There are two bioethanol plants in the UK; Ensus in the North East and Vivergo in Humberside. Together they have capacity to use around 2M t of cereal grain, producing around 700M litres of bioethanol, as well as 700,000 t of high protein animal feed.
From 2004 to around 2014 ADAS undertook several research projects looking at how best to grow wheat for bioethanol. Some of the reports are connected below:
