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.

Fassadenreinigung mit Hilfe von Trockeneisstrahlung für die Restaurierung von Denkmälern in Prag

Fassadenreinigung kann mit Hilfe von Chemikalien oder durch das Abstrahlen mit verschiedenen Mitteln erreicht werden. Die chemische Reinigung erfolgt oft mit gefährlichen Stoffen, wie Dichlormethan oder Methylpyrrolidon. Sandstrahlung ist auf Grund von kristallinem Siliziumdioxid, ein karzinogener Stoff, gefährlich. Das Abstrahlen mit Trockeneis könnte eine sicherere Alternative sein. Ein Beispiel der Verwendung bei der Restaurierung alter Monumente in Prag wird vorgestellt.

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.

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.

Ethyl lactate and methyl soyate as bio based alternatives to chlorinated and other petroleum based solvents

Bio based solvents can replace petroleum derived solvents in various applications like adhesives and coating, inks and cleaning products.

Facade cleaning using dry ice blasting for monument restoration in Prague

Facade cleaning may be performed with chemicals or by using blasting with various media. Chemical cleaning is often done with hazardous substances like dichloromethane or methyl pyrrolidone. Sandblasting is hazardous due to the crystalline silica, a carcinogen. Using dry ice blasting may be a safer alternative. An example of its use in restoring ancient Prague monuments is presented.

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 von Formaldehyd durch Wasserstoffperoxid zur Dekontamination von biologischen Laboratorien und Tierhaltungsanlagen

Die Dekontamination von Laboratorien und Tierhaltungsanlagen der Schutzstufe 2-4, sowie von HEPA-Filteranlagen (siehe TRBA 100/120) wurde lange Zeit mit Formaldehyd durchgeführt. Formaldehyd kann in einem alternativen Verfahren durch das weniger gefährliche Wasserstoffperoxid unter einfacheren Verwendungsbedingungen substituiert werden.

Alternatives for cleaners for industrial surfaces

Alternative special cleaner can be identified by applying GISBAU (German hazardous substances information system for the construction sector). A strong alkaline cleaner (pH 13) can be replaced by an alternative with pH 9,5.

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.
