The Inorganic Materials Research Lab, where experienced scientist <a href=\"https:\/\/www.etis.ee\/CV\/Mai_Uibu\/est\/\" target=\"_blank\" rel=\"noopener\">Mai Uibu<\/a> works, focuses on the properties and reuse of industrial waste, including oil shale ash.\r\n\r\nIn recent years, this research has been practically applied through close collaboration with Ragn-Sells' subsidiary, <a href=\"https:\/\/osaservice.ee\/et\/\" target=\"_blank\" rel=\"noopener\">R-S OSA Service O\u00dc<\/a>, which aims to develop innovative solutions from deposited oil shale ash.\r\n\r\n\"Our main collaboration with Ragn-Sells began through the Smart Specialization project of the Estonian Business and Innovation Agency (EIS), and we have been partners in various development projects ever since,\" Uibu explained.

To achieve this, they are developing an innovative technology that allows for the extraction of precipitated calcium carbonate (PCC) from oil shale ash. This calcium-rich material can be processed through a two-step ammonium salt-based extraction method to produce high-purity PCC.\r\n\r\nThe applications of precipitated calcium carbonate are vast\u2014it is used in construction materials, industrial products, and even in the food industry as a filler and colouring agent. Its suitability depends on factors like particle size, morphology, and purity.\r\n\r\nA key challenge is working with deposited oil shale ash. \u201cWe initially started research with fresh oil shale ash, but we soon had to shift focus to deposited ash heaps, as oil shale-based electricity production is likely a thing of the past\u2014meaning fresh ash will no longer be available in the future,\u201d explained Mai Uibu.\r\n\r\nThis shift required new solutions, as deposited ash is significantly more challenging to process. Its calcium compound content varies layer by layer, requiring additional pre-treatment. \u201cFresh ash from power plants already has a suitable particle size, but deposited ash must first be mined, sorted, and ground before it can be used,\u201d she added.","image":null,"align":""},{"acf_fc_layout":"image","image":10022},{"acf_fc_layout":"text","type":"text","text":"<h4>A unique approach in Europe<\/h4>\r\nMai Uibu emphasizes that the R-S OSA Service O\u00dc oil shale ash project is one-of-a-kind in Europe. While various methods for producing precipitated calcium carbonate (PCC) from waste materials have been researched worldwide, no one has yet built a pilot plant. \u201cWe are true pioneers in this field.\u201d\r\n\r\nSo far, the collaboration has been highly successful. Laboratory tests and initial pilot projects have shown promising results, and preparations for building the pilot plant are underway. According to Uibu, the foundation stone has already been laid, and the first pieces of equipment have been ordered. Test operations will begin in the spring of 2026 if all goes as planned.\r\n\r\nOne of the long-term goals is to expand the technology beyond oil shale ash to other industrial waste materials. \u201cEstonian oil shale ash is quite specific, but a similar approach could be tested with steel slag or paper industry waste.\u201d\r\n\r\nStudies estimate that Estonia has around 600 million tons of deposited oil shale ash, meaning there will be material to process for decades, even after oil shale use ends. \u201cOur goal is not just to eliminate these mountains but to reduce the need for new resource extraction by utilizing what already exists,\u201d said Uibu.\r\n\r\nBeyond calcium carbonate, the research team is also exploring ways to extract valuable elements from the ash. Some of these elements are classified as critical raw materials, making TalTech and Ragn-Sells\u2019 collaboration highly valuable for Estonia and Europe\u2019s economic development. By smartly repurposing oil shale ash heaps as material banks, Estonia's Ida-Viru County could become a new circular economy hub\u2014boosting the region\u2019s industrial sector, creating local jobs, and generating economic benefits for all of Estonia.\r\n<blockquote>\r\n<p style=\"text-align: center;\">\"Our goal is not just to eliminate these mountains but to reduce the need for new resource extraction by utilizing what already exists.\"<\/p>\r\n<\/blockquote>","image":null,"align":""},{"acf_fc_layout":"text","type":"text","text":"<h4>Bold ideas drive progress<\/h4>\r\nMai Uibu emphasizes that reducing environmental impact is a key priority for the project. \u201cOil shale ash still accounts for a significant share of Estonia\u2019s waste production.

Additionally, we need to ensure that the final product meets all industry quality standards.\u201d\r\n\r\nAccording to Uibu, gaps in legislation are another hurdle for circular economy projects. \u201cFor example, we lack clear regulations for CO\u2082 storage and reuse. Open communication and stakeholder collaboration are essential because sustainable development is ultimately a shared goal.\u201d\r\n\r\nIf the project succeeds, it could pave the way for new high-value collaborations and strengthen Estonia\u2019s reputation as a hub for innovation and environmentally friendly solutions.","image":null,"align":""}],"related_authors":[{"author":10492,"position":"Editor"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.4 (Yoast SEO v27.4) -
