Search for Successfully Implemented Alternatives

You can use the free text search function to find information in the case story database. Most suitable are: substance name and other substance identifier (EC- and CAS-number). You can refine your search after first entry for sector-, function- and process-categories. The case studies are meant to serve as source of inspiration and ideas for substitution. The alternatives are constantly being developed further. We therefore recommend that you to check in each individual case whether an alternative is suitable for your applications and purposes. If you are aware of any other relevant information that is not mentioned in the current case story, please contact SUBSPORTplus.

In order to utilize information in the best way, please take note of the SUBSPORTplus methodology on case stories!

Substitution von Perchlorethylen durch Nassreinigungsverfahren in chemischen Reinigungen

Perchlorethylen wird als Lösungsmittel in der chemischen Reinigung verwendet. Perchlorethylen ist eine sehr gefährliche Substanz mit nervenschädigenden und endokrinen Wirkungen. Arbeitnehmerinnen, die von diesen Problemen betroffenen waren, beschlossen die Eröffnung einer Nassreinigung. Für die Reinigung von Kleidungsstücken nutzt die Nassreinigung Wasser, Wasserdampf und Seife und erreicht ähnliche Ergebnisse wie die chemische Reinigung, nur ohne Gesundheits- und Umweltgefahren.

Boric acid-based soldering flux and selenium sulphide-based silver oxidiser phased out in jeweller's workshop.

A jeweller operating a personal workshop implemented a chemical substitution to improve occupational safety at work. After checking the hazard information of all used chemicals, two mixtures were prioritised for substitution: i) soldering flux containing boric acid (CAS: 10043-35-3; EC: 233-139-2) and disodium tetraborate/Borax (CAS: 1303-96-4; EC: 215-540-4). Both are included in the candidate list; and ii) silver processing (tarnishing) mixture containing sodium selenite (CAS: 10102-18-8; EC: 233-267-9). The use of hazardous chemicals in a jeweller?s workshop is a little addressed issue, especially in small sized companies and personal workshops. But personal exposure issues can be a driver to switch to environmentally and health-friendly chemicals and processes.
