The share of recycled water, however, is on the increase at other sites as well. At the Menge‰ site, a three-level cooling water system ope- rating at different temperature regimes enables the water from one system to be fed into a higher-temperature system, while one portion of water (spill) is discharged into the sew- age system. The quantities of reused water vary greatly and depend on individual processes, so they cannot be accurately calculated on the basis of the existing data cap- ture method. Based on relevant calculations, it has been assessed that almost the entire cooling water volume is re- used at least twice. At the Lendava site, the project of fermentation production expansion by installing two additional fermentation vessels was performed with the best available techniques (BAT). As the cooling cycles are of the closed-loop type, the consumption of well cooling water will not rise despite the increased production volume. 2.5.1 Waste management 46 Due to a changed data collection methodology (see Item 1.4.1) changes in the volumes of waste for the previous year occurred. Consequently, a direct comparison of waste vo- lumes generated in 2011 and 2012 with the volumes in the previous years is not entirely appropriate. The data for 2011 and 2012, however, is comparable in consideration of the fact that mycelium waste is no longer incinerated in our incinera- tion plant, and consequently became the subject of reporting in 2012 and 2013. Mycelium waste, however, accounts for more than 97% of all waste at the Lendava site and near- ly 74% of the total waste from the entire operation of Lek, a Sandoz company. The major part of the mycelium waste is water therefore we are investigating the possibility of centrifug- ing the waste before being removed to a biogas plant. This would reduce the volume of waste and save on fuel consump- tion for transport (and consequently reduce CO 2 emissions as well). In 2013, disregarding biodegradable waste (mycelium, waste fennel plant, waste Echinacea plant, green garden waste) the effective waste management was improved by nearly 5%. Because of two technologically different forms of production (bio-fermentative production of active ingredients and pack- aging of finished dosage forms), the Lendava production site faces different types and quantities of waste. By changing the product range, major quantitative fluctuations occur in packaging. At the Menge‰ site, more than 80% of the total waste is accounted for as hazardous waste, particularly liquid waste solvents and solid hazardous waste. One portion of this waste is reused as an energy source. The remaining quantity is released to authorized companies for environmentally acceptable disposal. Despite increasing production outputs, changes in the pro- duction structure and the rising number of employees, the relative quantities of non-hazardous waste have remained at almost the same level over the past 5 years. As already mentioned, it applies for all quantitative data presented below that since 2011, only data for the volume of waste released for treatment outside the production site, has been reported. 2.5 Waste 2009 t 3,343 1,646 5,234 573 10,796 2010 t 3,801 1,851 4,907 535 11,094 2011 t 1,432 1,800 4,392 590 8,214 2012 t 11,374 2,210 4,904 676 19,164 2013 t 24,258 2,230 4,670 698 31,856 Year Unit Lendava Ljubljana Prevalje Menge‰ Lek (Total) Table 11: Volumes of waste generated in tonnes
