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 und Butan-1-ol in Farben zum Bedrucken von Plastiktüten

In Druckfarben auf Basis organischer Lösungsmittel zum Bedrucken von Plastiktüten wurden gefährliche Chemikalien gefunden; sie wurden durch wasserbasierte Farben ersetzt, die kein Toluol und Butan-1-ol zum Drucken benötigen.

Substitution of toluene and butan-1-ol in inks for the printing of plastic bags

Toxic chemicals found in printing inks based on organic solvents used for the printing of plastic shopping bags were replaced by water-based inks, which eliminated toluene and butan-1-ol from the printing process.

Substitution von Isopropanol, 2-Methylpropan-1-ol und Heptan für die Reinigung von Druckwalzen

Beim Bedrucken von Tüten wurde für die Reinigung der Druckwalzen ein Lösungsmittel verwendet, das Isopropanol, 2-Methylpropan-1-ol und Heptan enthielt. Die Substitution von lösemittelhaltigen Farben durch wasserbasierte Farben löste das Problem: Für die Reinigung der Druckwalzen war das genannte Lösungsmittel nicht mehr notwendig. (Das Lösungsmittel wird jetzt üblicherweise durch Wasser und Ammoniak substituiert).

Alternatives to phthalates in toys and childcare articles.

In this study a number of alternative plasticisers to the phthalates DEHP (Di (2-ethylhexyl) phthalate), DBP (Di-n-butyl phthalate) and BBP (Butyl benzyl phthalate) are described and assessed. Suitable alternative plasticisers have been identified for most applications of the phthalates, and ten of these have been assessed in detail.

Substitution of isopropanol, 2-methylpropan-1-ol and heptane in the cleaning of printing rolls

A solvent containing isopropanol, 2-methylpropan-1-ol and heptane was used in the cleaning of printing rolls used for bag printing. The previous substitution of organic inks by water based inks solved the problem since solvents were no longer necessary for the cleaning of rolls (the solvent is usually substituted by water and ammonia).

Fire resistant composition in particular for energy or telecommunication cables.

The substitution originates from a patent registration filed in 2006 concerning the substitution of different halogenated polymers used as flame retardants with non-halogen thermoplastics with cork as a fire retardant filler. By mixing in cork in the composition the heat release rate for the polymers decreased significantly, resulting in a more flame resistant material.

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.

An alternative to PVC in wires and cables. A kind of plastic completely free from halogens, BFR´s (brominated flame retardants), PVC and plasticizers.

Arnitel® XG, produced by DSM, is an engineering plastic completely free of halogens, BFR´s (brominated flame retardants), PVC and plasticizers. The applications of the plastic are primarily in wires and cables intended for use in consumer electronics. Although the plastic is free from brominated flame retardants it still possesses good flame retardancy, as well as chemical and temperature resistance. These properties make Arnitel XG a possible alternative to PVC in wires and cables.

Dimethyl sulfoxide as alternative solvent

Dimethyl sulfoxide (DMSO) is an efficient polar aprotic solvent in numerous applications. It may be used as an alternative to N methylpyrrolidone (1-Methyl-2-pyrrolidone), dimethylformamide or methylene chloride (dichloromethane) and other solvents in pharmaceuticals, agrochemicals, fine chemicals, electronics and cleaning.

Substitution von PVC und Phthalatweichmachern in Teppichrückseiten durch ein Materialgemisch (EcoWorx), dessen Hauptbestandteil ein lebensmittelechtes Polyethylen mit geringer Dichte ist (LDPE).

Ein Teppich besteht aus zwei Hauptelementen, dem Nylonoberflächenflor und der Teppichrückseite. Die Rückseitensysteme stellen eine bedeutende Investition von Materialien, Technologie und Performance dar. Shaw's Ziele waren, den Teppich nach den "Cradle to Cradle" Designprinzipien zu überarbeiten, um gefährliche Stoffe zu eliminieren, und das Recycling des Oberflächenflors und der Teppichrückseite nach Gebrauch zu ermöglichen. Die Verwendung der branchenüblichen PVC-Teppichrücken war mit diesen Zielen nicht vereinbar. Die Ersatzmaterial eingesetzten Rückseiten aus Polyolefin erfüllen alle Preis- und Leistungsansprüchen und ermöglicht es, das Produkt vollständig zu recyclen.
