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!

Mushroom technology to replace plastic foam packaging

Alternative protective material that uses mushroom roots to transform agricultural waste products into strong and compostable packing materials and insulation.

Substitution of PFC in paper with natural greaseproof paper.

This example concerns an alternative way to obtain grease-proof properties in papers used for cooking, baking or packaging food. Today, paper used for packaging of foodstuffs that require some grease resistance is made using chemicals such as perfluorinated compounds, these compounds are however associated with both human and environmental hazards. The technique described here provides a grease-proof surface by mechanically refining the cellulose fibers without the use of harmful chemicals.

Substitution von perfluorierten Verbindungen (PFC) in Papier durch natürliches fettdichtes Papier

Dieses Beispiel betrifft eine alternative Möglichkeit, fettdichte Eigenschaften von Papieren, die beim Kochen, Backen oder der Verpackung von Lebensmitteln verwendet werden, zu erwirken. Heutzutage wird zur Verpackung von Lebensmitteln Papier mit fettabweisender Wirkung eingesetzt, das unter der Verwendung von Chemikalien wie perfluorierten Verbindungen hergestellt wird. Diese Verbindungen werden allerdings sowohl mit Gefahren für den Menschen als auch für die Umwelt in Verbindung gebracht werden. Die hier beschriebene Technik bietet eine fettdichte Oberfläche durch die mechanische Veredelung der Zellulosefasern ohne die Verwendung von schädlichen Chemikalien.

Advisory methods to the substitution of chemicals in graphical production

A number of methods for substitution of chemicals specific to the printing industry have been developed and tested. The results of this work are described in a report and have in addition been integrated in a prototype of a software tool. This report and particularly the final version of the software can support graphic industry in the process of chemical substitution.

DecaBDE and Alternatives in Electrical and Electronic Equipment (EEE)

The case summarises information from a report from Danish Environmental Protection Agency (EPA) on the use of the brominated flame retardant DecaBDE in electrical and electronic equipment (EEE), and describes suitable alternatives to Deca-BDE. The study has not identified any application of Deca-BDE in EEE for which substitution is not possible, from the scientific or technical point of view. The report lists 25 alternative substances. Some of these are halogenated and will not be listed in this case description.

Potentially environmentally sounder alternatives to PFOS compounds and PFOA

Perfluorooctanesulfonate (PFOS), and a number of related perfluorinated compounds (perfluorooctanoic acid (PFOA)) are used in numerous industrial and consumer products. These compounds have been recognised as hazardous to health and environment and give rise to increasing concern. The example is based on a report from the Danish Environmental Protection Agency (EPA), evaluating whether suitable less hazardous alternatives can be found. The compounds discussed in the report are based on telomers, silicone, aliphatic alcohols and acrylates. The compounds are discussed as groups and not as single products.

SUBSPORTplus Specific Substances Alternatives Assessment – Bisphenol A

Bisphenol A is one the 10 specific substances or substance groups for which a detailed alternatives assessment has been performed by SUBSPORTplus according to a common methodology. In this document the hazard profile and identified uses of bisphenol A can be found as well as the identification, assessment and comparison of alternatives for three of its uses.

SUBSPORTplus Specific Substances Alternatives Assessment – Nonylphenol and Ethoxylates

Nonylphenols and their ethoxylates have been used on a large scale, in different, applications, because of their properties and affordable prices. Though they have been restricted at EU level in 2005 and even earlier by voluntary actions, there is still evidence of their production and use in EU. Because of their effects on health and environment, mainly their endocrine disrupting activity, it is necessary to look for alternatives.

A potential alternative to the use of Bisphenol A as a colour developer in thermal paper.

The Jegrelius Institute initiated a project in 2011 which was aimed at evaluating several alternatives to Bisphenol A (BPA) used as a colour developer in thermal paper that was being supplied by companies. One part of the project was to investigate what compound companies used instead of BPA in paper manufactured as bisphenol-free. After the project one likely candidate which was not a bisphenol-type compound was identified; Pergafast 201.

A bio-based polymer with multiple applications as substitute for poly(ethylene terephthalate)

Poly(ethylene terephthalate), better known as PET, is a material used on large-scale l that impacts in a negative way terrestrial and aquatic environment because is not biodegradable. PET can be substituted by a bio-based polymer with properties that also make it usable in a variety of other applications.
