Aughinish Alumina says it has fully cooperated with a review carried out by the Department of Enterprise, Tourism and Employment.
The company says it has taken the claims that its alumina is being used in Russian weapons for the invasion of Ukraine "with the utmost seriousness".
It has announced plans, together with its parent company UC Rusal, to introduce an enhanced traceability framework.
A statement issued by company this evening says this framework will involve independent third-party verification to monitor the movement of alumina from Aughinish, and the subsequent export out of Russia of the aluminium produced from Aughinish’s alumina in Russian smelters.
The company says the system is intended to provide verifiable evidence to the Irish government and the European Commission that its alumina, and any aluminium produced from it, have no connection to the Russian military supply chain.
Aughinish says it will continue to work with government departments in its role as a supplier of a critical raw material to Europe and as a major regional employer.
According to Aughinish, the review concluded there is no evidence that alumina produced at its Irish refinery is used in Russia's military supply chain.
The Department of Enterprise says no adverse findings have been determined in relation to the export of products by Aughinish Alumina to Russia.
Aughinish says it remains willing to take part in any framework that provides greater transparency and traceability.
It has also thanked its employees, suppliers, neighbours and the wider West Limerick community for their support during the recent media attention.
