Golden Grain Energy (GGE) in Mason City, Iowa is now home to the world’s largest grain bin, built by Sukup Manufacturing Co. The bin measures 165 feet in diameter with a peak height of 155 feet, 7 inches and boasts a capacity of 2.2 million bushels.

GGE held a Big Bin Bash this week to celebrate completion of the bin with a choir performing a concert in the empty interior. GGE board chairman Dave Sovereign, who also serves as president of the American Coalition for Ethanol (ACE), hosted the celebration for the new addition which will increase the amount of corn the plant is able to store onsite for its ethanol production.

GGE documented construction of the big bin, which began in December, on its YouTube channel.
