Stony Brook University, the largest public university in New York by area, has continued its 23-year tradition of turning tree debris into mulch for campus beautification. The 1,454-acre campus includes thousands of trees that produce tons of downed limbs from storms and scheduled pruning.
For over two decades, Stony Brook has been committed to sustainability through a recycling initiative that converts woody debris into high-quality mulch. This effort involves collecting debris from overgrown greenery and fallen trees and collaborating with vendors to transform it into mulch for the university's landscape.
“Facilities and Services is proud of our campus’ recycling efforts, particularly our annual initiative to transform woody debris into mulch for our campus garden beds and landscapes,” said Bill Herrmann, vice president of Facilities and Services. “This is a perfect example of how Stony Brook continues to reduce waste to landfills while fostering a more sustainable environment.”
Each year, a vendor grinds the accumulated debris into fine mulch, which is then distributed across the university’s garden beds. The mulch helps retain soil moisture, suppress weeds, and enhance the appearance of plantings on campus.
“This mulch is essential for the grounds departments,” explained Facilities and Services Manager Michael Youdelman. “It not only beautifies our campus but also helps in water retention and soil enrichment.”
Youdelman noted that approximately 3,000 tons of mulch are processed annually. The material is allowed to sit for six to eight months before use to ensure stability and effectiveness. “The mulch needs time to sit and stabilize,” he said. “Once ready, it reduces in size by about 40% and becomes safe to apply without harming vegetation.”
The recycling program plays a crucial role in maintaining the health and beauty of the Stony Brook campus. Youdelman emphasized the educational aspect of this initiative: “I see this initiative as an opportunity to create an end product. Instead of going out and buying mulch, we put it back on the campus land from the very trees that grow here. Turning waste into valuable resources is something we’ve done for years, and it’s something I’m proud of.”— Beth Squire
