Operator Stena Line which also owns the Port of Holyhead has bought the former Anglesey Aluminium site.
Smelting came to an end at the site in 2009 - with Orthios later taking it on and developing a materials recycling facility.
But earlier this year the business collapsed with up to 100 staff losing their jobs. Begbies Traynor were appointed as administrator by the main investor and the land put up for sale.
Now Swedish ferry firm Stena - which has owned and operated Holyhead port for 27 years - has announced it has bought the 213-acre site. They said it was bought to facilitate the extension of the port’s operations in the area.
The firm said the new site has the potential to provide additional land and services to existing customers and attract new long-term uses and investment to Holyhead.
Ian Hampton, executive director, Stena Line UK Ltd, said: “This purchase is a significant investment for us and forms an important part of our long-term strategy for the future of Holyhead Port. Our plans for the site have the potential to be a significant boost for the regional economy and local jobs. Holyhead is the largest port we own and remains the second busiest RoRo port in the UK, as well as the main route to Ireland.
