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!

SUBSPORTplus Specific Substances Alternatives Assessment – Bisphenol A

Bisphenol A is one the 10 specific substances or substance groups for which a detailed alternatives assessment has been performed by SUBSPORTplus according to a common methodology. In this document the hazard profile and identified uses of bisphenol A can be found as well as the identification, assessment and comparison of alternatives for three of its uses.

Replacement of bisphenol A in food and beverage packing

Bisphenol A can be replaced with polyamide, a resin based on oil extracted from plants or isosorbide depending on the application.

Alternative lead-free method to the analysis of sucrose

Conventional polarization analysis uses lead acetate as clarifying agent for the sugar juice. An alternative method using near infrared polarimetry that does not need lead acetate was tested and provided good quality results.

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.

Copper sulphate as alternative to mercury monoxide catalyst in the Kjeldahl reaction

The Kjeldahl reaction developed to analyse nitrogen content of organic substances has been reviewed many times to optimise it and make safer for the users. A comprehensive handbook on various Kjeldahl analyses includes a chapter on catalysts that presents alternatives to mercury monoxide.
