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!

Elimination of trichloroethylene in asphalt quality control laboratories

Trichloroethylene is used in quality control laboratories to determine the amount of bitumen in asphalt mixtures. Bitumen is a hazardous substance whose elimination or substitution by a less dangerous chemical is a health and safety priority. The elimination of trichloroethylene from the process is carried out through a small muffle furnace that burns the asphalt mix at the temperature of evaporation for bitumen. This procedure facilitates the calculation of bitumen percentage in the mix based on the weight difference.

Eliminierung von Trichlorethylen in Laboratorien zur Kontrolle von Asphaltqualität

Trichlorethylen wird zur Qualitätskontrolle in Laboratorien verwendet, um den Gehalt von Bitumen in Asphaltgemischen zu bestimmen. Bitumen ist ein gefährlicher Stoff, dessen Eliminierung oder Substitution im Hinblick auf Gesundheits- und Sicherheitsaspekte eine hohe Priorität zukommt. Die Eliminierung von Trichlorethylen aus dem Prozess wird mit Hilfe eines kleinen Muffelofen erreicht, der die Asphaltgemische bei der Verdunstungstemperatur von Bitumen verbrennt. Diese Prozedur ermöglicht die Berechnung des prozentualen Bitumengehalts eines Gemisches anhand des Gewichtunterschieds.

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.

Substitution of plastic paints by mineral-based paints in Metro Madrid

Madrid?s underground metropolitan transport company (metro) decided to substitute regular plastic paints which contained titanium dioxide, xylene and toluene, by mineral paints based on barium sulfate, quartz and mica that do not represent any health or environmental hazards and require less frequent maintece.

Substitution von Kunststofffarben durch mineralische Farben in der Madrider Metro

Der Verkehrsbetrieb der Madrider U-Bahn (Metro) beschloss, die regulären Kunststofffarben, die Titanadioxid, Xylol und Toluol enthalten, durch mineralische Farben zu ersetzen, die auf Bariumsulfat, Quarz und Glimmer basieren. Diese stellen keinerlei Gesundheits- oder Umweltgefahr dar und erfordern weniger häufig Instandhaltungsarbeiten.

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.

Database on alternatives to PVC. Building the future.

PVC is used extensively in the construction industry. During its full life-cycle PVC releases a significant amount of toxic chemicals harmful to human health. This article introduces a database with alternatives to the different uses of PVC in construction.

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 of PVC and phthalate plasticizer carpet backing by a mixture of materials (EcoWorx) the primary component of which is a food grade low density polyethylene (LDPE).

Carpet comprises two main elements, nylon face pile and backing. Backing systems represent a significant investment in materials, engineering and performance.Shaw’s goals were to re-engineer the carpet following “Cradle to Cradle” design principles to eliminate hazardous chemicalsand to facilitate recycling of the face pile and backing at the end of its life.The use of industry standard PVC backings was incompatible with these goals. The polyolefin replacement backing meets all PVC product and price performance criteria while allowing the product to be fully recycled.

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.
