Vivergo Fuels is a bio-ethanol producer, headquartered in Hessle, East Riding of Yorkshire, but whose plant is based at Salt End, Kingston upon Hull, England. The company produces bio-fuels from locally sourced wheat and besides producing bio-ethanol, a by-product of animal feed is also part of the bio-fuel process. The company's plant was subject to a shutdown between November 2017 and April 2018 whilst demand for their product was low. The company blamed the United Kingdom government for not ruling that bio-fuel additives to petrol should be greater than 4.75%. It is the largest manufacturer of bio-ethanol in the United Kingdom and the second largest producer in Europe. From Wikipedia
