The bulk material storage container includes a frame having a top portion and a bottom portion, which is supported by a plurality of rigid bars. A semi-rigid containment structure is further provided, which is supported by the frame. The semi-rigid containment structure may be formed of a plurality of interconnected or attached panels of thin steel sheets, carbon graphite or fiber reinforced plastic. Alternatively, the semi-rigid containment structure may be integrally formed of a roto-molded plastic material. The frame optionally has an opening at the top, which is sized to allow for easy removal and replacement of the semi-rigid containment structure.
