FARMINGTON - The scene on the green today at the University of Maine at Farmington was all about finding things that were thrown away that should have been recycled. The annual event was expanded further this year to include a new program that also generates support for local charities.   At the event sponsored by the UMF Sustainable Campus Coalition, trash generated in residence halls over a 24-hour period are collected to determine how much could have also been recycled.   The coalition has been working with the Sandy River Recycling Association to pull  items for recycling at the transfer station and, at the same time, items  for possible use by Everyone's Resource Depot on campus.  ERD, a non-profit organization, takes recycled goods and offers them for creative reuse, such as art projects and various teaching tools. A nominal fee is charged to support the program.   Another new recycling effort at UMF was added last spring. Items like chip and candy wrappers, solo plastic cups and shampoo bottles are collected and sent to TerraCycle, which turns them into usable products like backpacks and park benches. In turn, TerraCycle pays 1 or 2 cents per item, with all profits coming back to UMF going to the local United Way.   Since the program began, $215 has been raised for United Way of the Tri Valley's charitable agencies and organizations it supports.   Sarah Martin, an adjunct professor in the Department of Community Health and Recreation, came up with the idea of UMF students working with TerraCycle to not only expand the recycling effort on campus, but to also benefit a local charity. UMF student Joe Dignam, a third-year environmental policy and planning major, is an intern working with Martin and United Way's executive director, Lisa Laflin to coordinate the program.   "When I heard about TerraCycle, I thought, wow, we have to do this," Martin said.   The students and faculty sorting trash today found all kinds of recyclable items that were pulled and resorted into categories that will be sent to ERD, the transfer station and there was a good-sized bag that will go to TerraCycle.   "We want to see the percentage of items that could have been recycled," said Luke Kellett, who is UMF's part-time sustainability coordinator and lecturer in the Department of Sociology and Anthropology.   At last year's event they found that 25 percent of the trash could have been recycled. Displaying the trash for all to see at noontime on the campus green helps bring awareness of the recycling effort to the forefront.   "We hope to see progress this year and be below 20 percent," Kellett said.
