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.

Alternatives for wood varnishes containing solvents

Alternative wood varnishes products based on water can be identified by applying GISBAU (German hazardous substances information system for the construction sector). Naphtha (petroleum), hydro desulfurized heavy and 2-Butanone oxime classified as carcinogens can be replaced by safer alternative.

Alternatives for accelerating admixtures for sprayed concrete

A certain group of accelerating admixtures for sprayed concrete containing hazardous chemicals can be replaced by safer alternative products. Most large producers of concrete admixtures offer a variety of products. The decision is taken by the customer and its special demands. The institution for statutory accident insurance and prevention in the construction industry (BG BAU) in Germany offers advice on how to choose the safest products from a chemical hazard point of view, and still maintaining a good function.

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.

Comparison of surface treatment agents for wood, focusing on chemical hazards

Alternative parquet lacquer based on acrylic dispersions can be identified by applying GISBAU (German hazardous substances information system for the construction sector). In this example naphtha (petroleum), hydrotreated heavy classified as a carcinogen and 1-Methoxypropan-2-ol can be replaced by safer alternative.

A biodegradable, protein-based biopolymer to replace acrylic resins and their additives in textile printing

This case story describes an alternative to acrylic resins used in textile printing. The use of acrylic resins is problematic since these are sensitisers and also since they require the use of additional additives that may also be problematic, such as alkyl phenols, phthalates and organotins. Grafco Srl has developed an alternative polymer based on milk-protein that could replace the acrylic resins along with the required additives.

An alternative to PVC and phthalates in high density plastisol prints.

PVC and phthalates have been extensively used for plastisol prints in textile applications. This case story describes the substitution of PVC and phthalates by silicon prints.

An alternative to APEO to reduce yellowing in polyamide, polyester and their blends with elastane fibres during heat-setting.

This case story describes the substitution of alkylphenol ethoxylates (APEO) in the textile industry. The company performed an investigation of possibilities to substitute APEO for reducing yellowing in polyamide, polyester and their blends with elastane fibres during heat-setting. They identified and implemented fatty alcohol polyglycol ether as a suitable alternative.

Substitution of decroline with sodium dithionite or borohydride in textile industry

Decroline is a chemical compound used in textile industry in applications that require a reducing agent (bleach agents, reduction stage in vat-dying process, rongeant print and others). The main hazard issue associated with the use of the substance is that when it is used as a reducing agent, formaldehyde is formed. This case story describes the substitution process of a company to find safer alternatives to decroline for textile industry. This process identified sodium dithionite as a feasible alternative, and sodium borohydrate as a promising candidate .
