|YARD WASTE COMPOSTING|
University of Michigan (U-M) Grounds & Waste Management Services collects and transports leaves, brush, and other plant material, to a five acre composting area adjacent to the North Campus Grounds Building. Finished compost is then returned to plant beds throughout campus to enrich the soil.
State of Michigan Act 451 Part 115.
Overview of Procedure
The U-M Grounds & Waste Management Services operates a small scale composting operation for leaves, branches, and other organic lawn and garden wastes. Currently, there is a joint Food Waste Collection And Composting Pilot Program with the City of Ann Arbor and the U-M. Refer to the "Food Waste Collection and Composting Pilot Program" information guide in this section (5-9) for a more detailed discussion of the project.
As a standard operating procedure, mulching lawn mowers are used that do not generate grass clippings for composting or disposal. This is practiced as a labor savings procedure as much as a waste minimization procedure.
Due to the fact that the current site is not adequate to store and compost larger amounts of organic wastes, fall leaves are hauled off-site for land application at Matthaei Botanical Gardens. Also, U-M lacks some necessary composting equipment (tub grinder, windrow turner, and trommel screen), making the procedure more labor intensive.
& Health Precautions/Personal Protective Equipment
The current composting operation lowers costs, because U-M is not paying a fee to a landfill for accepting landscape waste.
