Sustainability Report 2013 – Lek d.d. Environment 36 2.6.2 Emissions from waste incinerators and co-incinerators At the Lendava site, the waste incinerator operates, mainly treat- ing industrial waste generated at the site. Due to the release of mycelium waste to a biogas plant for treatment, its scope of operation has diminished. During the incineration process, con- trolled via a control system, flue gas parameters are regularly measured. The set limit/alarm values prevent the waste inci- neration process from running outside the permissible limits. By incineration of waste and natural gas as supporting fuel, technical steam is obtained. At the Menge‰ site, thermal oxidation of industrial fumes is car- ried out in one of the four combustion plants using natural gas as a primary source of energy. By co-incineration of natural gas and non-halogenated solvents of high purity and calorific potential, technical steam is obtained. Emission monitoring is regularly performed at all the emission release points. In 2011, permanent emission measurements were provided on the waste solvent co-incinerator for the parameters prescribed in the environmental permit. As operators of industrial complexes performing single or multiple activities covered by Regulation (EC) No. 166/2006, the Lendava and Menge‰ sites have the obligation of reporting the volume of releases to the European Pollutant Release and Transfer Register (E-PRTR). 2.6.3 Sulphur dioxide (SO 2 ) 50 The volumes of SO 2 emissions at our sites have always been low, and were mainly generated by the devices for the thermal treatment of volatile organic compounds. In 2011 and 2012 the emission monitoring performed at all of our sites showed a level of almost zero, also in 2013, the total SO 2 emissions was below 10 kg. This was confirmed by a supplier’s statement that the content of sulphur in natural gas is practically non-existent. 2009 t 0.11 0.03 0.03 0.00 0.17 0.05 2010 t 0.12 0.01 0.00 0.00 0.13 0.04* 2011 t 0.00 0.01 0.00 0.00 0.01 0.003* 2012 t 0.00 0.0001 0.00 0.00 0.0001 0.0000 2013 t 0.00 0.0004 0.0029 0.006 0.009 0.002 Year Unit Lendava Ljubljana Prevalje Menge‰ Lek (skupaj) Efficiency (Lek) kg of SO 2 /t product) Table 14: Sulphur dioxide emissions (SO 2 ) 51 * Changed efficiency data for SO 2 for Lek as a result of changed data on production output for the Ljubljana site. The values of SO 2 emission volumes by year are based on the data on their concentration at individual measuring points and on the time of device operation. 2.6.4 Nitrogen oxides (NO x ) 52 At Lek, a Sandoz company, nitrogen oxide emissions arise mainly from incinerators and co-incinerators, burning devices and to a lesser extent the manufacture of nitrooxine at the Men- ge‰ site. At all the sites, regular emission monitoring is carried out. In 2013, the total volume of nitrogen oxide emissions increas- ed slightly (by 6%), compared to 2012, however it remains below statutory values. A decline in nitrogen oxide emissi- ons was recorded at the Ljubljana site, whereas the Menge‰ and Prevalje site a level similar to that in the previous year was maintained. The Lendava site recorded a 39% increase in emissions which is however, within the variability of the measurement process itself. 50 EMAS Core Indicator, RC KPI 8, GRI Indicator G4-EN21 51 EMAS Core Indicator, RC KPI 7, GRI Indicator G4-EN21 52 EMAS Core Indicator, RC KPI 8, GRI Indicator G4-EN21 53 EMAS Core Indicator, RC KPI 7, GRI Indicator G4-EN21 2009 t 10.14 0.78 8.72 1.38 21.02 0.007* 2010 t 9.14 1.30 16.36 1.36 28.16 0.009* 2011 t 7.17 1.33 15.06 1.40 24.96 0.007* 2012 t 7.58 2.33 9.94 1.27 21.12 0.006* 2013 t 10.57 1.04 9.35 1.43 22.39 0.006 Year Unit Lendava Ljubljana Prevalje Menge‰ Lek (Total) Efficiency (Lek) t NO x /t product) Table 15: Emissions of nitrogen oxides (NO x ) 53 * Changed efficiency data for NO for Lek as a result of changed data on production output for the Ljubljana site.
