(Bloomberg) -- Cocoa processor Blommer Chocolate Co. will close its Chicago chocolate factory as the aging facility is no longer reliable.

The company, owned by Japan’s Fuji Oil Holdings Inc., said its original 1939 plant now costs too much to operate, maintain and repair, and has “created production reliability issues,” according to a statement on Friday.

Blommer, the largest cocoa processor and ingredient chocolate supplier in North America, will focus on its other facilities in Pennsylvania, California and Ontario, Canada. The company plans to invest $100 million in the three factories over the next several years. 

“It was an incredibly challenging yet inevitable decision to close the Chicago plant,” said Mark Okita, Blommer’s chief operating officer and senior vice president of commercial.

Chocolate makers are coming under pressure as cocoa prices have more than doubled this year on lower production from key West African growers.

Meanwhile, Malaysian cocoa processor Guan Chong Bhd. said it is paying premiums for beans from smaller producing countries.
