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.

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.

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.

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.

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.

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).

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.

Dimethylformamide (DMF)-free Technology in PU-coated textile Fabric

Lidl decided to eliminate DMF containing PU-leather by using the groundbreaking DMF-free INSQIN®-technology for the coating of fabrics with PU. PU-Coated textiles are used in industries as diverse as e.g. fashion apparel &footwear, sportswear and automotive.

Bio-pitch as replacement for coal tar in the production of electrodes

Bio-pitch can be mixed with char-coal to obtain electrodes. The study presents results of tests carried out with bio-pitch electrodes obtained under various conditions from eucalyptus oil.

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.
