    • Computers, Laptops, Monitors, Printers - For personal items only - students, staff, and faculty can dispose of these safely at a one-time end-of-the-year event called GreenUp.  For college-owned equipment, contact the OIT helpdesk.
    • Cell phones - Contact Nicole Pedercini in the Controllers Office. She has kindly offered to recycle unwanted phones along with the ones she recycles for her office.  Remember to wipe the memory clean before getting rid of it.  And if it is an iphone, disable the "Find my iphone" function.

  • During the pandemic, the college partnered with TerraCycle to launch a mask recycling program to collect and recycle disposable masks, i.e., the N95s, KN95s, and other varieties we've been relying on for the past weeks.

    We are in the process of phasing out the program but still have collection boxes in the following locations.

    While the program is still up and running, please help us collect and properly recycle masks so that they don't end up in the landfill, on the sidewalk, or in the ocean.


    Don't throw your used masks away anymore, bring them to a collection box near you. Thank you for your support!

    Poster that says "Recycle your disposable masks here!" Surgical masks, KN95, N95, KF94, and similar only. No cloth masks! Poster shows images of acceptable and unacceptable masks
