ABSTRACT Method of disposal or temporary storage of waste material. A method of disposal or temporary storage of fine particulate solid waste material or a mixture of such solid material with liquid comprises pumping the solid material entrained in liquid through a pipeline by means of a piston pump into a natural or artificial dump space above ground or below ground. To pump fine grained waste materials, for example dusty or paste-like and sludge-like waste materials, without incurring problems regarding the entrainment liquid and to prevent, in the case of underground storage, the production of a geologically insufficiently stable packing in a natural or artificial cavity, a high-consistency mixture containing less than 20% by weight of liquid, which is generally water, is pumped into the space by means of the piston pump.
