OP-T2-23: Landscape Waste Composting
Director of University Sustainability
Does the institution compost or mulch waste from grounds keeping, including grass trimmings?:
A brief description of the composting or mulching program:
Purdue University has adopted a composting and mulch system as part of the University’s Sustainable Landscape Plan. Purdue utilizes mulching mowers to return grass clippings and leaves back to turfgrass areas. Likewise, brush and leaves are collected for composting. The Purdue Grounds Department manages two State-certified composting locations on campus. Additionally, Purdue has agreements with the cities of Lafayette and West Lafayette to receive leaves and brush from the municipalities. Compost processed by Purdue Grounds is used to amend topsoil, used on capital and in-house construction projects, for landscape maintenance, and in the greenhouses.
Purdue leases a portion of the campus designated composting land to a private company (Soilmaker) which partners with Purdue to recycle brush and organic materials as soil amendments. Compost processed by Soilmaker is refined into several blends of amendments for commercial customers.
