Sustainability Report 2014 Lek d.d.

Sustainability Report 2014 – Lek d.d. Environmen 46 Through increasing knowledge of chemical substances Lek started – even before the respective Slovenian and EU laws were implemented – to research the impact of active phar- maceutical ingredients potentially entering wastewaters as a result of our operations. From there, they pass through wastewater treatment plants into surface waters. However, it has been established that only a small percentage of APIs present in the wastewaters are generated by the production of pharmaceuticals and that the major part results from the final users of pharmaceutical products. 66 Ecotoxicity data of APIs are regularly reviewed and evalu- ated, and proper action is taken.

In 2014, we recorded a slight decrease in the chem- ical oxygen demand parameter (1%) on account of the Menge‰ site. The Prevalje and Ljubljana sites together contribute to less than 3% of total wastewater pollution with organic impurities. Chemical oxygen demand, total phosphorus compounds and total nitrogen compounds in wastewaters also consti- tute parameters for the calculation of the environmental fee. The highest impact, accounting for more than 80%, is asso- ciated with chemical oxygen demand, whereas phosphorus and nitrogen compounds each represent about 10% of the pollution. Wastewaters and the content of all the three parameters are constantly monitored by the authorized monitoring authori- ties. Monitoring is carried out three to six times a year, depending on the volumes of wastewaters at the respective site. 63 RC KPI 15 64 RC KPI 16 65 RC KPI 14 66 GRI Indicator G4-EN27, G4-DMA
