We for Recyclates

Recyclate initiative

With this recyclate initiative launched in 2012, Werner & Mertz, together with its partners, committed to ensuring that plastic waste from European household collections, such as the yellow sack in Germany, is recycled to a high standard so that the recyclates thereby obtained can be reused in our packaging.

Since 2012

The Frosch Initiative

Forward-looking and sustainable solutions for environmental protection and resource conservation are launched. The aim is to provide fresh impetus – above and beyond the cleaning and detergent industry. The Frosch initiative brings together creative minds and organizations to jointly advance innovative ecological approaches from a commercial perspective.

Our commitment to sustainability 

Werner & Mertz, the company behind Frosch, has always addressed the question of how living a more sustainable life can become more widely accepted. With its commitment to sustainability, the family-owned company provides impetus for new sustainable solutions for environmental protection and resource conservation.

Frosch for European cultivation

Natural regional raw materials

In its formulations, Frosch relies on natural-based active ingredients and is researching ways to obtain all of its surfactants (wash-active substances) from European oil plants such as rapeseed, olive, sunflower and flax in the long term. Moreover, it has succeeded in discovering a new plant-based source material: a sustainable acetic acid obtained from certified wood. This comes from a biorefinery in Austria, which is a further boost in the direction of greater regionality.

Nature conservation and environmentally aware action

Under the motto “Frosch protects frogs”, the WWF River Programme and projects dealing with the protection and preservation of the March-Thaya floodplains are supported. This has facilitated the implementation of important renaturation measures. The aim is to free the March from river stones to allow the river to develop naturally again in the long term. In this way, new habitats for amphibians are created.

Environmental management


For over 20 years, Werner & Mertz has maintained a holistic environmental management system aimed at conserving raw materials, reducing the burden on the environment and consuming fewer resources. We have operated this environmental management system since 2003 and our progress in conserving resources has been regularly validated by an independent inspector in accordance with EMAS requirements at our main plant in Mainz and – since 2005 – also at our second production site in Hallein (Austria).

Design for recycling

A functioning circular economy

“Design for Recycling” provides the basis of a functioning circular economy: Old recyclable plastic is turned into a new raw material (recyclate) that can be reused to make equivalent packaging. This allows the plastic to remain within the cycle for a long time, which massively reduces the burden on the environment.

Skin protection with Frosch

Optimum skin compatibility

Since the number of allergy sufferers and people with sensitive skin is constantly increasing, Frosch places great importance on optimal skin compatibility. Therefore, the use of mild preservatives and carefully selected perfumes is minimised or even completely avoided.
The combination of natural, efficient cleaning power and environmental and skin friendliness makes the Frosch brand what it is: naturally good.
