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.

Alternatives for parquet adhesive products

Alternative parquet adhesive products can be identified by applying GISBAU (German hazardous substances information system for the construction sector). In this example parquet adhesive containing acetone and ethanol can be replaced by a water-based product.

Fire-resistant and flame proof coating for polymeric thermoplastics and thermoset resins.

A surface coating consisting of fire retarding and smoke suppressing constituents dispersed in an essentially non-toxic, water based adhesive binder. The entire invention therefore consists of six different functional groups which respective functions will be explained below, the different groups are: catalyst/initiator, expendable graphite, source of carbon which additionally forms water, a blowing agent, cement and ceramics.

Assessment, development and demonstration of alternatives for 1,2-trans-dichloroethylene

This is a report from a project investigating the alternatives to 1.2-transdichloroethylene in cleaning of printed circuit boards and in aerosol cleaning. For the circuit boards is suggested a change of process which does not require solvent cleaning. For aerosol cleaning products based on water, soy or acetone are recommended as alternatives.

Assessment, development and demonstration of alternatives for n-methyl pyrrolidone

This is a report from a project investigating the alternatives to n-methyl pyrrolidone. The investigated uses for the substance are stripping of paint and furniture, precision cleaning, pharmaceutical penetration enhancer and in personal care products. For stripping and precision cleaning a more thorough alternatives assessment including function and cost was performed, while for the pharmaceutical and personal care applications it was only stated that corresponding products exists without having to use this substance. For stripping the suggested alternatives were based on benzyl alcohol and/or acetone, while for precision cleaning organizational changes were suggested.

Alternatives for concrete release products

Alternative concrete release products based on mineral oil can be identified by applying GISBAU (German hazardous substances information system for the construction sector).

Assessment, development and demonstration of alternatives for n-propyl bromide

This document describes possible alternatives to n-propyl bromide in different types of aerosol cleaning, industrial precision cleaning and as an adhesive for polyurethane in furniture. The alternative includes both alternative cleaners, such as water based systems, and alternative adhesives including acetone and latex, as well as alternative cleaning technologies including laser, deionised water and carbon dioxide pellet blasting. The document focuses on function and cost aspects of the alternatives.

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.

Assessment, development and demonstration of alternatives for parachlorobenzotrifluoride

This document describes the emerging solvent parachlorobenzotrifluoride, a solvent increasingly used as an alternative to other solvents phasing restrictions. The document describes the different uses of the solvent and identifies available alternatives. Investigated uses include automotive body cleaning and cosmetic stain removal. Acetone and soy-based solvents are among the mentioned safer alternatives. Function and costs of the different alternatives are also evaluated.
