An improved means and method for shipping industrial sized quantities of hazardous concentrates which simplifies compliance with current environmental protection regulations. The method includes the steps of loading a collapsible shipping container with a collapsible bag which is partially filled with a liquid or particulate concentrate of a potentially hazardous material, collapsing the bag before inserting it into the shipping container. The container itself is then collapsed, sealed and shipped to the user. Upon arrival, the user erects the container, unfolds and fills the bag with a solvent such as water to fill the container and serve as a storage facility. The diluted or dissolved product is then drawn from the container as required until the container is empty. The user then collapses the bag and the container for return to the sender. As a result, no permanently installed storage facility need be cleaned. The container is configured to form a generally planar storage well at a lower end thereof to store the bag and a reinforcing tray may be provided to enclose the collapsed bag.
