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!

Formaldehyde free preservative for starch adhesives

Formaldehyde is a common preservative but is IARC carcinogen and CLP skin sensitiser. An alternative product made of sodium chloride and compounds extracted from berries is available as bactericide for starch adhesives.

Toner powder derived from soybeans as alternative to petroleum-based printing toners

Petroleum-based printing toners consume a lot of non-renewable resources and have negative environment, climate and health impacts. Soybean derived powder is used as an alternative to produce laser printer toners, at affordable price and with good printing quality.

Targeted improvement of the environmental characteristics of a persistent complexing agent: ethylenediaminetetraacetic acid (EDTA)

Ethylenediaminetetraacetate acid (EDTA) is used as a complexing agent in many chemical products. It is persistent and can remobilize metal ions form sediments in the environment. Ethylenediamine -N,N'-disuccinic acid (EDDS) is a structural isomer of EDTA, less hazardous for the environment and has even better performance characteristics than EDTA depending on the application.

Substitution of formaldehyde in bathroom cleaning products

A cooperative cleaning company decided to try to substitute all products containing hazardous chemicals by safer alternatives. A deodorising product used in bathroom cleaning that contained sodium hydroxide and formaldehyde (sensitiser and carcinogen) was therefore substituted to a product taking into account health and environmental criteria

Cyclopentyl methyl ether as alternative to solvents that have a high risk of explosionand are hazardous for health

Cyclopentyl methyl ether (CPME) can be used as substitute for solvents like tetrahydrofuran (THF), 2-methyl tetrahydrofuran (MeTHF), methyl tert butyl ether (MTBE) or 1,4 dioxane, that may generate high risks for safety and are also classified as hazardous to health.

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.

Formaldehydfreie Bindemittel für die Herstellung von Holzwerkstoffen

Harnstoff-Formaldehyd Klebstoffe sind in der holzverarbeitenden Industrie weit verbreitet. Baumaterialien stellen nach wie vor eine wesentliche Quelle von Formaldehydabgabe in Innenräumen dar. Es ist deshalb notwendig, alternative formaldehydfreie Bindemittel für Holzwerkstoffe zu entwickeln. Das französische Projekt "Panneaux verts" entwickelte einen Extraktionsprozess für Tannine, der auf Flüssig-Extraktion und Lignin basiert. Diese extrahierten Verbindungen wurden erfolgreich in Klebstoffe eingebracht und damit formaldehydfreie Kleber entwickelt. Die mechanischen Eigenschaften von Holzfaserplatten, die mit dem neuen Klebstoff hergestellt wurden, entsprachen der europäischen Norm.

Glues from renewable resources for panel board manufacture

Urea-formol adhesives are largely used in the wood products industries. Construction materials are the main source of formaldehyde emissions in the indoor environment. Therefore, it is necessary to find new natural alternatives to produce wood adhesives. The project allowed developing and validating extraction process for tannins, based on aqueous extraction, and lignin. These extracted compounds were successfully inserted in adhesives to develop a formula without formaldehyde. The mechanical properties of the panel board produced with this new adhesive responded to European standard.

Vegetable oils can be used as sustainable insulating and cooling liquids in transformers

It was estimated that globally each year about 5.7 million tons of fresh transformer oil is needed. Substitution of mineral oil by vegetable oil would be an important contribution to sustainable development.
