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.

Laser cleaning of waffle irons in production line

Food manufacturing and processing company cleaned waffle irons residues in a baking line automatically by a solid-state laser. Before substitution parts are manually cleaned with sodium carbonate and brushes.

Implementation of a health and safety management system for chemical products

The Spanish branch of the company BSH implemented a health and safety management system for chemical products in the manufacture of electric home appliances to avoid the use of toxic chemicals in the manufacturing and cleaning process. The inclusion of this methodology in the process of recognition of chemical product allowed the substitution of some highly hazardous chemicals. For example, methanol for glass cleaning was substituted by a conventional glass cleaner.

Druckwasser als Alternative für die Reinigung von Sieben im Rotationssiebdruck für den Textilbereich

Das Reinigen von Sieben für den Rotationssiebdruck mit gefährlichen Stoffen wie Dichlormethan und Phenol oder Flusssäure kann durch eine sicherere Alternative ersetzt werden, die Wasser verwendet. Einige Textilbetriebe in Asien haben eine Reinigungsmaschine, die Wasser unter hohem Druck verwendet, eingeführt und sind zufrieden mit den erzielten Ergebnissen sowie mit den gesundheitlichen und ökologischen Aspekten.

Pressurised water as alternative to cleaning of rotary screen in the textile sector

Stripping rotary screens with hazardous chemicals like dichloromethane and phenol or hydrofluoric acid, can be replaced by a safer alternative using water. Textile companies in Asia that introduced a cleaning machine using high pressure water are satisfied with the results and with the safety and environmental performance.

Water based cleaning machine for metal parts

A chemical-free device that uses ultra sounds and water can replace hazardous cleaning agents like organic solvents or strong alkali solutions.

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.

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.

Assessment, development and demonstration of alternatives for decamethylcyclopentasiloxane

This document describes the substance decamethylcyclopentasiloxane or D5, a substance used increasingly as a substitute to different halogenated solvents. The compound has latterly shown undesirable properties. This study has investigated the availability of alternatives to the compound for the uses dry cleaning, maintenance cleaning and as an ingredient in cosmetic products. For the first two uses some alternatives using new technologies, including liquid carbon dioxide and ultrasonic cleaning were mentioned as safer alternatives. The document focuses on function and cost aspects of the 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.

Substitution of a dish-washing compound containing Trisodium nitrilotriacetate (NTA salt) in a hospital

In the kitchen of the hospital Parc Taulí in Barcelona a dish-washing detergent containing trisodium nitrilotriacetate (NTA salt) was used. Trisodium nitrilotriacetate is a carcinogenic chemical and was substituted by a product of the same manufacturer that does not contain NTA salts.
