Hickson & Welch

In 1931 Hickson & Welch Ltd was founded, from the site that had been destroyed in 1930.

From 1944 the company made DDT, becoming the UK's largest manufacturer.

Hickson and Welch (Holdings) Ltd was incorporated on 28 September 1951. It made dyestuffs, DDT (pesticide), and timber preservatives. It had the subsidiaries Hickson & Welch Ltd, and Hickson's Timber Impregnation Co. (G.B.) Ltd. The timber subsidiary had been founded on 25 October 1946. The timber preservative contained dinitrophenol, and was marketed as Triolith, Tanalith and Pyrolith. Pyrolith contained a flame-proofing agent.

It became a public company on 30 November 1951. The company became known as Hickson International from 1985.[1]

In August 1991 it sold William Blythe of Lancashire for £23 million to Holliday of Huddersfield.

It bought Angus Fine Chemicals for £22.3 million in July 1992.

In August 2000 Hickson International plc was bought by Arch Chemicals. At the time Hickson employed over 1,300 people, had assets of £73 million, and a revenue of £208 million.

It became known as C6 Solutions and closed in July 2005.[2] The gas fired power station still remains. To the east was Wheldale Colliery, and opposite the site is The Jungle rugby league ground; Castleford is synonymous with rugby league.

In November 1926 an explosion occurred while workers were packing an intermediate dye, thought to be non-explosive. Two men died.

On 4 July 1930, just before noon, there was an explosion on the site's nitration plant. It destroyed the factory, killing 13 people and injuring 32 people. It made 300 houses in the town uninhabitable. Ernest Hickson later died (natural causes, 30 July 1930) and his earlier company was liquidated. Inspector J.A.Gee of the Castleford West Riding Police, was subsequently appointed an OBE by HM George V, for his work following the explosion.

On 21 September 1992, an explosion at the factory killed five workers, and injured around two hundred people. At 13.20 a distillation column still base containing residues of nitrotoluene ignited. The fireball went through the site's control room and killed two men instantly. The fireball then entered a four-storey office block; a woman and two men would later die from their injuries. The explosion cost £3.5 million.

Powergen (now E.ON UK) installed a £30 million CHP gas turbine power station at the site. ENEL Power built the power station, which has a 44MW General Electric LM6000 engine. The generation equipment was built by Nuovo Pignone. It has a 13MW steam turbine, with the site producing around 56MW of electricity.

The power station began operations in October 2002.
