About the project

The objective of the project is to convert the tonnes of ash waste produced by energy generation every year into valuable raw materials for many industries using an environmentally friendly technology. In addition to the valorisation of almost a tonne of ash waste per year, this provides recovered raw materials to several industries, which would otherwise be extracted or energy-intensely produced. 

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. 

IDA-VIRU COUNTY
WITHOUT ASH HILLS

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
oil shale energy as a solution
which is necessary today.
We want to create a cleaner
living and natural
environment in Ida-Viru County and throughout Estonia.

INNOVATION
FROM ESTONIAN SCIENTISTS

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

RARE
ELEMENTS

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-FREE
PROCESS

Waste is the foundation of this process for the first time, and the aim of the development of the technology
is to cross the finish line with as little waste as possible.
As a result, all flows must be necessary for one sector or another.
The required wateris used again and again, and energy consumption is reduced to the minimum.
