Betolar starts stream study of flyash from Eesti Energia's power plant

Betolar will start a side stream study commissioned by Eesti Energia to explore the use of ash from oil shale combustion as a binding agent in concrete. This would make it possible to replace cement in concrete either partially or completely. Cement is globally one of the most significant sources of CO2 emissions.

“Oil shale ash is already being used as a substitute for cement in soil stabilisation. Our research aims to find commercial applications with higher added value. Our solutions improve the sustainability and profitability of the value chain of both the mining industry generating side streams and the construction industry utilizing them,” said Ville Voipio, Chief Commercial Officer at Betolar.
