Abstract
Abstract Portable hazardous waste containers can be used both for storage and transportation. Waste from an unsatisfactory container, an open pit, or a process stream can be placed in the container, which can then be shipped, if necessary, to a disposal site and then buried in a landfill. By using proper materials and container dimensions, a single container can satisfy the separate regulatory requirements for waste storage and transportation.
