In a letter, the National Biodiesel Board and the American Soybean Association are asking President Trump to provide additional help in supporting policies to expand production and use of biodiesel.

Also, the president needs to back the biodiesel industry’s request to Congress to provide long-term certainty for the biodiesel and renewable diesel tax incentive.
