It has been confirmed the Eastman chemical factory in Workington will close, with the loss of 152 jobs.
The winding down process will begin in the next few days, production will end in April, and the closure of the site is expected to be completed in the third quarter of 2015.
The company says it's a business decision, and isn't reflective of the performance of people who work at the site:
The factory manufactures acetate tow, which is used in products like cigarette filters.
Eastman is expecting the closure to save the company more than £13m every year, and says the closure itself will cost around £67m.
