Since the startup of the Clariant plant to produce ethylene oxide, the process-related byproduct, carbon-dioxide (CO2), has been emitted directly into the environment. In 2007, Clariant and a partner specialized in industrial and food processing gases got together to use this CO2 instead of emitting it. The pre-scrubbed, gaseous CO2 is transferred to the partner company via pipeline, where it is liquefied and sold to customers with CO2 requirements. Among others, liquid CO2 is used as carbon dioxide by the beverage industry. Between 2009 and 2010, both companies invested more than EUR 15 million into these new plants. As a result, the direct CO2 emissions from the Gendorf Clariant plants were reduced by 90 percent.
