Certificates are proof of our progress
National and international certificates verify the quality of a company’s processes and products. Our goal is to earn and retain them. We see each certificate as clear evidence of the long-term sustainability commitment of employees and the company’s management.
From the audits required for certification, we learn how we can further optimize our operations. Every certificate brings us new incentive and serves as a motivational milestone in our continuous improvement process.
Cradle to Cradle®
We develop all our products according to the Cradle to Cradle® principle. It replaces the linear production principle of Cradle to Grave in which materials are often wasted, with no conscious consideration given to the long-term conservation of natural resources. In contrast, our products are designed for a closed biological or technical material cycle. Then product materials can be returned safely and completely to the biosphere or can be recovered for high-quality reuse.
The European Eco
–label (environmental daisy logo) is the driving force behind environmentally friendly formulas in cleaning products. The daisy logo was created in the mid-1990s to serve as a European environmental symbol. The Ecolabel, which incorporates all national environmental symbols, specifies the stringent requirements for environmentally friendly products. Many of our cleaners for the European market are made with Ecolabel certified formulas.
The Nordic Swan is the Nordic ecolabel. It certifies products, including chemical cleaners, for their environmental compatibility. Green Care Professional products that bear the Nordic ecolabel comply with its strict eco-toxicological requirements. The Nordic Swan was intended originally for use in Scandinavia, but is now found on products marketed outside the Nordic region. The Nordic Swan is awarded in some categories in which the EU ecolabel is not granted for chemical cleaning products, e.g., dishwasher detergents.
Since 1990 the Österreichisches Umweltzeichen has conducted strict examinations and has certified products and services that comply with its demanding standards for quality, environmental and health protection. The ecolabel issued by the federal government guarantees formulas free of hazardous substances and product design that’s durable, suitable for intended use and compliant with standards. As a quality seal for the ecological economy, it identifies products from manufacturers like Werner & Mertz that have committed to producing environmentally friendly products.
Based on an audit report submitted to its Quality Committee, “Gütegemeinschaft Rezyklate aus haushaltsnahen Wertstoffsammlungen e. V.” this certification serves as proof of our high recyclate content in different types of packaging, from spray bottles to canisters.
Since 2003 Tana-Chemie GmbH at its Mainz site and since 2005 Werner & Mertz Professional Vertriebs GmbH in Hallein, Austria, have voluntarily had their environmental management system validated against EMAS criteria. The EMAS validation stands as proof of our exemplary ecological orientation and our integrally sustainable corporate philosophy. Every year an independent auditor examines our sites’ fulfillment of requirements from the EMAS regulations. EMAS, the Eco-Management and Audit Scheme of the European Union, is recognized as the world’s most demanding system for sustainable environmental management. Both successes and areas requiring further action are communicated transparently.

In June 2021 Tana-Chemie GmbH received a Platinum medal for sustainable business from the renowned CSR/Sustainability rating agency EcoVadis. That designation places Tana-Chemie among the most sustainable companies in the world because the best score is awarded in only one percent of all cases.

More than 75,000 companies in 200 industries around the world engage EcoVadis to assess their value chains objectively.

For our headquarters building in Rheinallee in Mainz, we received in 2012 LEED Platinum, the most demanding certification for sustainable construction. The new building was Germany’s first industrial headquarters placed in this top award class. LEED stands for Leadership in Environmental & Energy Design, a classification system for top ecological buildings.
The green energy concept is particularly impressive. By means of wind turbines, photovoltaic panels and geothermal groundwater use, the building generates 20 percent more energy than it needs for normal operation.
