I have registered with Think Recycle for the Conquer Cancer Ride. I will be collecting used cell phones, laser cartridges and ink jet cartridges. I send them to Think Recyle and they issue payments to the Princess Margaret in my name. They recycle 100% of all items received and fund the planting of a tree for every 10 items submitted. Definitley a win-win program. Remember to keep you old cartridges and send me an e-mail to pick them up.
