as a method of hospital waste management, generates

off-gas cleaning residues with high levels of heavy metals, inorganic
salts and other organic compounds. Many references in
international literature characterize the bottom ash as either dangerous,

waste materials with codes 19.01.13 and 19.01.07, respectively
