Heavy and dense materials such as rocks and metal work their way into a junk trap at the bottom of the repulper where they are periodically removed. The junk trap is a collection chamber with two valves. The upper valve is normally open to the repulper, while debris collects in the chamber. Periodically, the chamber is isolated from the repulper by closing the upper valve, and the lower valve is opened to release the contents. The junk trap contents may be dewatered as they are conveyed from the trap, or they may dewater in their collection bin. Due to its nature, after it gravity drains, this rejects stream has a very low percentage of moisture and fiber. The heavy trash is sent to landfill.
