Aughinish Alumina has been given €2.1 million of public money to treat its ‘red mud’ dump on the banks of the River Shannon.
The bauxite refinery has operated in Limerick since 1983 and is now the largest of its kind in Europe producing 1.9 million tonnes of alumina a year.
Its parent company, Rusal, is part owned through En+ by Russian oligarch Oleg Deripaska who escaped EU sanctions following the war on Ukraine.
