Top marks again for Tana-Chemie: The company impresses once more in the EcoVadis rating for 2025

Platinum medal for Tana-Chemie GmbH! The company has done it again, receiving the highest award in this year’s 2025 sustainability rating from the international rating agency EcoVadis. As part of the Professional division of Werner & Mertz, Tana-Chemie is one of the world’s leading companies in terms of sustainability, as the platinum medal is only awarded to the top percentage of all companies.

EcoVadis is one of the leading providers of sustainability assessments and has a global network of more than 150,000 companies from over 250 industries. The provider’s goal is to make reliable and internationally recognized assessments available that help companies minimize risks, drive improvements and achieve positive environmental and social impacts. The assessment evaluates the extent to which companies integrate the principles of sustainability and corporate social responsibility into their business processes, including all policies and measures along the entire supply chain.

“We are delighted to receive this award once again. It is a tremendous honor and confirms once more that our consistent commitment to integral sustainability and our continuous pursuit of optimization in line with the circular economy are having an impact,” says Yannic von Raesfeld, Head of Sustainability Management at Werner & Mertz. “It is particularly gratifying that we were able to improve in all evaluation categories compared to last year.”

EcoVadis evaluates companies based on over 20 criteria in four key areas: environment, labor and human rights, ethics, and sustainable procurement. Tana-Chemie GmbH once again performed especially well in the “environment” category this year. EcoVadis particularly commends the company’s consistent implementation of the circular economy, with a special focus on the use of recycled materials and packaging.

As a sustainability pioneer and socially responsible company, sustainability has been an integral part of Werner & Mertz Professional’s corporate culture for years. Proof of the holistic understanding of sustainability in the Professional Division has come in the form of certifications and awards over the past several years. Honors include certification by EMAS, the world’s most demanding environmental management system, and the sustainable building standard LEED Platinum for the Mainz headquarters. In addition, the family-owned company was recently one of the first industrial companies ever to undergo the We Impact Standard audit. This audit focuses primarily on social and governance aspects in operational processes. As a result, Tana-Chemie GmbH already voluntarily meets many of the requirements of the Corporate Sustainability Reporting Directive (CSRD) and the Supply Chain Due Diligence Act (LkSG). In 2013, the products from the Green Care Professional brand became the first worldwide professional cleaning agents to receive the Gold designation from the renowned Cradle to Cradle Cradle® Certification.

Together with its parent company Werner & Mertz, Tana-Chemie GmbH works within the Recyclate Initiative founded in 2012 to practice and promote effective recycling of plastic from post-consumer collections for the good of the circular economy. A new milestone was recently achieved when the share of recycled PET (rPET) from the Yellow Bag was increased to 75 % for the PET bottles of the Green Care Professional brand. In addition, Werner & Mertz, in cooperation with the global packaging and paper company Mondi, developed a fully recyclable, patented stand-up pouch made of mono-material (polyethylene) with a removable banderole according to the Cradle to Cradle® principles, which was awarded the prestigious WorldStar Packaging Award in 2020.
