A wind turbine costing £2m has been erected to save energy at a Co Antrim factory.
The structure has been completed at the Mallusk headquarters of Brett Martin, manufacturers of plumbing and drainage systems, plastic roof lighting and glazing materials.
Standing at almost 100 metres, the turbine is one of the largest of its kind on an industrial site in Northern Ireland.
Once fully operational, the turbine is expected to reduce carbon emissions at the Mallusk site by 4,000 tonnes per year and lower energy costs by at least 20% - meaning more competitively priced products for customers.
Laurence Martin, Brett Martin managing director said that the project will bring tangible benefits for the company and its stakeholders.
"As a responsible and forward-thinking company, we are strongly committed to reducing our carbon footprint and to maintaining our competitive position, which is in the interests of the business, our employees and the local community," he said
"We are confident that this wind turbine will enable us to both minimise our impact on the environment and help reduce our high energy costs.
"This in turn will enable us to remain a competitive business, securing further orders across our global market and safeguarding local jobs."
The company began the planning application process in 2008 with assistance from planning consultants Turley Associates.
Work originally began on the project in 2006 with an initial feasibility study supported by the Carbon Trust.
Once planning approval was granted in 2010 the order to supply the wind turbine was placed with German based energy organisation Enercon.
