  • 1914 Erinoid Ltd of Rodborough, was established at Lightpill Mill, near Stroud. The firm manufactured plastic using casein, a substance derived from milk by a patented dry process.
  • The factory quickly became the main source of casein plastic in the UK, producing at least 5 tons a week at the start of the First World War.
