Case story database

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!

Oxidising agents for the neutralisation of dangerous gases

Mercaptans (thioalcohols) and sulphur compounds are by-products in some pharmaceutical production processes. These compounds are toxic and smell very bad. For neutralisation the company previously used hydrogen peroxide, which is a very reactive chemical. Now they are using sodium hypochlorite instead.

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.

Substitution von Formaldehyd durch Wasserstoffperoxid zur Dekontamination von biologischen Laboratorien und Tierhaltungsanlagen

Die Dekontamination von Laboratorien und Tierhaltungsanlagen der Schutzstufe 2-4, sowie von HEPA-Filteranlagen (siehe TRBA 100/120) wurde lange Zeit mit Formaldehyd durchgeführt. Formaldehyd kann in einem alternativen Verfahren durch das weniger gefährliche Wasserstoffperoxid unter einfacheren Verwendungsbedingungen substituiert werden.
