The UK's largest bioethanol plant will be forced to close unless the government acts, according to its operator.
In April, Associated British Foods (ABF) said it was in talks with the government to help save its Vivergo Fuels site at Saltend, near Hull, after being forced to cut production levels due to low bioethanol prices.
On Tuesday, Vivergo said the removal of a 19% tariff on US ethanol imports, which was part of the recent UK-US trade deal, was the "final blow".
A government spokesperson said it was working closely with the industry to understand the impacts of the trade deal and it was open to discussions over potential support.
