The PASS Box™ is an ABS certified intermodal 20' container specially designed to transport dry bulk goods. It promises to cut out many of the logistical challenges present in traditional dry bulk aggregate transportation methods such as trans-loading facilities and silo storage. The containers can be filled at the source (whether a Chinese proppant factory or a Wisconsin quarry), sealed (airtight and watertight), and delivered and stored (they can stack up to eight units high) directly at the final destination. Four of the twenty-foot containers can be transported on one rail car, which (when combined) would hold about the same amount of material as a railroad hopper car.
