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!

Cables without lead, PVC and phthalates

A Danish producer of cables has developed cable installation without lead, PVC and phthalates. The new cable type NOPOVIC® is based on a mixture of non-halogen polymers such as polyethylene (PE), polypropylene (PP) and ethylene-vinyl-acetate (EVA) copolymers with added non-flammable minerals like magnesium and aluminium hydrates.

Glass-pack filter as alternative to sand and zeolite filters for water treatment

Filter packs made from crushed recycled glass can replace filters made of crystalline silica- containing materials, such as sand or zeolites. They provide good filtration quality and economic advantages.

Improvement in biodegradability and pharmaceutical properties of cytostatics for tumour treatment.

Certain pharmaceuticals including some cytostatics are carcinogenic, mutagenic, teratogenic and fetotoxic. Cytostatics and their metabolites are excreted by patients into waste water. In laboratory testing, the frequently used isomeric anti-tumour agent Ifosfamide was shown to be non- biodegradable. It is not eliminated in municipal sewage treatment plants, and therefore passes into the effluent. Structural modified compounds like Glufosfamide are still active against tumours, and in contrast to Ifosfamide are inherently biodegradable.

Potentially environmentally sounder alternatives to PFOS compounds and PFOA

Perfluorooctanesulfonate (PFOS), and a number of related perfluorinated compounds (perfluorooctanoic acid (PFOA)) are used in numerous industrial and consumer products. These compounds have been recognised as hazardous to health and environment and give rise to increasing concern. The example is based on a report from the Danish Environmental Protection Agency (EPA), evaluating whether suitable less hazardous alternatives can be found. The compounds discussed in the report are based on telomers, silicone, aliphatic alcohols and acrylates. The compounds are discussed as groups and not as single products.

Magnesium hydroxide as alternative to caustic soda in biological treatment of wastewater at a chicken processing plant

A plant for chicken processing replaced caustic soda (sodium hydroxide) with magnesium hydroxide in the secondary treatment of waters. This reduced corrosion risks, lowered the quantity of alkali used and improved process stability.
