Ida-Viru County: where ash hills are turned to climate positive calcium carbonate (PCC)

At present, energy in Estonia is still mainly produced from oil shale because the alternatives do not yet generate the required volumes. The production of oil shale energy generates up to 1 million tonnes of ash waste every year and by valorising this, we can contribute significantly to the reduction of the environmental footprint of our energy generation as a solution which is necessary today. A cleaner living environment in Ida-Viru County and throughout Estonia.
