Staples has an extensive program for recycling office supplies and electronics. With a Staples Rewards card, you can also receive £1.30/$2 back for every ink cartridge you recycle there for up to 10 cartridges each month. If you recycle significantly more than 10 cartridges per month--such as from your work or school--Staples can work with you to handle the larger amount.
Navigate to the Staples website, click on "Locate store" and type in your address or city. Select the store from the list that is located nearest to you.
Place your cartridges to be recycled in sealed plastic bags to prevent any remaining ink from spilling.
Take the cartridges to Staples and turn them in for recycling at the customer service desk.
