Wacker Chemie to Expand Polysilicon Capacity in Germany


Wacker Chemie is planning to invest €130m to expand its production of hyperpure polysilicon at two plants in Germany.

The company is planning to debottleneck its plant in Burghausen to increase polysilicon capacity by 5,000t/year, bring total capacity to 37,000t/year.

The polysilicon facility at Nünchritz is under construction and is scheduled to come onstream by the year’s end. It has capacity to produce 10,000t/year; following the expansion this will increase to 15,000t/year.

The company is also planning to build a new polysilicon plant in Cleveland, Tennessee, US, which will have a production capacity of 15,000t/ year. It is expected to be completed by the end of 2013.

Wacker's total hyperpure-polysilicon production capacity is expected to increase to 67,000t/year by 2014.
