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 to 2-methoxyethanol as put forward by the European Chemicals Agency (ECHA)

This document concerns the general toxicity of 2-methoxyethanol and some common alternatives to its use in different applications. The most common substitutes for 2-methoxyethanol are: PGME, EGBE, ethylene glycol monopropyl ether (EGPE) and their acetates (PGMEA, EGBEA, EGPEA). The decision which alternative to use depends on what application 2-methoxyethanol is currently used in.

Reinigung von Trommelbremsen in Lastwagen und Transportern mit erhitztem Leitungswasser

Eine Reparaturwerkstatt hat einen typischen Bremsenreiniger durch ein neues Gerät ersetzt, das erhitztes Leitungswasser verwendet. Das heiße Leitungswasser (95°C) wird in dem kleinen und mittleren Unternehmen (KMU) für die Reinigung von Lastwagen- und Transportertrommelbremsen von Matsch, Staub und Sand sowie zu Reparatur- und Wartungszwecken verwendet.

Cleaning of lorry and van drum brakes by heated tap water

A small and medium sized service station has substituted a typical brake cleaner with a new equipment using heated tap water. The heated tap water (95°C) is used for the cleaning of lorry and van drum brakes from mud, dust and sand for repair and maintenance purposes.

Out phasing of dimethyl formamide (DMF) and cobalt dichloride in piping production.

By introduction of new production equipment, the pipe producing company Logstor, have been able to phase out dimethylformamide (DMF) as a cleaning solvent. Instead most cleaning of mixing heads and sprayer heads is done mechanically, and in rare cases a Dowanol (1-methoxypropan-2-ol) bath is used. Cobalt dichloride containing silica gel desiccant have been substituted with a cobalt free desiccant, which is performing even better than the old one.

Thread- locks used in production

In afactory product with classified substances were previously used for thread lock. These substances were a potential risk in connection to breathing and skin contact. The products are now substituted to products without any classified ingredients.

Safer Alternatives to Solvent Aerosol Automotive Cleaning Products

This is a report from a study with the aim to identify products for automotive cleaning that functions well and that contain low or no amounts of volatile organic compounds (VOC). The alternatives tested included acetone and a soy based product. This project could identify a number of cleaners with zero or low content of VOC, who functioned as well as or better than the high VOC cleaners.

Substitution von Borsäure durch Milchsäure als Biozid in Kühlschmierstoffen

Borsäure ist als reproduktionstoxischer Stoff der Kategorie EU 1B sowie als endokrin wirksamer Stoff eingestuft. Sie kann mit guten Ergebnissen durch Milchsäure substituiert werden, um das Wachstum von Bakterien und Pilzen in wassermischbaren Kühlschmierstoffen zu bekämpfen.

Substitution of boric acid by lactic acid as biocide in cooling lubricants

Boric acid is classified toxic for reproduction EU 1B and endocrine disruptor. It can be substituted by lactic acid with good results in keeping bacteria and fungi under control in water mixable cooling lubricants.

Ultra sound system as alternative to sodium hypochlorite for bacteria control in the cooling towers of a university

A university decided to switch to ultrasounds for controlling bacteria in its water cooling towers. The system proved effective and helped to cut costs with the previously used chemical biocide (sodium hypochlorite) but also with substances needed to counterbalance the corrosiveness of the biocide and its alkalinity.

Controlled hydrodynamic cavitation as alternative to chemical biocides and antiscaling agents

Controlled hydrodynamic cavitation may replace the use of hazardous chemicals for scale, bacteria and corrosion control in refrigerating and cooling systems. The method combines two side streams loops, one for cavitation the other for filtering and it has been applied in different sectors, including in a military facility where an allergy to biocides was reported for one of the maintenance employees.
