in Saltend near Hull, BP operates a petrochemicals plant that produces acetic acid and acetic anhydride used in the production of pharmaceuticals, textiles and other chemical products.
At the same location, the company operates a biofuel technology demonstration plant in partnership with DuPont, which uses feedstocks such as wheat to produce biobutanol.
In 2007 BP formed a joint venture called Vivergo with AB Sugar and DuPont to build a biofuel plant near Hull to convert wheat into ethanol; the remaining plant matter is sold as animal feed. The plant went online in December 2012
