JHU’s campuses use two recycling systems: dual stream and single stream. Dual stream recycling means that paper and cardboard are separated from plastic, metal, and glass items. Whereas single stream recycling means they can be combined.
- Dual Stream | Homewood, Keswick, School of Medicine, Mt. Washington
- Single Stream | APL, Bloomberg School of Public Health, D.C., Eastern, School of Nursing, Peabody

Prevent many more items from reaching the landfill by taking advantage of the specialty recycling programs and options available at particular locations, or upon special request, on various campuses.
Electronics such as computers, laptops, monitors, printers, and cords can be recycled on all campuses by contacting the appropriate divisional Facilities Office.
Hard-to-recycle items like writing utensils, chip bags, wrappers, personal care products, and more can be recycled at the Homewood Campus through Terracycle. Submit a work order below.
