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.

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.

Fire-resistant and flame proof coating for polymeric thermoplastics and thermoset resins.

A surface coating consisting of fire retarding and smoke suppressing constituents dispersed in an essentially non-toxic, water based adhesive binder. The entire invention therefore consists of six different functional groups which respective functions will be explained below, the different groups are: catalyst/initiator, expendable graphite, source of carbon which additionally forms water, a blowing agent, cement and ceramics.

Chemical treatment of rubber, wood, leather or metal which protects, preserves and renews the surface of the material. An alternative to carbon black.

This document describes a process for protecting, preserving and renewing surfaces, especially rubber and other natural and synthetic polymers including wood, leather, painted surfaces and metal. The material to be treated is soaked with an aqueous solution of substituted or unsubstituted dimethylpolysiloxane. This is done in several stages with other solutions such as diethylene glycol and/or glycerine. This treatment reduces the impact of deleterious effects such as ozone, ultraviolet radiation and environmental causes to the appearance of especially rubber parts used for example in automobiles.

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.

Surface treatment of metals and plastic

This document describes the best available techniques for surface treatment of metals and plastics. Substitution possibilities for EDTA, PFOS, zinc cyanide, copper cyanide and hexavalent chromium are mentioned.

Green Glue - eine Alternative zu Methanol freisetzendem Parkettkleber auf der Basis von Silanen.

Der europäische Markt für Holzbodenbeläge (Parkett) produziert über 100 Millionen Quadratmeter pro Jahr. Ungefähr 70% der Holzböden werden unter Verwendung spezieller Kleber bei einem geschätzten Verbrauch von 70 Millionen Litern pro Jahr verlegt. Die meisten von ihnen enthalten flüchtige organische Verbindungen (VOCs) und andere gefährliche Stoffe, die gesundheits- und umweltschädlich sind. Green Glue ist ein umweltfreundlicher Kleber für die Verlegung von Holzfußböden. Es enthält weder VOCs noch Isocyanate oder Zinn und gibt kein Methanol ab.

Life cycle assessment of three paints

An assessment of environmental and occupational health impacts of a powdered paint, a solvent based paint and a water-based paint showed that xylene, titanium dioxide and TGIC are first priority to substitute. Beta hydroxy alkylamide is suggested as an alternative for TGIC . No successful chemical alternative for xylene was found, but other water based paint systems could be used. No alternative to titanium dioxide was suggested.

Corrosion protection within industrial surface treatment

For industrial surface treatment the products are usually chosen on a basis of their technical properties. These products, however, can have serious consequences for the working environment and the external environment. The brochure that provides the basis for this case story contains a ranking system used for industrial surface treatment which takes the working environment and the external environment into account.

Green Glue - alternative for methanol releasing silane based parquet adhesives

The European wood flooring (parquet) market produces over 100 million square meters per year. Approximately 70% of wood floors are installed by bonding using specialised adhesives, with an estimated annual consumption of 70 million litres. Most of them contain volatile organic compounds (VOCs) and other hazardous substances which are harmful to human health and the environment. Green glue is an environmentally friendly adhesive for wood-flooring installation. It does not contain VOCs, isocyanates or tin and does not release methanol.

Restaurierung alter Herrenhäuser unter Verwendung umweltfreundlicher, Kaseinbasierter Farbe

Kaseinfarbe könnte als Alternative zu lösungsmittelbasierter Acryl-Wandfarbe verwendet werden. Die Restaurierung eines historischen Herrenhauses mit Kaseinfarbe war unter den Gesichtspunkten der Qualität und der Umweltfreundlichkeit ein Erfolg.
