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

The detrimental impact of pesticides on non-target organisms is one of the most urgent concerns in current agriculture. Double-stranded RNAs (dsRNAs) represent the most species-specific class of pesticides to date, potentially allowing control of a target pest without effecting other species. The unprecedented target-specificity of dsRNA is due to its nucleotide sequence-specific mode of action that results in post-transcriptional gene silencing, or RNA interference (RNAi), in the target species. The development and field use of dsRNAs, via both the insertion of transgenes into the plant genome and the application of dsRNA sprays, is a rapidly growing area of research. Simu
