The mixtures of halogenated waste solvents account for only 2 to 5% of total hazardous waste in Menge‰. By means of co-inciner- ation with natural gas, 25 to 30% of the annual quantity of non-halogenated solvents is removed (no transport required, lower fuel consumption and CO 2 emissions). The energy obtained is utilized for manufacturing purposes to prepare industrial steam. At the Ljubljana site, out-of-date products account for a considerable portion of the generated hazardous waste. The inventory management method in place, however, makes it impossible to reduce their volume. Since 2011, however, we have performed intensive segregation of the waste pack- aging of hazardous substances (also in case a hazardous substance is only present in traces) which we release for incineration with energy recovery. In 2014 we considerably reduced volumes of hazardous waste at the Prevalje site by various measures. Reducing hazardous waste at the Lendava site was due to the result by the accredited laboratory showing that slag from the incinerator does not have hazardous properties. Waste was therefore diverted to non-hazardous waste. Increasing production outputs and changes in the product range towards technologically more advanced products manufactured at the Menge‰ site in smaller quantities by using complex techniques also result in increased abso- lute quantities of hazardous waste and quantities per unit of product. We are limiting this growth by implementing environmentally advanced manufacturing solutions and measures to reduce the volume of waste of this type.
