Due to the re- lease of mycelium waste to a biogas plant for treatment, its scope of operation diminished. During the incineration pro- cess, controlled via a control system, flue gas parameters are regularly measured. The set limit/alarm values prevent the waste incineration process from running outside the permissi- ble limits. By incineration of waste and natural gas as suppor- ting fuel, technical steam is obtained. At the Menge‰ site, thermal oxidation of industrial fumes is carried out in one of the four combustion plants using na- tural 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 para- meters 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 repor- ting the volume of releases to the European Pollutant Release and Transfer Register (E-PRTR). 2.6.3 Sulphur dioxide (SO 2 ) 40 The volumes of SO 2 emissions at Lek sites have always been low, and were mainly generated by the devices for the thermal treatment of volatile organic compounds. 2008 t 0.10 0.04 0.02 0.00 0.16 0.03 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 0.02 2011 t 0.00 0.01 0.00 0.00 0.01 0.002 2012 t 0.00 0.0001 0.00 0.00 0.0001 0.0000 Year Unit Lendava Ljubljana Prevalje Menge‰ Lek (Total) Efficiency (Lek) (kg of SO 2 /t of product) Table 14: Sulphur dioxide emissions (SO 2 ) 41 * The data differs from the data in the 2011 report due to the reconciliation of the sum total of decimals rounded off. In 2011 and 2012 the emission monitoring performed at all of our sites showed a level of almost zero. This was confirmed by a supplier’s statement that the content of sulphur in natural gas is practically non-existent. The values of SO 2 emission volumes by year are based on the data on their concentration at individu- al measuring points and on the time of device operation. 2.6.4 Nitrogen oxides (NO x ) 42 Nitrogen oxide emissions mainly arise from incinerators and co-incinerators, burning devices and to a lesser extent the manufacture of nitrooxine at the Menge‰ site. At all the sites, regular emission monitoring is carried out. In 2012, the total volume of nitrogen oxide emissions decre- ased further, remaining below the statutory values. A decline in nitrogen oxide emissions was recorded at the Prevalje and Menge‰ sites, whereas the other two sites maintained a level similar to that in the year before. 2008 t 9.30 1.14 10.82 1.36 22.62 0.005** 2009 t 10.14 0.78 8.72 1.38 21.02 0.006 2010 t 9.14 1.30 16.36 1.36 28.16* 0.006** 2011 t 7.17 1.33 15.06 1.40 24.96 0.005 2012 t 7.58 2.33 9.94 1.27 21.12 0.004 Year Unit Lendava Ljubljana Prevalje Menge‰ Lek (Total) Efficiency (Lek) (t of NO x /t of product ) Table 15: Emissions of nitrogen oxides (NO x ) 43 * The data differs from the data in the 2011 report as a result of the adjustment made due to incorrect decimal rounding off. ** Changed efficiency data for NO x for Lek as a result of changed data on production output for the Ljubljana site.
