Here's something I didn't know about: recycled printer cartridges. The last time I bought a new cartridge, I selected one of the cheaper ones available at Wal-Mart. It bore the Pelikan logo, which impressed me because Pelikan is a noted manufacturer of fountain pens (not that success at fountain pen manufacturing necessarily leads to success in printer cartidge manufacturing, but, hey.). I finally opened the cartridge this weekend, and found a plastic business-reply envelope inside to send my old cartridge in for recycling. That struck me as pretty cool. Reusing and recycling is nifty.
