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!

Alternatives to diethyl ether containing adhesives for electrodes used in electroencephalograms

Exposure to a diethyl ether containing adhesive, used to attach the electrodes in long-term encephalograms (EEG), was incriminated for causing dizziness and headache to nurses but also to patients in two health care units in France. The case describes the exposure during different phases of the EEG, and proposes measures to replace the adhesive or to change the way electrodes are fixed, making the adhesive unnecessary.

Ein neuer einspritzbarer Mörtel/chemischer Anker für Bauprojekte.

Einspritzbarer Mörtel wird verwendet, um Betonbauteile zu verbinden, zum Beispiel beim Bau von Gebäuden. Konventionelle Produkte enthalten allergene Stoffe und ihre Handhabung erfordert eine spezielle Ausbildung. Außerdem muss das Material als Gefahrenabfall entsorgt werden. Den Ansprüchen eines Skansa-Kunden folgend, entwickelte der Lieferant ein neues Produkt, indem auf einen der Gefahrstoffe verzichtet und die erforderliche Menge eines anderen erheblich reduziert wurde. Darüber hinaus sind für die Anwendung des neuen Produktes keine speziellen Sicherheitsmaßnahmen notwendig.

New injectable mortar/chemical anchor for construction projects

Injectable mortar is used to join concrete construction elements, for example in the construction of buildings. Conventional products contain allergenic substances and require specialist application training. Furthermore, the material has to be dealt with as hazardous waste. Following environmental demands from one of Skanska’s clients, the supplier developed a new product, which involved the removal of one hazardous substance and the significant reduction of another. In addition, the new product requires no specific safety measures during application.

Formaldehydfreie Bindemittel für die Herstellung von Holzwerkstoffen

Harnstoff-Formaldehyd Klebstoffe sind in der holzverarbeitenden Industrie weit verbreitet. Baumaterialien stellen nach wie vor eine wesentliche Quelle von Formaldehydabgabe in Innenräumen dar. Es ist deshalb notwendig, alternative formaldehydfreie Bindemittel für Holzwerkstoffe zu entwickeln. Das französische Projekt "Panneaux verts" entwickelte einen Extraktionsprozess für Tannine, der auf Flüssig-Extraktion und Lignin basiert. Diese extrahierten Verbindungen wurden erfolgreich in Klebstoffe eingebracht und damit formaldehydfreie Kleber entwickelt. Die mechanischen Eigenschaften von Holzfaserplatten, die mit dem neuen Klebstoff hergestellt wurden, entsprachen der europäischen Norm.

Glues from renewable resources for panel board manufacture

Urea-formol adhesives are largely used in the wood products industries. Construction materials are the main source of formaldehyde emissions in the indoor environment. Therefore, it is necessary to find new natural alternatives to produce wood adhesives. The project allowed developing and validating extraction process for tannins, based on aqueous extraction, and lignin. These extracted compounds were successfully inserted in adhesives to develop a formula without formaldehyde. The mechanical properties of the panel board produced with this new adhesive responded to European standard.
