Reuse: Social Sustainability 

• Campus Services offers a “free wood” program for community use. This wood is collected from downed and damaged trees that are not used to make mulch or repurposed for TreeCYcle, and is a great way for wood to find a new home while saving people money.
• Information Technology (IT) determines the life cycle of its technology. Desktops and laptops have "two lives" that spans about seven years -- one life is with IT, and the other is with a new owner somewhere on campus. After both of these lives, desktops and laptops go to ISU Surplus to be sold to the public during the weekly in-person sale and online.
• Used grease from ISU Dining facilities is sold to ISU BioBus, a student organization that makes biodiesel from reclaimed vegetable oil and supplies it to CyRide for use in some of their Cybrid transit vehicles that serve Iowa State University and the community of Ames, providing a student-driven entrepreneur opportunity, as well as educational experience for hundreds of Iowa K-12 students who tour the BioBus Laboratory each year.
