León - Wacker Chemie AG



WACKER is the first company in the world to produce L-cysteine by fermentation in a patented biotech process. WACKER has acquired a large-scale fermentation plant from Antibióticos de León SLU (ADL) in Spain by the end of 2016, to securely meet the globally growing customer demand for cysteine during the years ahead and to support the commercialization of other bioengineered products.

WACKER is now obtaining a production line with a fermentation capacity of
800 m3. Over the next few years, a total of about €30 million will be invested to modernize the existing facility and to add production equipment, thereby creating some 35 new jobs at the site.

At the León plant in northern Spain, WACKER will produce cysteine by fermentation for the wide use in the pharmaceutical, cosmetics and food sectors. The natural amino acid cysteine is not only used to produce flavorings, but also as a processing auxiliary for breaking down gluten for bakery goods, as a radical scavenger in cosmetics and as an expectorant in cough medicines.

In addition, WACKER will offer fermentation capacity to third parties and will be active as contract manufacturer.
