In cooperation with Engineering Bureau STEIGER and University of Tartu scientists, Ragn-Sells has taken core samples from an oil shale ash hill in Ida-Viru County for the purpose of gathering information that will support further research into valorizing the older layers of the deposited ash. The same consortium is also implementing a project for valorization of newly generated ash.<\/strong> 

Ragn-Sells project manager Alar Saluste says the technology and research for valorizing newly generated ash are in a fairly mature phase, but possible applications also need to be found for the hundreds of millions of tonnes of ash deposited in previous decades. \u201cThe next step is to conduct investigations into the historical ash deposits to chart the untapped possibilities. One future aim would certainly be to find circular-economy-based ways of using these extremely large volumes of waste,\u201d added Saluste 

University of Tartu research fellow Riho M\u00f5tlep said attempts to find new uses for the waste generated by the oil shale energy sector have so far focused on \u201cfresh\u201d ash. \u201cBut the older deposits also hold promise when it comes to processing and enhancing the value of the material. And so this newly launched applied research project started by boring into and taking samples for the first time from the untouched core part of the ash deposit; which will give us information about whether the ash, after lying untouched for decades, can be used as a valuable raw ingredient,\u201d said M\u00f5tlep.  

Ragn-Sells AS established a subsidiary, R-S OSA Service O\u00dc, to administer the oil shale ash valorization project launched five years ago. The company has led the creation of a scientific consortium in which, among others, researchers from the University of Tartu and the Tallinn University of Technology are involved in fundamental and applied research. Recently, the Archimedes Foundation came aboard as a co-financing provider for the research.
