Cedar Rapids Gazette: Major U.S. ethanol producer Green Plains is shutting down two Iowa plants and cutting output at a Minnesota plant due to low profit margins amid a trade war, Reuters reported Monday, citing five industry sources it did not name. The slash in production comes after the Trump administration’s escalating trade disputes cut off U.S. access to ethanol markets in China, contributing to a domestic supply glut that has pushed biofuel prices near their lowest levels in over a decade. Green Plains idled until further notice its facility in Superior and soon will shut down the plant in Lakota — both in northern Iowa — and cut its plant in Fairmont, Minn., to half capacity, the news service said.
