A temporary shutdown of the Braya Renewables refinery takes effect today.

The shutdown was announced last month as the company grapples with lower-than-normal margins and the end of the Blenders Tax Credit in the U.S..

In a letter to employees last month, Vice President of Braya Renewable Fuels Paul Burton indicated that while the tax credit is expected to be replaced until that happens, it is “not economically feasible to continue to process feedstock.”

There is no immediate word on when production will resume – only when “margins improve.”
