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!

Substitution von Toluol, Xylol und Naphtha als Lösungsmittel zur Reinigung von Werkzeugen in einer Autowerkstatt

Dieses Fallbeispiel beschreibt die Substitution von „Safety Clean“ (ein universelles Lösungsmittel, bestehend aus Toluol, Xylol, Naphtha und anderen Inhaltsstoffen). Das Entfettungsmittel wurde in einer Autowerkstatt zur Reinigung von Arbeitswerkzeugen eingesetzt.

Substitution of toluene, xylene and naphtha as solvents for cleaning tools in garages

This case study describes the substitution of Safety Clean (a universal solvent consisting of toluene, xylene, naphtha and other ingredients). The degreasing agent was used in a garage for cleaning work tools.

Substitution of a naphtha-based solvent in the cleaning of printing rolls

A naphtha-based solvent was used to clean printing rolls. It contained naphtha (carcinogens), 2-butoxyetanol (endocrine disruptor and neurotoxicant) and volatile organic compounds. The product was handled manually on a regular basis which implied a dangerous practice. It was substituted by another solvent with no significant impact on human health.

Changing from old technique for development of film to the "computer to plate" (CTP) technique in a small printing house

Printing plates, which were fixed and developed based on a photographic film, were substituted with a technique called computer to plate - CTP. With this technique, the files are directly transferred from computer files to the aluminium printing plate in a closed system. The developer and fixer have been replaced by a finisher.

Substitution of subtilisins in manual cleaning of flexible endoscopes in hospitals

In a hospital in the Capital Region of Denmark cleaning of flexible endoscopes with enzymes was substituted by a product based on triethanolamine hereby reducing the risk of allergy. The substitution can only be performed if the succeeding machine wash is not based on aldehydes.

Different ways to phase out halocarbons like dichloromethane in various applications.

This document describes how a large portion of the halocarbons used and manufactured in Sweden were phased out during the late 1980´s and early 1990´s. Several specific examples are mentioned concerning what chemicals were substituted and what the alternatives were. The chemicals discussed are mainly: dichloromethane, trichloroethylene, 1,1,2-Dichloro-1,2,2-trifluoroethane and 1,1,1-trichloroethane.

Substitution bromierter Flammschutzmittel durch nicht halogenierte Alternativen unter Verwendung der GreenScreen™ for safer chemicals Methode zur Bewertung von Alternativen

HP arbeitet daran, bromierte Flammschutzmittel (BFRs) in neuen Produkten stufenweise zu ersetzen, die bisher noch bromierte Flammschutzmittel enthalten. Um zu bewerten, ob die im Handel erhältlichen Alternativen zu BFRs weniger negative Einflüsse auf Gesundheit und Umwelt haben, wurde eine integrierte Bewertungsmethode für die Analyse der möglichen Ersatzprodukte entwickelt. Dieser integrierte Ansatz beinhaltet ein vergleichendes Screening chemischer Gefahren, das auf einem Tool namens Green Screen™ for safer Chemicals [http://www.cleanproduction.org/greenscreen.php] basiert, einem von der Nicht-Regierungsorganisation Clean Production Action entwickeltes System. Dieses Fallbeispiel stellt den integrierten Ansatz bei der Suche nach geeigneten Alternativen zu BFRs vor.

Substitution of brominated flame retardants with non-halogenated alternatives using the GreenScreen™ for safer chemicals alternatives assessment tool.

HP is working to phase out brominated flame retardants (BFRs) in new products that currently contain BFRs. To evaluate whether commercially available alternatives to BFRs have a lower adverse impact to human health and the environment, an integrated assessment approach was developed for analysing potential replacements. This integrated approach incorporates a comparative chemical hazard screening step based on a tool called the GreenScreenTM for Safer Chemicals [http://www.cleanproduction.org/greenscreen.php], a framework developed by the non-governmental organisation Clean Production Action. This case study examines the integrated assessment approach in the search or suitable alternatives to BFRs.

Enzymes in pharmaceutical productions can be used for degeneration of meat and for cleaning after greasy productions as an alternative for sodium hydroxide.

Enzymes can be used for cleaning after greasy productions. Lipase and alcalase can replace sodium hydroxide solutions for cleaning. The enzymes are gentler to the production equipment compared to sodium hydroxide, a strong base.

Vegetable oil esters used in cleaning of small parts from metal repair work

A shipbuilding company located in Germany substituted hydrocarbon solvents with esters based on coconut oils. The esters are used for cleaning of small items like bearings, casings or bolts from repair work and maintenance in a ship yard.
