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.

Mittlere bis große Kühlsysteme für Gebäude und Industrieanlagen: Kältemaschinen mit natürlichen Kühlmitteln.

Zwei dänische Unternehmen begannen mit der Herstellung von mittleren bis großen Kühleinheiten (50-400 kW), die einfache Kohlenwasserstoffe als Kühlmittel an Stelle von Fluorkohlenwasserstoffen verwenden. Die beiden Unternehmen produzieren rund 150 Einheiten pro Jahr hauptsächlich für den Binnenmarkt, aber der Export in andere Länder hat ebenfalls begonnen.

Practical guide for the substitution of hazardous chemicals by less harmful substances in industrial facilities.

This guide seeks to promote and support the substitution of toxic chemicals in industry. It includes a description of substitution criteria and introduces alternatives to the different uses of 12 toxic chemicals: arsenic, cadmium, chloromethane, zinc chromate, strontium chromate, dimethylformamide, formaldehyde, hydrazine, methylglyclol, ethylglycol, perchloroethylene and trichloroethylene.

Metal processor changes surface polishing technology and replaces chemical emulsion

Offering a wide range of metalworking services, the company used grinding equipment which required the use of a lubricating-cooling emulsion. The emulsion was expected to decrease the temperature of abrasive components during metal surface treatment processes. The lubricating-cooling emulsion contained substances that were hazardous both to human health and the environment, including CMRs and VOCs. One of the substances was formaldehyde, which is classified as carcinogen and sensitizer. Formaldehyde is included in the SIN list: https://sinsearch.chemsec.org/chemical/50-00-0.
The company wanted to phase out these substances. So, they changed the surface grinding system and modernised the existing grinding cycle. New grinding components were purchased and installed, and the emulsion with abrasives was replaced. The new equipment allows working without hazardous substances.

Five Chemicals Alternatives Assessment Study

An “alternatives assessment” methodology developed by TURI was used to evaluate the technical, economic, and environmental, health and safety feasibility of alternatives to the five chemicals for selected uses: lead, formaldehyde, tetrachloroethylene, hexavalent chromium, Di (2-ethylhexyl) phthalate (DEHP).

Medium to large size cooling systems for buildings and industrial plants: Chillers with natural refrigerants.

Two Danish companies have started a production of medium to large cooling units (50-400 kW) that utilize simple hydrocarbons as refrigerants instead of hydrofluorocarbons. The two companies make about 150 units per year, mostly for the domestic market but exports to other countries have started.

Substitution of epoxy resins containing naphtalene, ethylbenzene, naphta (heavy aromatic fractions) and titanium dioxide used for the painting of vehicles.

Substitution of a finishing compound based on epoxy resins containing carcinogens, endocrine disruptors, neurotoxicants and volatile organic compounds: naphtalene, 1,2,4 -trimethylbenzene, ethylbenzene, naphta (heavy aromatic fractions), titanium dioxide. Introduction of a water-based finishing compound in a repair workshop of a company specialized in bodyworks for buses.

An alternative to APEO processing chemicals for cotton fabric pre-treatment and after-treatment production in the textile industry for home textile products

This case story describes the substitution of chemicals containing alkylphenolethoxylates (APEO) in cotton processing in the Indian textile industry using alcohol ethoxylate surfactants.

Substitution von Formaldehyd als Gewebefixiermittel

Formaldehyd ist eine organische Verbindung, die als Gewebefixiermittel in der Mikroskopie und Histologie verwendet wird. Das Formaldehyd wurde durch ein Produkt mit dem gewerblichen Namen Fixall-his substituiert, das Ethanol, Isopropanol und Essigsäure enthält.

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.

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.
