31 Environment 35 GRI Indicator EN10 36 EMAS Core Indicator, GRI Indicator EN22 2.4.3 Recycling and reuse 35 Recycled water is mostly reused for the cooling of processes, mainly at the Menge‰ site. The share of recycled water, howe- ver, is on the increase at other sites as well. At the Menge‰ site, a three-level cooling water system opera- ting at different temperature regimes enables the water from one system to be poured into a higher-temperature system, while one portion of water (spill) is discharged into the sewa- ge 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 capture method. Based on relevant calculations, it has been assessed that al- most the entire cooling water quantity is reused at least twice. At the Lendava site, the project of fermentation production expansion by installing two additional fermentation vessels was performed with the best techniques available. As the cooling cycles are of the closed-loop type, the consumption of well coo- ling water will not rise despite the increased production volume. At the Prevalje site, we used the wastewater generated in the process of water preparation for cooling purposes, thereby reducing the fresh water consumption in the cooling towers by 30%. 2.5.1 Waste management 36 Over the past 5 years, the relative volumes of generated waste (t of waste / t of product) have been diminishing due to manufacturing process optimizations, whereas the increa- sing production volumes have resulted in an increase in the absolute waste volumes. Due to a changed data collection methodology (see Item 1.4.1), changes in the volumes for previous years occurred. Consequently, a direct comparison of waste volumes genera- ted in 2011 and 2012 with the volumes in the previous years is not entirely appropriate. The data for 2011 and 2012, howe- ver, is comparable in consideration of the fact that mycelium waste is no longer incinerated in our incineration plant, and consequently became the subject of reporting in 2012. At the Lendava site, the types and volumes of waste differ as a result of two different production processes (biofermen- tation production of APIs, and packaging of finished dosage forms). The packaging process is characterized by major va- riations in quantity that depend on the product changeover. At the Menge‰ site, more than 80% of total waste is accoun- ted for by hazardous waste, particularly liquid waste solvents and solid hazardous waste. One portion of this waste is re- used as an energy source. The remaining quantity is relea- sed 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. In 2011, the reporting methodology for waste changed (see Item 1.4.1) due to the fact that the waste disposed of at the Lendava site by incineration, and at the Menge‰ site by co- -incineration with energy utilization, is no longer taken into account. Reports only cover the volume of waste released for treatment outside the production site. Given the change in the final waste disposal destination, the new method of data recording based on the Novartis' methodology is the major cause for the increase in the total waste figures for 2012. According to the methodology, mycelium waste pre- viously incinerated in the site's own incineration plant was not included in the report. Since 2012 when it was first re- leased to a nearby biogas plant for treatment, it has been covered by the report, and strongly impacts the waste figures reported. 2.5 Waste 2008 t 3,663 1,457 4,474 535 10,129 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** Year Unit Lendava Ljubljana Prevalje Menge‰ Lek (Total)* Table 11: Volumes of waste generated (in t) * The data for 2010 and 2011 differs from the data reported in the previous report due to the reconciliation of decimal rounding off. ** Volume of waste released for treatment outside the production site.
