The plastic bottles are now made from 100% recycled PET (and no longer just 80%). They are also 100% recyclable. Products in the Frosch range are part of the group's overarching vision that emphasises sustainability. The packaging supplier has been integrated into the product design and manufacturing site, thus reducing the number of lorries on the road by 1,500 every year and translating into savings of 570 tonnes of CO2 and 220,000 tonnes of fuel. The Werner & Mertz factory has been awarded EMAS, ISO 14001 and ISO 9001 certification for its energy management approach.
