About the project

Projekti lähteülesanne on muuta viimase 60-ne aasta jooksul elektrienergia tootmisest tekkivad tonnid tuhajäätmeid läbi keskkonnasäästliku tehnoloogia taas väärtuslikuks tooraineks paljudele tööstustele. Lisaks aastas ligi tonni tuhajäätmete väärindamisele võidetakse sellega mitmetele tööstusharudele taaskasutatud toorainet, mida muidu kaevandataks või energiamahukalt  toodetaks. 

In addition to the valorisation of large quantities of waste, the technology also makes it possible to use additional raw materials sparingly as well as over and over again. This allows us to reduce several highly significant environmental impacts and release the valuable elements found in waste back into circulation.

This is the third ash valorisation project of Ragn-Sells in Europe. Our important partners in this project are scientists from TalTech and the University of Tartu who work on the development and applied research side of the project. 


At present, energy in Estonia is still mainly produced from oil shale
because the alternatives do not yet generate the required volumes.
The production of oil shale energy generates
over 1 million tonnes of ash waste every year and by valorising this, we can contribute significantly to the reduction of the environmental footprint of
kuni 1 miljoni tonni tuhajäätmeid, mida
which is necessary today.
We want to create a cleaner
living and natural
environment in Ida-Viru County and throughout Estonia.


The scientists of TalTech and the University of Tartu
and the team of Ragn-Sells AS
are developing an industrial technology
for the climate neutral separation and recovery of the elements found in oil shale ash,
following the example of similar circular economy projects
implemented in Sweden.


The majority of the elements in the periodic table
are becoming difficult to obtain.
This technology
gives new value to ash waste by extracting
elements that can be used in various sectors,
such as the paper,
paint, plastic
and pharmaceutical industries.


Waste is the foundation of this process for the first time, and the aim of the development of the technology
jäätmed ning tehnoloogia väljatöötamisel on eesmärgiks jõuda finishisse võimalikult jäätmevabalt.
The required wateris used again and again, and energy consumption is reduced to the minimum.
