Ink cartridges are recycled on campus. If you leave several in a box
or something by the mailboxes, the mail room staff will take them when
they make their mail rounds and drop them off at the bookstore who in
turn recycles them. If they are a larger toner-style copier
cartridges and needs to be mailed back to the manufacturer, the
department needs to package it up with return postage on it, leave it
for the mailroom to pick up.
Student Information Center in Devos, Pew Campus, takes larger toner
cartridges and smaller printer cartridges and sends them into a
company for credit which turns into money to purchase K-12 teacher
scholastic books for classroom libraries. They need the cartridges
sent in the plastic wrap, guards and boxes to keep the toner (ink)
from getting all over the place.
