Please use the University's approved and recommended asset disposal method, Ben's Attic, for the recycling/disposal of your department's used equipment: https://upenn.unl.edu
All University faculty and staff members are able to view the listings by logging onto the website with their PennKey. Currently, only TAC holders can post listings and bid on or purchase the items. TAC holders can also designate people to post or bid on their behalf, by sending an email to email@example.com, copying the senior business administrator, and requesting to add the designee to the list of approved persons. Questions or comments about the site can also be sent to that email address.
