Abstract
Waste products which are to be disposed of by burial, are mixed with a hardening substance in bags which are wrapped around circular or approximately circular frames. The circular shape enables efficient mixing. The bagged frames are placed in a rectangular mould and the bags then filled and the contents mixed by stirring; the wrappings are released and the mixes settle into the shape of the rectangular interior of the mold and fill it, thus adopting the most efficient storage shape.
