The Professional Division at Werner & Mertz ...is part of a 150 years group history and was established in 1971. We are the pioneer in integrally sustainable high performing, cleaning and sanitizing products for professional sectors like Facility Care, Foodservice, Health Care, Lodging and Food Processing. Green Care Professional and Tana Professional are the two European leading brands of the Professional Division. As a part of the family-owned Werner & Mertz Group, founded in 1867, we feel very committed to the location in Mainz. Sustainability is not seen as a temporary trend but rather is tradition that the company lives every day. Right from the very beginning, the protection of natural resources, sustainability and preservation of biodiversity have always been our focus. This philosophy is not only incorporated in our products but it is also reflected in our EMAS-validated production sites in Mainz and Hallein and our headquarters in Mainz that has obtained the “LEED Platinum” award. Our highly trained, motivated and action-orientated professionals deliver solutions and services on site that exceed our customers’ expectations. The division headquarter is Tana-Chemie GmbH in Mainz, Germany
