Waste stabilisation by lime admixtures using jet-grouting technology

The pilot study on a municipal solid waste landfill is under way. In order to chemically immobilize the waste jet-grouting has been executed on the trial field on the landfill. Three groups of three columns cca 4 m long have been formed using cement and lime mixtures. Samples were taken from the grouted part of the landfill as well as from nontreated waste. The preliminary test results are presented and some general conclusions are drawn.
