Abstract: The invention relates to a process for treating an asbestos-containing material, which enables the asbestos to be transformed into inert products (i.e. not hazardous to human health) that can possibly be reused as raw materials for subsequent industrial processing or as directly marketable industrial products. The process comprising the steps of preparing an acidic solution/suspension by subjecting a food industry waste material to mixed bacterial and fungal growth and/or fermentation, and treating an asbestos-containing material with the acidic solution/suspension obtained from the mixed fermentation at a temperature of 120-170° C. and pressure of 2-10 bar.
