After a series of green investments, such as building a warehouse according to sustainability and energy efficiency principles, as well as the installation of solar panels and LED lighting, HEINEKEN Croatia has decided to take another major step in the field of environmental protection. We started using biogas, which is produced as a by-product of wastewater treatment, in our brewery in Karlovac – primarily as thermal energy for production, and in a smaller volume for heating.
Thanks to this initiative, we have reduced the consumption of natural gas for heating, as well as saved energy. In addition, we have decreased carbon dioxide emissions by 110 tons annually, which is equal to putting 50 cars out of traffic. These very positive results in the field of sustainability and environmental protection have been achieved thanks to a new investment – a pipeline that distributes biogas from the wastewater treatment plant to the boiler room, where the gas is burned, producing thermal energy used for heating of the brewery. Aside from using another renewable energy source, the company has also shown that it is responsibly and rationally re-using waste materials.
