True eco-effectiveness:
Doing the right things right

Sustainability is often mistakenly equated with efforts made to reduce pollutants. The process, however, has to begin much earlier so that the pollutants never get into circulation. A genuine circular economy goes even further and involves doing the right things right from the start. We live according to this credo along the entire value chain. The raw materials required for production are kept in biological and technical cycles and used again and again. It starts with the use of renewable energy in the production process and our efficient in-house water treatment and extends to integrally sustainable ingredients in formulas and packaging material made of recyclates.
