Electricity and Heat Energy
Since 2000, the process heat released during the sulphuric acid production process was started to be further beneficially utilized to heat the local and Kėdainiai city objects. Using special steel tube heat exchangers, the water is heated to 90°C with sulfuric acid heat and supplied to the Kėdainiai city boiler house for heating residential buildings.
With the introduction of the HRS (Heat Recovery System) system in 2007, the company generates about 250 million kWh of electricity from waste heat sources, of which about 50 million kWh is supplied to the country's electricity grid. The city is supplied with around 100 000 MWh of heat.
To produce this amount of energy, over 70 million cubic meters of natural gas would have to be burned in Lithuanian power plants and boiler houses.
This would result in 150,000 tonnes of greenhouse gas (carbon dioxide) emissions into the atmosphere.
