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.

Surface treatment of plywood

Insurface treatment of plywood an acid-cured primer and top-by 94 % and reduces the amount and number of classified ingredients with carcinogenic and reprotoxic effects. The alternative still contains a small percentage of an additive that may cause cancer. Further research isneeded to eliminate this.

Ein Holzschutzmittel ohne Schwermetalle, halogenierte und Phosphor-Verbindungen. Verleiht flammhemmende Eigenschaften und schützt gegen Fäule.

Um Holzwerkstoffe gegen Fäulnis zu schützen, werden normalerweise Biozide wie Kupfer, Chrom und Arsen durch Vakuum-Druck-Imprägnierung aufgebracht. Diese Biozide beeinträchtigen nicht nur die Fäulniserreger, sondern auch die meisten anderen Lebewesen in der Nähe des behandelten Materials. OrganoWood ist ein von Bioziden freies Holzschutzprodukt, das Holz für Fäule unzugänglich macht, indem es an die Oberfläche der Holzfasern bindet. OrganoWood verleiht dem behandelten Holz auch gute flammhemmende Eigenschaften, ohne dass halogenierten und phosphorhaltige Stoffen verwendet werden.

Surface treatment panels for walls and ceilings

Insurface treatment of panels for walls and ceilings (MDF-plates) an acid-cured primer and top-coating can be substituted with a water-based primer and an UV-cured top coating. This reduces the amount of coating used, reduces the solvent emissionby 96 % and reduces the amount and number of classified ingredients with carcinogenic and reprotoxic effects. The alternative still contains a small percentage of an additive that may cause cancer. Further research isneeded to eliminate this.

Surface treatment in wood working industry

Insurface treatment in the wood- and furniture industryacid-cured primer and top-coating can be substituted with a water based primer and an UV-cured top coating. This reduces the amount of coating used, reduces the solvent emissionby 96 % and reduces the amount and number of classified ingredients with carcinogenic and reprotoxic effects. The alternative still contains a small percentage of an additive that may cause cancer. Further research is suggested to eliminate this.

Substitution of formaldehyde by starch in adhesives used in the manufacture of wood particle boards

Adhesives used in the manufacture of wood particle boards (chipboard) contain, among other hazardous chemicals, formaldehyde (carcinogen and sensitiser). Employees are exposed to high concentrations of formaldehyde during the manufacture of wood particle boards. The union’s (CCOO) regional health and safety department in Galicia, Spain, put forward an initiative for the substitution of formaldehyde by starch.

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.

A wood treatment product completely free from heavy metals, halogenated and phosphorus compounds. Gives flame retardant properties and protects against rot fungus.

In order to protect wooden material against rot-fungi, biocides such as copper, chromium and arsenic, are commonly applied through vacuum-pressure impregnation. These biocides affect not only rot-fungus, but most living creatures being close to the treated material. OrganoWood is a wood-treatment product, completely free from biocides, that renders the wood inaccessible for rot fungi by binding to the surface of the wood fibres. OrganoWood also confers good flame retardant properties to the treated wood without use of halogenated and phosphorus containing compounds.

A safer alternative to protect wood from moisture.

This substitution example is based on a patent registration document. The invention relates to a mixture protecting wood from moisture. The mixture contains crude tall oil or another oil containing free fatty acids and/or resin acids. Present in the wood protecting mixture is also at least one other substance from a group including native neutral agents of wood and salts formed by di- or polyvalent cations. The details for how to make such a mixture is described in detail below.

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.
