As part of a conversion of a former industrial park near the Catawba River in North Carolina, Clariant has participated in the restoration of a portion of the endangered river landscape, specifically 175 ac (700 000 m2) along a 6 km stretch of river. The river could be renaturalized to a large extent along this section thanks to the investments made by Clariant and the support of other companies. This was accomplished by excavating contaminated soil, restoring the original river course and by reinhabiting animals. Additionally, a so-called »eco-industrial park« was developed on the premises of the former industrial production site. This is an establishment for sustainable and innovative companies in the areas of renewable energy and recycling. Clariant received a recognition certificate from the US Environmental Protection Agency (EPA) for this contribution in 2014.
