We are limiting this growth by implementing environmentally advanced manufacturing solutions and measures to reduce the volume of waste of this type. At the Menge‰ site, non-halogenated waste solvents, being extremely pure and having a high caloric potential, account for 85 to 95% of total hazardous waste. The mixtures of ha- logenated waste solvents account for only 2 to 5% of total hazardous waste in Menge‰. By means of co-incineration with natural gas, 20 to 30% of the annual quantity of non- halogenated solvents is removed. The energy obtained is utilized for manufacturing purposes to prepare technical 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 At the Ljubljana site, out-of-date products account for a considerable portion of the generated hazardous waste.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 packaging of hazardous substances (also in case a hazardous substance is only present in traces) which we release for incineration with energy recovery. In 2013, we introduced measures to reduce the volume of hazardous waste at all sites, except in Ljubljana. At the level of Lek, the volume was smaller by 7% compared to 2012. 2009 t 2,173 423 4,380 253 7,229 2010 t 2,619 529 3,987 211 7,346 2011 t 783 412 3,416 228 4,839 2012 t 220 572 4,111 247 5,150 2013 t 148 575 3,855 215 4, 793 Year Unit Lendava Ljubljana Prevalje Menge‰ Lek (Total) Table 12: Volume of hazardous waste in tonnes
