The new mill, which is part of a £41 million extension of Bridgnorth Aluminium’s factory, was given the go-ahead by Shropshire Council’s south planning committee.

Plans for the rolling mill at the plant in Stourbridge Road include a slightly larger building at the centre of the complex, an oil filter plant and transformer enclosure, two new exhaust stacks that will not rise above the current height of the buildings, plus a new air purification building with its own stack.

Bridgnorth Aluminium took over the former Novelis mills in 2010 and now employs about 310 people, set to rise to 375 by 2017 now the new plans have been approved.

The £41 million investment, warmly welcomed by MP Philip Dunne for bringing more highly-skilled jobs to the town, will see production increasing by a third, from 90,000 tonnes of aluminium per year to 120,000.

It is hoped the first production off the line will start by the end of the year and then new people will start being employed.
