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!

Coating for industrial washing machines - from binder based on epoxy/polyester to polyester

A Danish company produces industrial washing machines. They substituted a paint based on epoxy/polyester with a paint based on polyester. This new product is not classified and is much better than the former used product, the technical performance is better and the energy consumption lower, which probably counterbalances a higher price.

Surface treatment of metals and plastic

This document describes the best available techniques for surface treatment of metals and plastics. Substitution possibilities for EDTA, PFOS, zinc cyanide, copper cyanide and hexavalent chromium are mentioned.

Sprühnebelunterdrückung bei der Hartverchromung mit Hilfe von nicht auf PFOS (Perfluoroctansulfonat) basierenden Tensiden

Das dänische Amt für Umweltschutz und einige dänische Unternehmen haben ein Projekt zur Substitution von polyfluorierten (PFOS) Tensiden zur Verwendung für nicht dekoratives Hartverchromen durchgeführt. Ergebnisse auf Laborebene und größerer industrieller Ebene haben gezeigt, dass es möglich ist, die PFOS als Mittel zur Sprühnebelunterdrückung in der nicht-dekorativen Hartverchromung zu substituieren.

Mist suppression with non-PFOS (perfluoro octane sulfonate) surfactants for hard chrome plating

The Danish EPA and some Danish companies carried out a project on substitution of polyfluorinated (PFOS) surfactants for use in non-decorative hard chrome plating. Experiments on both laboratory scale and larger industrial scale have shown that it is possible to substitute PFOS as mist suppressant in the non-decorative hard chrome plating process.

Extremes Hochgeschwindigkeits-Laserauftragschweißen (EHLA) als technische Alternative für bestimmte Anwendungen der Hartverchromung

Chromsäure wurde 2013 in die REACH-Zulassungsliste aufgenommen und seine Verwendung erfordert seit 2017 eine Zulassung in der EU. Extremes Hochgeschwindigkeits-Laserauftragschweißen (EHLA) kann eine Technische Alternative zur Hartverchromung darstellen, welche besonders für rotationssymmetrische Bauteile geeignet ist. Das Verfahren bietet eine Alternative für Anwendungen, bei denen erhöhte Anforderungen, z. B. an die Haftfestigkeit der Beschichtung sowie das Verhindern des Korrodierens der beschichteten Fläche und dem Schutz vor dem Verschleiß des behandelten Metalls, gestellt werden.

Extreme High-speed Laser Material Deposition (German: EHLA) as technical alternative for certain applications for hard chrome plating

Chromic acid was added to the REACH authorisation list in 2013 and its use requires authorisation in the EU since 2017. Extreme high-speed laser material deposition (German: EHLA) can provide a technical alternative to hard chromium plating, which is particularly suitable for rotationally symmetrical components. The process offers an alternative for applications where increased requirements are made, e.g. on the adhesion of the coating as well as the prevention of corrosion of the coated surface and protection against wear of the treated metal.
