Winnington is the home to Brunner Mond UK chemical works, where soda ash is created. Polythene, the material used in many plastic items, was first made at the chemical works by Reginald O. Gibson and Eric W. Fawcett in 1933, during an experiment that 'went wrong'. Most residents in Winnington were employed by ICI ; however, many people now work in the town centre, with Brunner Mond still employing hundreds of people. Most of the houses built closer to the ICI plant were built by the company to house their workers.
