Cradle to Cradle®

The Cradle to Cradle® principle was devised by Prof. Dr. Michael Braungart and further developed by the EPEA (Environmental Protection Encouragement Agency) in Hamburg. Werner & Mertz has had selected products certified in accordance with this integrated procedure. The Cradle to Cradle® Design encompasses a detailed evaluation key to assess the materials used, their recyclability, use of energy and water and the social impact of product cycles and methods of production.


Products with this symbol are developed for technical and biological cycles.

Werner & Mertz has successfully completed this demanding certification procedure. At the end of 2013 the tana Chemie GmbH, a wholly-owned subsidiary of the Werner & Mertz Group, celebrated a world premiere. For the first time since the creation of Cradle to Cradle® certification, an entire professional cleaning and care assortment – the green care PROFESSIONAL series of eight eco-effective cleaning and care products – received the high award known as "Cradle to Cradle CertifiedCM Gold".

Green care PROFESSIONAL already bears the European "eco-label", which was conceived for the requirements of institutional and industrial users in food service, health care, hotel trade and building cleaning.

Consumers too have access to a sustainable product – Frosch Citrus Shower & Bath Cleaner – that has been awarded the Cradle to Cradle CertifiedCM Gold. In June 2013 Frosch had the first product from the cleaning industry in Europe to earn this certificate. Werner & Mertz attributes this first-class result to its steadfast adherence to the company's sustainability concept.

“We are proud of achieving this outstanding result from the very ambitious Cradle to Cradle CertifiedCM process. Our own exacting demands and quality standards have been validated by an independent institution. Our brands like Frosch, the eco pioneer for more than 25 years, are once again recognized as leaders in sustainability.”
Reinhard Schneider, CEO of Werner & Mertz
