Cement.

In September 1962 Associated Portland Cement Manufacturers Ltd started production at the new cement works. Chalk was quarried on the hills above the town and pumped through a pipe line to the factory below. Clay was dug from the area near the works. 

In 1965 production doubled and the original chimney was demolished and replaced by the taller structure which was demolished in 2018. 

The company was taken over by Lafarge in 2001 and cement production ceased in 2009. The site is currently used as a distribution depot.
