Substitution description

Tchibo GmbH decided to eliminate PFC-finishings for water and stain repellent clothing in 2012. Since 2013 the company has been using only PFC-free finishing for outdoor textiles. For rain and outdoor wear the finishing “ecorepel®” from Schoeller Technologies AG is used. Production, usage and placing in the market of PFOS are forbidden (1 μg/m² in textiles and coated materials) in Europe according to 850/2004/EG („POP“- regulation), changed by EU-regulation 757/2010. PFOA and PFOS are listed as SVHC substances.

PFCs are tested on a regular basis in the final products. To raise the awareness also for cross contaminations from and during production, suppliers have been informed. The usage ban for PFCs has been extended in 2015 to ensure that the company articles are not contaminated.
The company continued to request more information with regards to the chemical finishes which are applied to the company products and developed a finishing questionnaire. The questionnaire is completed by the finishing suppliers, if Tchibo does not yet have any experience with the finishing product. Based on the results of the questionnaire, the company creates a selection of approved finishing sorted in the different application categories.
To maintain consistent quality standards of the active wear from the company, which is the most important product category for water repellent finishing, only ecorepel® is used. Only the oil repellency, which is relevant e.g. for ties or table cloth, is not given. Until today the company receives no negative feedback from the customers about changing from PFC to PFC-free finishing.

http://www.subsport.eu/case-stories/418-en

The company will enhance both training and auditing of suppliers in order to continuously improve the chemical management and phase out of hazardous chemicals in the supply chains.
For any chemical substitution the following conditions must be met:
– Significant information on hazardous intrinsic characteristics for the substance is available
– It is ensured and verified that the substitution is nonhazardous
– Application of the alternative formulation in the same process has been tested and the use of substitution can be technically implemented
The company will publish a revised case study after having gained more results about approved methods and alternative chemicals.
