You are standing in another section of the large cavern. There are dim lamps lighting the room, and huge piles of batteries cover most of the floor. You see a huge machine behind the batteries. The machine must be on because it is making a loud buzzing sound. When you move closer to investigate the machine, you can see a sign on it that reads "Curbside Recycling Company." You also see several green buttons labeled "Paper," "Plastic," "Glass," "Six-pack Rings," and "Aluminum" next to an arrow pointing to an opening in the machine. The arrow reads "Place Recyclable Products Here." Tire tracks lead away from the machine and through the cavern to the north.
