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:

Macalester has substantially decreased its food waste by diverting pre- and post-consumer food waste to a local pig farm. The recycling program diverts paper, glass, aluminum, plastic. E-waste and CFLs are collected from departments and the Macalester community. Finally, the Mac Free Swap was launched in 2009 as an online listing service for the Macalester community. A MacFree Swap dropsite is also available in the Sustainability Office.

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

When large amounts of food are leftover from large events, the prepared foods are donated to Second Harvest Heartland, a local hunger relief organization.

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

In early 2009, a student led project culminated in a partnership between Macalester College, Bon Appetit and Barthold Farms to divert food waste into a pig feed.

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

The food waste to pig farm diversion has grown to include all food waste produced by Bon Appétit, including post-consumer waste and catered food waste.
