ways to gain recognition, including RecycleMania trophies, awards, and participant certificates. RecycleMania helps all participating colleges and universities make achievements in recycling and waste reduction! For additional information, please visit the national RecycleMania site Colorado State University has participated in RecycleMania annually since 2004 and has consistently placed in the top 5% of schools in the nation-wide Grand Champion category.
