Who are the Ensus Group and who is behind it?

The Ensus Group are a bioethanol company set up to manufacture ethanol in different European countries. Their first refinery is the Wilton plant which is currently being built at Seal Sands, near Middlesborough. It is expected to be fully operational by March 2009. The Ensus Group states that this will be Europe’s largest ethanol refinery. Other refineries of approximately the same size, owned by other companies, will start production in 2009, too. In March 2007 Ensus Group was bought by the Carlyle Group and Riverstone Holdings. This was a management by-out, meaning that the management structure and team were retained. The [[Carlyle Group]] and Riverstone Holdings are private equity firms, i.e. investment companies.[[Riverstone Holdings]] specialising in the energy and power sector, whilst the Carlyle Group have a very wide range of investments, including military, car and transport, energy and power, healthcare, real estate, telecommunications, and media..[1] Both firms are increasing their investment in the biofuel sector, particularly in North America but, through Ensus, also in Europe.
