There is a system set up so that customers may pour out their leftover coffee into it, which then is processed, filtered, and added to a nice decorative fountain in the coffee shop. The fountain functioning is dependent on customer's doing this collectively, so the fountain is bigger and better as more customer's use it. Then they can simply throw their cup into the bin set up next to the fountain. Pouring out the liquids allows for successful recycling of the bin's contents. The fountain would be emptied each night as the shop closes, so that it's growth could be seen and enjoyed each day while also not overwhelming the fountain's capabilities.
