In 2017, 42% of the energy used in our EU and Swiss plants came from renewable sources and we have 8 sites using electricity from co-generation. Last year, 10 out of our 26 plants in the EU and Switzerland were using 100% renewable and clean electricity and during 2018 more began to make the switch. Our Edelstal plant in Austria, for example, has a long-term renewable-electricity supply contract for 100% of its electricity. This prevents almost 4,000 tons of CO2 emissions each year.
Following 2025 Sustainability Commitments our Business Unit has started using renewable energy in Neptunas plant as well. As of this year we are using 100% clean electricity that comes from Kaunas Algirdas Brazauskas Hydroelectric Power plant located in Lithuania.
Nearly 50% of the electricity we use in 2019 in Polish 3 plants comes from renewable energy sources. Installation of heat recycling from treated waste. In cooperation with the Carrier company we installed in our facility a heat pump, which is to collect the heat from the treated waste, and then use the heat restored for heating purposes, including the heating of the entire building of the waste treatment plant, i.e. the cloakroom of the warehouse workers, cloakroom of the waste treatment plant workers, steering room of the waste treatment plant, lab and technical rooms.
