OUR MODEL: WHAT MOVES AND WHY
Conveyor Belt: It pulls the recycling along so that workers can pull off anything that isn’t supposed to be there and bring the rest to the balers. Our conveyor belt is motorized.
Wheel and axle of the two trucks: The wheels move so the truck can move.
Inclined plane at the recycling plant: It acts as a ramp for sorted materials to slide down.
Lever on the back door on the garbage truck: The door opens with a lever so the workers can put garbage and recycling into the truck.
Pulley on the magnetic belt: the pulley works by someone turning a handle that causes the belt to turn so that cans can attach to the magnetic belt and fall into the metal bunker.
Levers on the doors and windows: The doors and windows open on their levers so that air or people can pass through.
