A brief description of programs, policies, infrastructure investments, outreach efforts, and/or other factors that contributed to the diversion rate, including efforts made during the previous three years:

As part of the Carnegie Mellon strategic initiative to enhance the scope and impact of our education and research programs related to the environment, the Green Practices Committee was charged in April 1999 to develop a plan for an expanded environmental practices program on campus.

The Green Practices Committee supports and encourages the Carnegie Mellon community to reduce or reuse all items and recycle as many materials as possible. Items include mixed office paper, cardboard, beverage containers, wood waste & pallets, steel & bi-metals, tires, electronic waste, textiles, scrap metal, plant materials, and food waste.


A brief description of any food donation programs employed by the institution:

Many of dining locations donate their excess food to local food banks and church’s. Vendors donate to community-based non-profit feeding programs, including The Light of Life Rescue Mission and the East End Cooperative Ministry. Data is not available on the actual donation amounts; however vendors are quite effective at controlling the amount of waste therefore, donations are limited and occur primarily after large-scale events.


A brief description of any pre-consumer food waste composting program employed by the institution:

Fourteen dining locations in the University Center and Resnik are currently participating in the pre-consumer composting program. Tazza D’Oro at the R-Bar Cafe’ in the Gates and Hillman Center and LaPrima in Wean Hall are both participating with composting their coffee grinds.


A brief description of any post-consumer food waste composting program employed by the institution:

All vendors, at their discretion, are encouraged to use the compost dumpsters at the Cohon University Center, Gates Hillman, GSIA, Resnik and Morewood Gardens Buildings. While no policies are formally set, some vendors utilize the dumpsters. Several departments collect food waste and hold zero waste events, where all waste generated can be composted. Post consumer food collection was added to the custodial contract and awarded in July 2012 and a post-consumer food composting program was implemented January 2013. As of this submission, we have 50+ locations on campus with post-consumer food composting collection bins.
