Caustic Recovery Plants changing mercerising waste water into money.

Körting Hannover AG is a global market leader of Caustic Recovery Plants (CRP). Its technology
efficiently cleans lye that is highly concentrated and has been soiled when yarn-dyeing products and
denim items are used. The process is already quite impressive, because the return on investment is
less than one year.
For years, the textile industry has relied on Körting CRP to guarantee sustainable production. With
the help of Körting Caustic Recovery Plants, the waste weak lye produced during the mercerisation
process can be transformed into concentrated caustic soda and used again. Lye cleaning systems
with peroxide have had a good track record for years and years. By developing the process over a
long period of time and constantly listening to customers’ requirements, Körting can offer a
sophisticated and innovative solution that is popular the world over.
