A container for hazardous waste is formed of corrugated cardboard that is coated on both sides with fiberglass. The carboard includes flaps that are bent prior to being coated to form triangular braces that extend along the edges of the container. The container is extremely durable, impervious to a wide range of chemicals, and economical to manufacture. In one embodiment, suitable for use where greater protection is required, a smaller container made by the same technique is lowered into a larger container of the same type, and the space between the inner and outer containers is filled with a liquid foam plastic. When the foam plastic has cured, it serves to prevent movement of the inner container with respect to the outer container, to provide thermal insulation, and to protect against shock and breakage of the inner container.
