40 Active Environmental Policy Air emissions 46 Emission metering points are established on individual man- ufacturing devices and lines where the presence of emis- sions of VOCs, dust particles and other substances is ex- pected in the exhaust air. At these points, measurements of the substance and/or dust content in the air are made, and samples for analysis are taken. For all the outlet ducts meas- ured, assessments of substance and/or dust emissions have been made as prescribed. We distinguish between green- house emissions and emissions from immobile devices; of the latter emissions, VOCs and dust are the most important. Organic substance emissions are effectively reduced by means of devices for exhaust air cleaning such as thermal gas incinerators, adsorbers, gas washers, and other. Emissions from waste incinerator Emissions from this source are generated at the Lendava site, where a waste incinerator operates, and at the Menge‰ site, where co-incineration of natural gas and waste non- halogenated solvents is carried out. For the operation of the devices, environmental permits have been obtained. At the Lendava site incinerator, mainly incineration of waste from production on the site is carried out. Waste waters gen- erated in the incineration process are discharged into the industrial sewage system, whereas flue gases are directed through the flue gas purification section into the atmosphere. During the incineration process, controlled via a control sys- tem, flue gas parameters are regularly measured. The set limit/alarm values prevent the waste incineration process from running outside the permissible limits. In case of any deviation from the prescribed temperature, the waste dis- pensing system is halted automatically. At the Menge‰ site, most of the air emissions are generated by four burning devices which utilize natural gas as the pri- mary source of energy. In one of these devices, thermal oxi- dation of fumes originating from the manufacturing process is performed. For the production of industrial steam, natural gas and non-halogenated waste solvents of extreme purity and high calorific value are burnt simultaneously. Emission moni- toring is regularly performed at all the emission release points. 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 report- ing the volume of releases to the European Pollutant Re- lease and Transfer Register (E-PRTR). Sulphur dioxide (SO 2 ) SO 2 emissions originate from burning devices and devices for the thermal treatment of volatile organic compounds. Emission volumes are small, and the emission trend shows no major os- cillations. At the Lendava site, waste incineration is the major source of this type of emissions, which also contain sulphur due to their organic nature. At the Menge‰ and Ljubljana sites, SO 2 emis- sion results from the presence of sulphur in the natural gas used in the burning devices (Menge‰) and/or in the devices for thermal treatment of waste gases (Ljubljana). The values of SO 2 emission volumes by year are based on the data on their concentration at individual measuring points and at the time of device operation. Emission monitoring is carried out at all sites.
