It takes 2.5 ounces of oil to make an inkjet cartridge. Don’t throw them out! Donate them.

Send them to Cents of Relief to support their Inking Out AIDS program.

Pick up an envelope on your next trip to Petsmart, and donate your cartridges (and cell phones) to Petsmart Charities. They’ve saved the lives of close to three million animals so far.

Or check with your local humane society, Meals on Wheels branch, PTA, or food bank to see if they accept donated inkjet cartridges for recycling.
