UK: British Gypsum has completed a Euro7.4m upgrade of its Barrow-Upon-Soar gypsum mine. The investment is expected to secure supplies of gypsum to produce gypsum wallboard for 20 years at the company's production sites at East Leake in Nottinghamshire and Fauld in Staffordshire, and at British Gypsum's sister business Saint-Gobain Formula based at Newark, according to the Loughborough Echo. The upgrade will allow the mine to be expanded using conveyors, fans and other mining equipment.
