The chemical composition and leachability of metals were determined in the investigated samples. The ashes were vitrified in a thermal plasma process and their chemical stability was tested to determine whether the ashes can be disposed safely into the environment, specifically onto surface soil. The heavy metal leachability tests proved that the products after vitrification were more stable than non-vitrified waste making it more suitable for disposal into the environment.application/pdfenArticle
