One Person’s Trash Customers log on to recyclebank.com to see how much they recycled, how many reward points their refuse is worth, and how their carbon footprint is affected. Some towns using RecycleBank have more than doubled their recycling rates by weight — diverting waste from landfills and conserving tons of valuable raw materials.
The Tell-Tale Arm RecycleBank outfits each home in a partner city with a special recycling bin that has a radio-frequency-identification (RFID) tag embedded in it. On trash day, a robot arm on the garbage truck weighs how much material is recycled, and then an onboard computer relays that info wirelessly to RecycleBank headquarters.
