Bulk container

Abstract

A waste dust containment system includes a bag and a waste-dust fill chute. The bag is formed to include an interior region for storing dust. The waste dust fill chute conveys waste dust generated in a factory into the interior region of the bag. Once filled with wasted dust, the bag is delivered to a waste-dust disposal site away from the factory.
