The largest circular economy project in Northern Europe

Nearly 600 million tonnes of oil shale ash have been deposited in Ida-Viru county. Ragn-Sells has developed a solution to turn these ashes into ultra-pure calcium carbonate while simultaneously capturing large amounts of carbon dioxide into the material.

Circular economy success story

Imagine a world where waste is no longer a problem but a valuable resource — upcycling of oil shale ash is a revolutionary step towards realizing this dream.

Upcycling of ash hills

Climate-neutral production process

Explore oil shale ash upcycling — a process that turns industrial waste into a valuable raw material while reducing extraction of new materials.

Production

From waste to valuable products

Our innovative approach turns oil shale ash into ultra-clean products such as climate-neutral calcium carbonate and lime fertilizer.

Products

EUROPEAN UNION SUPPORTS ESTABLISHMENT OF DEMO FACTORY IN IDA-VIRUMAA
The purpose of the demo factory is to validate the final production process and technology before the completion of the final commercial factory. The output of the demo factory will be directed to end users to test product properties and design final products based on development cooperation. The European Cohesion Fund supports the establishment of a demo factory for oil shale ash valorization with up to 1,327,261.50 Euros.

THE EU COHESION FUND CO-FINANCES PRODUCT DEVELOPMENT OF CALCIUM CARBONATE VALORIZED FROM OIL SHALE ASH
The EU Cohesion Fund finances the conduct of scientific and applied research on oil shale ash valorization. The purpose of the support is to promote the product development of precipitated calcium carbonate. The maximum amount of support is
1 004 229,00 Euros.
