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.

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.

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.

Corrosion protection within industrial surface treatment

For industrial surface treatment the products are usually chosen on a basis of their technical properties. These products, however, can have serious consequences for the working environment and the external environment. The brochure that provides the basis for this case story contains a ranking system used for industrial surface treatment which takes the working environment and the external environment into account.

Hydromechanische Entkalkung unter Verwendung von Kesselstein als Abrasivmedium als Alternative zum Beizen mit Säure

Das Beizen mit starken Säuren wie Salz- oder Schwefelsäure zur Entfernung von Kesselstein nach dem Warmwalzen kann durch eine nicht-chemische Methode ersetzt werden. Ein deutsches kleines oder mittleres Unternehmen (KMU) entwickelte eine Alternative, die Wasserstrahlen und als Abfall anfallenden Kesselstein als Abrasivmedium verwendet. Die Vermeidung von Chemikalien und die Senkung der Kosten sind die Vorteile der Alternative.

Hydro-mechanical descaling using scales as abrasive medium as alternative to acid pickling

Pickling with strong acids like hydrochloric and sulphuric, for removing the scale after hot rolling, can be replaced by a non-chemical method. A German SME developed an alternative using water jet and waste scale as abrasive material. Avoiding chemicals and cost reduction are the advantages of the alternative.

Solvent free technology for metal and polymer coatings

Solvents used in coatings may contain substances that are hazardous to health and the environment. An alternative solvent free technology uses plasma and powder materials to obtain high quality coatings with variable thickness, on various surfaces. The technology is also applicable for 3D objects.
