Ida-Viru County without ash hills

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 over 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. 

Only up to 30% of the electricity generated in Estonia comes from renewable energy sources and the rest is still largely produced from oil shale. 1The efforts for changing these shares in favour of green energy are fruitful because we started from scratch and have now achieved almost a third. However, this change is time-consuming due to the resource-intensity of the field, and we still depend on oil shale energy. The latter is criticised for its major negative environmental impacts – CO2 emissions and ash wastes. For years, people have been trying to find ways of reducing CO2 and find further uses for ash waste to reduce their impact as well. So far, development work has not led to the implementation of solutions to such an extent that it would yield really remarkable results. Until today. A technology has been developed as a result of years of research, which means that there will be no new ash hills in the future.
