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.

Evaluation of halogen-free flame retardants in polypropylene formulations as alternatives to flame retardants containing halogens.

This document concerns an evaluation of several halogen-free flame retardants. The evaluation also presents some new types of flame retardants, which are fully functional, commercially available and cost-efficient alternatives to traditional halogenated flame retardants. The details, strengths and limitations of all alternatives are listed below.

Chemical treatment of rubber, wood, leather or metal which protects, preserves and renews the surface of the material. An alternative to carbon black.

This document describes a process for protecting, preserving and renewing surfaces, especially rubber and other natural and synthetic polymers including wood, leather, painted surfaces and metal. The material to be treated is soaked with an aqueous solution of substituted or unsubstituted dimethylpolysiloxane. This is done in several stages with other solutions such as diethylene glycol and/or glycerine. This treatment reduces the impact of deleterious effects such as ozone, ultraviolet radiation and environmental causes to the appearance of especially rubber parts used for example in automobiles.

Phase-out of chrome (III) in tanning processes by switching to vegetable based tanning.

Ersatz von Chrom (III) durch pflanzliche Gerbmittel

Die gebräuchlichste Methode, Felle und Häute zu Leder zu gerben, war lange die Chromgerbung. Chrom wird allerdings mit negativen Auswirkungen auf die menschliche Gesundheit und die Umwelt in Verbindung gebracht. Eine gute Alternative zur Chromgerbung ist die pflanzliche Gerbung, also Gerbung durch pflanzliche Gerbmittel wie die Rinde der Silberakazie.

Animal dolls made without synthetic materials, flame-retardants, allergens or PVC

Animal dolls for children may contain a number of hazardous chemicals, such as flame-retardants, PVC, phthalates. Using natural materials such as organic cotton, wool and linen the amount of hazardous chemicals can be reduced.

Eine Alternative zu Phthalaten: Neuartiger Weichmacher für Kunststoffe hergestellt aus Rizinusöl und Essigsäure

Danisco hat erfolgreich einen biobasierten Kunststoffweichmacher auf der Basis von Rizinusöl und Essigsäure entwickelt. Studien zufolge hat das Produkt keine nachteiligen Auswirkungen auf die menschliche Gesundheit oder die Umwelt und hat Verwendung in der Produktion von Lebensmittelverpackungen, medizinischem Equipment und Kinderspielzeug gefunden. Neuartige Anwendungen werden getestet, eine davonist Vinylfußboden.

An alternative to phthalates: Novel plastic softener produced from castor oil and acetic acid

Danisco has successfully developed a bio-based plastic softener on the basis of castor oil and acetic acid. According to studies the product shows no adverse effect on human health or the environment, and has found applications in production of food wrapping, medical equipment and children’s toys. Novel applications are being tested, one of them being vinyl flooring.

Druckwasser als Alternative für die Reinigung von Sieben im Rotationssiebdruck für den Textilbereich

Das Reinigen von Sieben für den Rotationssiebdruck mit gefährlichen Stoffen wie Dichlormethan und Phenol oder Flusssäure kann durch eine sicherere Alternative ersetzt werden, die Wasser verwendet. Einige Textilbetriebe in Asien haben eine Reinigungsmaschine, die Wasser unter hohem Druck verwendet, eingeführt und sind zufrieden mit den erzielten Ergebnissen sowie mit den gesundheitlichen und ökologischen Aspekten.

Pressurised water as alternative to cleaning of rotary screen in the textile sector

Stripping rotary screens with hazardous chemicals like dichloromethane and phenol or hydrofluoric acid, can be replaced by a safer alternative using water. Textile companies in Asia that introduced a cleaning machine using high pressure water are satisfied with the results and with the safety and environmental performance.

DecaBDE and Alternatives in Electrical and Electronic Equipment (EEE)

The case summarises information from a report from Danish Environmental Protection Agency (EPA) on the use of the brominated flame retardant DecaBDE in electrical and electronic equipment (EEE), and describes suitable alternatives to Deca-BDE. The study has not identified any application of Deca-BDE in EEE for which substitution is not possible, from the scientific or technical point of view. The report lists 25 alternative substances. Some of these are halogenated and will not be listed in this case description.
