In 1986, the Metropolitan Council awarded the University of Minnesota Recycling Program a $10,000 Incentive Grant to develop a collection system for the composting of yard waste. Yard waste is seasonally generated with peak outputs during the spring and fall. During this time, personnel collect the excess accumulation of leaves and grass clippings that cannot be managed with mulching mowers. The waste is loaded into an empty packer truck or roll-off box and delivered to a compost lot on the St. Paul Campus where it is managed by Building Services. The resulting compost is used for landscaping needs across campus. Brush and tree limbs are chipped, and the chips are used as ground cover around trees and shrubs. Tree limbs larger than six to eight inches in diameter are hauled to a county chipping site. Approximately 200 tons of yard waste is recycled each year. Large animal waste bedding generated from the cattle, pig, and horse barns are collected separately and composted. The compost is used to prepare soil mixes for the campus grounds and greenhouses, spread on the agricultural fields, made available to the public, or sold to local, private greenhouses. |
