Company History

ECOSYL Products Limited was originally part of Imperial Chemical Industries (ICI). Based in the Agricultural Division, the business rapidly developed novel agricultural biotechnology. In 1993, ICI split into Zeneca Limited with the rump of the heavy chemicals business staying in a revamped ICI. The Agricultural Inoculants division continued its development under the wing of Zeneca. As time progressed and Zeneca became a pharmaceutical company it was clear that Agricultural Inoculants did not fit. Dr Beardsmore and Dr Owen acquired the business in a management buyout in July 1996.


An International Business

Since the buyout the Company has become a major International Manufacturer and supplier of forage treatments. The ECOSYL Products Group now consists of the following companies and has sales in more than 20 countries.

  • ECOSYL Products Limited in the UK
  • ECOSYL Products Inc, based in Byron, Illinois, USA
