In the game, each player takes on the role of a recycling company, trying to clean up the city. There are four types of items that can be collected: paper, plastic, aluminum, and glass. There are four corresponding recycling plants where you can deposit your collected items and pick up more. If you are the player that contributes an item or items that equals a total of four or more, then you get to pick up a scoring token from that particular recycling plant.
