title: Toxicity and hazardous properties of solvent base adhesive wastes.
abstract: In this work, the hazardous properties of solvent base adhesive wastes generated in the footwear manufacturing process have been studied. The characterisation procedures and criteria used are those contained in the legal documents European Union Council Decision 94/904/CE and October 13th Spanish Ministerial Order. The properties studied were the following: flash point, reactivity (gas generation), ecotoxicity, main contaminants extracted by the leaching process and main harmful substances contained in wastes. An additional study of the relationship between flash point and solvent concentration in waste was carried out for polyurethane-acetone and neoprene-toluene systems. The wastes considered were metal containers with remains of dry or semi-dry adhesive. The results obtained show that the presence of solvent in wastes confers on them hazardous characteristics (flash point and harmful composition) depending on the solvent type and its concentration.
