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.

In order to utilize information in the best way, please take note of the SUBSPORTplus methodology on case stories!

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.

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.

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.

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).

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.

Targeted improvement of the environmental characteristics of a persistent complexing agent: ethylenediaminetetraacetic acid (EDTA)

Ethylenediaminetetraacetate acid (EDTA) is used as a complexing agent in many chemical products. It is persistent and can remobilize metal ions form sediments in the environment. Ethylenediamine -N,N'-disuccinic acid (EDDS) is a structural isomer of EDTA, less hazardous for the environment and has even better performance characteristics than EDTA depending on the application.

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.

Water-based PU coating technology for textiles

Coated textiles find use in industries as diverse as automotive, sportswear and fashion apparel & footwear, as well as myriad technical applications. Covestro launched in 2014, INSQIN® which is a offer of waterborne and solvent-free PU coating technology for textiles. The alternative technology allowing complete substitution of dimethylformamide (DMF) normally used in this process.
