Greener chlorine production

My Wacker sustainability stories are still in the line-up but with this news from Bayer MaterialScience last week about their eco-friendly electrochemical chlorine production, I might as well include some tidbits from Wacker's chlorine production as well.

Bayer said it is building a new chlorine plant that uses common salt with annual capacity of 20,000 metric tons/year at its Chempark Krefeld-Uerdingen in Germany. The new facility will use a oxygen depolarized cathode technology, which the company said, will reduce electricity consumption by up to 30% lower than in standard membrane technology, resulting in an indirect reduction of up to 10,000 metric tons of CO2 emissions each year.
