Italy: Cemitaly has been allowed to use slag and ash in cement production at its Taranto plant following an investigation, according to the Il Fatto Quotidiano newspaper.

Ukraine: United Minerals Group (UMG) has signed a contract with Belgium company Sibelco to supply 45,000t of boiler slag from the ash dumps of DTEK’s thermal power plants to Sibelco’s division in the Netherlands. UMG has also commissioned slag-washing equipment to improve the quality of the product.

“Annually, Ukrainian thermal power plants generate up to 8Mt of ash and slag, with 90% of them it stored in ash dumps. Therefore we are interested in expanding markets for such waste. Our cooperation with such companies as Sibelco makes it possible to apply ash and slag to commercial ends,” said UMG Sales Director Sergey Melnichenko.

UMG started processing and selling ash and slag in 2013. In 2014 it launched a mill for production and processing of fly ash in Druzhkovka. In 2015, it sold 348,200t of ash and slag materials worth US$5m, including 31,500t exported abroad.
