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.

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.

Substitution of aluminosilicate ceramic fibres in vitrification furnaces

A manufacturer of accumulators for sanitation of water used vitrification furnaces covered with fireproof ceramic fibres of aluminosilicate. These fibres are carcinogen and workers, by advice of the regional union health and safety department, demanded their substitution. Wollastonite® was chosen as an alternative product. Wollastonite is a highly resistant calcium silicate used in coating compounds as an alternative to asbestos and artificial fibres.

Substitution von Aluminosilikat-Keramikfasern in Sinteröfen

Ein Hersteller von Sammelbehältern für Abwasser verwendete Sinteröfen, die mit feuerfesten Keramikfasern aus Aluminosilikat bedeckt waren. Die Fasern sind karzinogen, und die Arbeitnehmer verlangten auf den Rat der Gesundheits- und Sicherheitsabteilung der regionalen Gewerkschaft hin ihre Substitution. Wollastonit® wurde als Alternativprodukt ausgewählt. Wollastonit ist ein hochbeständiges Calciumsilikat, das in der Ummantelung von Stoffen als eine Alternative zu Asbest oder künstlichen Fasern verwendet wird.

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.

Life cycle assessment of three paints

An assessment of environmental and occupational health impacts of a powdered paint, a solvent based paint and a water-based paint showed that xylene, titanium dioxide and TGIC are first priority to substitute. Beta hydroxy alkylamide is suggested as an alternative for TGIC . No successful chemical alternative for xylene was found, but other water based paint systems could be used. No alternative to titanium dioxide was suggested.

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.

Alternatives for wood varnishes containing solvents

Alternative wood varnishes products based on water can be identified by applying GISBAU (German hazardous substances information system for the construction sector). Naphtha (petroleum), hydro desulfurized heavy and 2-Butanone oxime classified as carcinogens can be replaced by safer alternative.

Alternatives for polyurethane coating for drivable and slip resistant surfaces

Alternative polyurethane coatings can be identified by applying GISBAU (German hazardous substances information system for the construction sector). This example covers the replacement of product containing two carcinogens, sensitizer and reprotoxic, by safer and more environmental-friendly alternative.

Comparison of surface treatment agents for wood, focusing on chemical hazards

Alternative parquet lacquer based on acrylic dispersions can be identified by applying GISBAU (German hazardous substances information system for the construction sector). In this example naphtha (petroleum), hydrotreated heavy classified as a carcinogen and 1-Methoxypropan-2-ol can be replaced by safer alternative.
