In April Ragn-Sells Estonia sent 4 tonnes of oil shale ash to a Finnish laboratory, where industrial tests of calcium carbonate production technology now will start. This is the last pre-phase of the scientific research before the design of the plant and the start of the production scheduled for 2025 according to the current timetable.
The cooperation with Tallinn Technical University and the University of Tartu enables the project to now begin working on the important industrial tests, where the details of calcium carbonate production in large volumes, up to 1 million tonnes, are determined.
- If until today we have improved the technology and thereby produced a few kilos of calcium carbonate from the ashes, now we aim to increase these quantities to hundreds of kilos. It gives us an idea of the specifics of industrial production and prepares us for the final design of the plant. We are very grateful to our partners from the Estonian universities and we look forward to continuing cooperating in the future, says Alar Saluste, project manager Ragn-Sells Estonia.
