EMAS

Eco-Management and Audit Scheme

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. Successes are communicated as transparently as areas requiring further action. EMAS-validated companies provide strong impetus toward a sustainable, legally compliant economy.

Cradle to Cradle

The Cradle to Cradle® principle was devised by Prof. Dr. Michael Braungart and William McDonough and further developed by the EPEA (Environmental Protection Encouragement Agency) in Hamburg. Werner & Mertz has selected products and product groups certified in accordance with this holistic 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. Werner & Mertz has successfully completed this demanding certification procedure. At the end of 2013, Tana Chemie GmbH, a wholly-owned subsidiary of the Werner & Mertz GmbH, 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 cleaners – received the highest award known as "Cradle to Cradle Certified Gold".

DIN ISO 14001

Standard for environmental management systems

For many years Tana-Chemie in Mainz and Werner & Mertz Professional Vertriebs GmbH in Hallein have been ISO 14001 certified. The ISO 14001 is the globally accepted and applied standard for environmental management systems. By satisfying the requirements of the international norm, our Environmental Management System ensures that we improve our environmental performance, fulfill legal obligations and achieve our environmental goals. Compliance with standard requirements is examined annually by an independent auditor.

DIN ISO 50001

Standard for energy management systems

Tana-Chemie GmbH in Mainz and Werner & Mertz Professional Vertriebs GmbH in Hallein have been ISO 50001 certified for several years. The ISO 50001 is the globally accepted and applied standard for energy management systems. The international norm stipulates the requirements for our Energy Management system with which we increase our energy efficiency and continuously improve our energy performance. Every year an independent auditor examines our compliance with the standard requirements.

DIN ISO 9001

Standard for quality management systems
Tana-Chemie GmbH in Mainz and Werner & Mertz Professional Vertriebs GmbH in Hallein have been ISO 9001 certified for many years. The globally recognized and applied standard ISO 9001 specifies the requirements for a quality management system. By fulfilling this norm, our Quality Management system meets our customer expectations, monitors and continuously improves structures, workflows and quality-relevant processes. Our compliance with standard requirements is examined annually by an independent auditor.

EU Ecolabel

The EU Ecolabel is valid throughout the European Union and is awarded by national certification bodies. It is issued by the EU for products and services. Among other things, the EU Ecolabel aims to limit hazardous ingredients, protect aquatic organisms, encourage use of degradable ingredients and reduce the use of plastic in packaging. Other EU Ecolabel criteria include sustainable procurement of palm and palm kernel oil derivatives, understandable instructions for use and proof of performance.

Nordic Swan

The Nordic Swan is the official Ecolabel for Nordic countries (Denmark, Finland, Iceland, Norway and Sweden). It is the toughest Type 1 Ecolabel in Europe. The Nordic Swan differs from the EU Ecolabel in that it has very strict limits for Volatile Organic Compounds (VOC), for toxicity to aquatic organisms, and for aerobic and anaerobic degradability. The Nordic Swan also demands sustainable procurement of palm oil, palm kernel oil and their derivatives. In addition, it excludes the use of dyes and skin sensitizing preservatives. Nordic Swan criteria for designing packaging for recycling are stricter too (e.g., labels have to pass a wash-off test). 

Austrian Ecolabel

Since 1990 the Österreichisches Umweltzeichen has conducted strict examinations and 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 long-lasting, usable 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.

EcoVadis Platinum

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. Since 2007 EcoVadis has assessed companies' environmental and social practices. The ratings are made in four assessment classes of Bronze, Silver, Gold and Platinum. More than 75,000 companies in 200 industries around the world engage EcoVadis to assess their value chains objectively. In many industry sectors the rating has become a key prerequisite for receiving approval as a supplier. The demanding audit encompasses 21 indicators in the four major themes of Environment, Labor and Human Rights, Ethics and Sustainable Procurement. The themes of Environment and Sustainable Procurement played an important role in the rating. EcoVadis gave positive assessments for the use of recyclable packaging, the utilization of renewable energy and the reduction in water consumption by means of innovative methods, including re-use of water from operational processes.

Austrian Ecolabel

As the Austrian Ecolabel was specifically conceived for the Austrian market, it is particularly relevant and respected in that country. Unlike the EU Ecolabel, it does not allow any ready-to-use spray applications for all-purpose cleaners. However, the Austrian Ecolabel does certify floor care products.

Cradle to Cradle Bronze

The certification is based on the principles of eco effectiveness, which were developed by the architect   William McDonough and the process engineer and chemist Prof. Dr. Michael Braungart. The goal is to design products in such a way that they can be returned to biological and technical cycles. C2C certification looks at a product holistically, with an evaluation made in five categories: Material health: All materials in the product should be harmless for humans and the environment. Product circularity: After use, the materials should be recycled or composted easily. Clean air and climate protection: The manufacturing process should have positive effects on air quality, the supply of renewable energies and the impact of greenhouse gases on the climate. Water and soil protection: Responsible handling of water and the soil eco systems is important for certification. Social responsibility: The manufacturer must comply with human rights laws and apply fair and just business practices. Besides the formulations, the packaging may be assessed against C2C criteria. The C2C certification is managed by the non-profit organization Cradle to Cradle Products Innovation Institute. Compared to conventional Ecolabels, C2C certification is distinguished by its holistic approach and its emphasis on the circular economy. The certification results are divided into different levels of Gold, Silver and Bronze. Green Care Professional offers the broadest Cradle to Cradle portfolio of professional cleaning products.
