  • Method for refuse disposal in solution-mined salt cavities
    Patent number: 5433553
    Abstract: A method for Refuse Disposal in Solution-Mined Salt Cavities is described. Firstly, crush municipal refuse to a particulate size of less than one inch. Secondly, compact a mixture of particulate refuse and brine into cakes less than one inch in thickness at densities in excess of 77 pounds per cubic foot. Thirdly, mix the cakes with brine to form a slurry with a minimum volume ratio of 2 portions brine to 1 portion cakes. Fourthly, inject the slurry into a brine filled salt cavity, whereby the cakes, being denser than the brine, settle to the bottom of the salt cavity.
