Salt End or Saltend is a hamlet in the East Riding of Yorkshire, England, in an area known as Holderness.

[12] The BP acetyl plants at Salt End produce about 900,000 tonnes (890,000 long tons; 990,000 short tons) of acetic acid and acetic anhydride per year,[13] making BP the largest producer of these chemicals in Europe.

INEOS had invested £40 million in the plant but it couldn't make a profit against cheaper imports from the United States and Saudi Arabia.

[16] Vivergo Fuels was a joint venture between BP, Associated British Foods and DuPont, with a 500,000 tonnes (550,000 tons) per year wheat-to-bioethanol plant at Saltend (although BP later sold its stake to Associated British Foods which gave them a 94% stake in the company).

[19] Vivergo's construction was the subject of industrial action in March–April 2011 resulting from the termination of a contract with Redhall Engineering.

[23] But in February 2021 it was announced that the plant would be restarted after the UK Government stated that E10 fuel would be introduced from September 2021.

The waste product of electricity generation is steam at the rate of about 120 tonnes/h which is sold to BP Chemicals to use in their process.

Although Yorkshire Water invested £30 million in October 2015 to improve the odours emanating from the plant,[29] local people in Preston and Hedon have employed solicitors to bring about legal action over the smell.

When the product enters into the waste stream, it causes no toxic gases when burnt and only burns at half the temperature of polyethylene.

[31] In July 2021, clearance works were started on a new factory designed to process rare earth metals mined in Africa.
