The Associated Octel factory was built to extract bromine from seawater and turn it into an additive for petrol engines.
In 1953 a bromine and DBE production site was built at Amlwch. It was important that the seawater from which the bromine is extracted is as clean as possible, could be replenished with fresh seawater quickly and was warmed by the Gulf S
At the time, petrol used in road vehicles contained lead. Engine “knocking” was a common problem, when the mixture of air and fuel didn’t burn efficiently with each detonation. This could damage engine cylinders over time. The additive produced here reduced knocking and improved engine efficiency.
As the health effects of lead in vehicle exhaust gases became better understood, unleaded petrol was developed. It was introduced to UK filling stations in the 1980s, and leaded petrol was later phased out. As demand for anti-knock additive reduced, the Octel factory diversified into other bromine products and was taken over by Great Lakes Chemical Corporation. In 2003, the corporation decided to close the works with the loss of more than 100 jobs.
