We separately monitor greenhouse emissions and emissions from immobile devices. Of the latter emissions, VOCs and dust are the most important. Emission metering points are established on individual manufacturing devices and lines where the presence of emissions of VOCs, dust particles and other substances is expected in the exhaust air. At these points, the content of a specific substance and/ or dust in the air is measured, and samples for analysis are collected. For all the outlet ducts measured, assessments of substance and/or dust emissions have been made as pre- scribed. To reduce organic substance emissions, we use devices for exhaust air cleaning such as thermal gas incinerators, ad- sorbers, gas washers, and other. In 2012, the Ljubljana and Menge‰ sites witnessed the conclusion of a major project of replacing the existing thermal gas incinerators with two de- vices of higher energy efficiency, which are able to operate without additional fuel (natural gas) within a specific range of solvent concentration in the waste air. To remove dust parti- cles before the exhaust air outlet, two H.E.T. filter units are installed, capable of trapping 99.95% of dust particles ran- ging from 0.1 – 0.3 µ m in diameter. Air emissions from devices for the production of finished do- sage forms and APIs are divided into VOC emissions evalu- ated in accordance with the VOC Directive, and emissions of substances evaluated on the basis of the Industrial Emissions Directive. Lek complies with all relevant regulations in this area. Based on the results of periodic measurements, balance of sol- vents used, assessment of emission dispersion, and other data, we prove the conformity of total VOC emission values with the emission limit value expressed as percentage of organic sol- vent input. For new devices this value amounts to <5%, for exi- sting devices it is <15%, whereas VOC emissions in captured waste gases do not exceed the limit concentrations of 20 mg C/m 3 . For the existing device, furnished with a device for waste gas removal, the limit values of 50 mg C/Nm 3 for incineration of waste gas, and 150 mg C/Nm 3 for other methods of waste gas removal will become effective as of 31 December 2013. Furthermore, Lek maintains its compliance with the limit value for total dust, amounting to 150 mg/m 3 and with the limit value for the mass flow of total gas in excess of 0.2kg/h, which amo- unts to 20 mg/m 3 . When using thermal incinerators for emission control, we not only measure VOCs quantified as total organic carbon (TOC), but also the emissions of nitrogen oxides and carbon monoxi- de (LV = 100 mg/m 3 ). According to the stated parameters, these devices comply with statutory requirements as well. 2.6 Air emissions 39
