Scientists are trying to reduce sulfur compounds and heavy metals content in oil shale and semi-coke using bacteria
TalTech Virumaa College Competence Center and company BiotaTec OÜ embark on the applied research of oil shale and semi-coke microbiological processing.
At the end of 2018 an applied research project "Microbiological treatment of oil shale and semi-coke" got a positive financing decision from the State Support Services Centre. "The goal of the given research is to find methods of reducing the content of noxious impurities, in particular sulfur compounds and heavy metals, in oil shale and semi-coke using natural life activities of micro-organisms consortias. So, with the help of different bacteria, we are trying to turn the hazardous compounds into marketable products and increase the value of oil shale oil via cost-efficient and environmentally friendly way," explained member of the board of BiotaTec Sirli Sipp Kulli (in the photo, author: Anne Menert). Research outcomes will become apparent in autumn this year. R&D SME BiotaTec OÜ has been developing new approaches in so-called "biomining" technologies for different low-grade ores and wastes since 2010.
