Zusammenfassung: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. La invención se relaciona con un proceso para tratar un material que contiene asbesto, el cual posibilita que el asbesto se transforme a productos inertes (es decir, no peligrosos para la salud humana) que pueden reutilizarse posiblemente como materias primas para procesos industriales subsecuentes o como productos industriales directamente comercializables. El proceso comprende las etapas de preparar una solución/suspensión ácida al someter un material de desecho de la industria alimentaria a crecimiento y/o fermentación bacterianos y fúngicos mixtos, y tratar un material que contiene asbesto con la solución/suspensión ácida obtenida a partir de la fermentación mixta a una temperatura de 120 a 170 °C y una presión de 200 a 1,000 kPa (2 a 10 bar).
