Anglesey Aluminium 400 jobs plan
The prospective buyers of the Anglesey Aluminium site have plans for a biomass power station and fish farm which they say could create up to 400 jobs.
Lateral Power also plans to use soiled water from the fish farm and CO2 from the power plant to feed greenhouses where food will be grown.
The announcement comes on the same day that the Flintshire port of Mostyn was chosen as a base to support and maintain the Gwynt y Môr offshore wind farm, creating 100 jobs.
