The University of Minnesota Twin Cities campus is one of the largest campuses in the United States. It encompasses 1,000 acres, and includes over 250 buildings.
The Recycling Program is housed within Facilities Management, the department that manages all University physical facilities. In 1992, the Recycling Program was integrated with the well established resources of the Waste Management Unit in order to increae efficiency and the recovery of materials diverted from the solid waste stream. In addition to the ReUse Program, these units come together to create Waste Abatement Services.
Routes
With a few exceptions, it is the responsibility of the custodial staff to transport materials from various containers throughout the buildings to a central storage location, usually located on or adjacent to the loading dock for the building.
Storage areas are serviced by recycling personnel as part of two recycling routes. The large route services between 30 and 35 locations daily, while the small route services 12-15 locations per day. Almost all buildings on campus are picked up at least one day a week, although many have multiple pickups weekly or daily. All materials are brought to the Como Recycling Facility, located between the two campuses.
Recycling in University Residence Halls
Housing and Residential Life has purchased their own recycling containers for use in all campus residence halls. The containers are centrally located within each building. Housing and Residential Life handles the promotion of the program within each residence hall. Residence halls are serviced by the University Recycling Program as part of the normal recycling routes.
Processing--Major materials (paper, glass, cans and bottles)
 At the recycling facility, hampers of paper are emptied by a mechanical dumper onto a 25-foot conveyor belt where the paper is sorted to remove contaminants. Contaminants, if paper, are sorted by category into gaylord boxes. At the end of the conveyor, the paper falls into the hopper of a horizontal baler. Bales are stored in the building and eventually loaded onto 53 foot trailers and shipped directly to paper mills.
 Comingled cans and bottles are sorted on separate equipment. Bags of cans and bottles are emptied into a hopper which loads the materials onto a conveyor. One person sorts glass and plastic bottles from the conveyor. Glass bottles are placed into self-dumping hoppers by color which are eventually emptied into roll-off boxes for shipping. Plastic bottles are sorted, sent up the vertical conveyor, and baled in a horizontal baler. At the conveyor, aluminum foil and plastic are also removed for recycling, along with trash and other unwanted items. At the end of the conveyor, the remaining cans travel through a magnetic separator which removes tin cans, storing them separately. The remaining materials (aluminum cans), are directed through a flattener and sent by a blower into a 30-cubic-yard roll-off box, then shipped for recycling. Tin cans that were removed by the magnetic separator, as well as a separate stream of bagged tin cans and foil received from University Food Services, are sorted in a similar manner, flattened, and directed to roll-offs for collection and shipping.
Cardboard
Cardboard is the only material that does not come to the Como Recycling Facility for processing. It is collected directly from campus buildings with a rear load packer truck, and is delivered directly to local recycling facilities near campus.
Processing--other materials (other grades of paper, metal)
In addition to large-scale collection of office and newspaper grades, the Como Recycling Facility collects other papers with the newspaper plus program; including magazines, hard and soft cover books, and phonebooks. Paper grades that are not baled are stored in gaylord boxes and shipped to various mills. |
