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 col- lected. For all the outlet ducts measured, assessments of sub- stance and/or dust emissions have been made as prescribed. To reduce organic substance emissions, we use devices for thermal oxidation of waste gas, adsorbers, gas washers, and others. Air emissions from devices for the production of finished dos- age forms and APIs are divided into VOC emissions evalua- ted in accordance with the VOC Directive, and emissions of substances evaluated on the basis of the Industrial Emissions Directive. Based on the results of periodic measurements, balance of solvents used, assessment of emission dispersion, and other data, we prove the conformity of total VOC emission values with the emission limit value expressed as a percentage of organic solvent input. For new devices this value amounts to <5%, for existing devices it is <15%, whereas VOC emissions in captured waste gases do not exceed the limit concentra- tions of 20 mg C/m 3 . For the the existing device, equipped with a device for waste gas removal, the limit values of 50 mg C/Nm 3 for thermal oxidation of waste gas and 150 mg C/Nm 3 for other methods of waste gas removal applied until the end of year 2013. Lek, a Sandoz company, 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 0.2 kg/h, which amounts to 20 mg/m 3 . When using devices for thermal oxidation, we not only meas- ure VOCs quantified as total organic carbon (TOC), but also the emissions of nitrogen oxides and carbon monoxide (LV = 100 mg/m 3 ). According to the stated parameters, these devices comply with statutory requirements as well. 2.6 Air emissions 49 RTO device in Prevalje Strict waste segregation in laboratories A new device for treatment of atmospheric emissions at the Prevalje site We monitor the expansion of production with systematic efforts for simultaneous introduction of the state-of-the-art and most environmentally friendly technology available. At the Prevalje site, the existing air emission treatment devices (adsorbers) were replaced in 2013 with a more effi- cient and economical device for treatment of waste air from coating drums. This system for regenerative thermal waste air oxidation (RTO) operates without adding any natural gas into the combustion chamber already at concentrations between 1.2 to 1.5 g of solvents per m 3 of waste air.
