A system and method for compressing scrap metal. The scrap metal is compressed in a portable container. The container rests on two scales that rest above the ground surface. The fullness of the container is primarily evaluated based on the weight of the container. The scrap metal is initially delivered to a static compactor (38) to which the container (42) is mated. The compactor (38) includes a ram that forces the scrap metal into and compresses the scrap metal in the container. The weight of the container is continually monitored while the container is mated to the compactor. The actuation of the ram is controlled so that, as the amount of scrap metal in the container increases, the frequency with which the ram is actuated increases. After the volume of scrap metal in the container (42) increases above a certain level, each actuation of the ram actual comprises running the ram through plural extension and retraction cycles. The weight of the container (42) is employed as the primary variable upon which the fullness of the ram is evaluated. The pressure of the hydraulic fluid that actuates the ram is also monitored. Even if the container weight is below a set weight, if the hydraulic pressure exceeds a set pressure, the container is considered full. The container has a tapered profile. Ribs extend inwardly from the inner surfaces of the panels forming the container. These features ensure that, when the container tipped, gravity provides sufficient force for drawing the compressed scrap metal out of the container.
