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!

Substitution of subtilisins in manual cleaning of flexible endoscopes in hospitals

In a hospital in the Capital Region of Denmark cleaning of flexible endoscopes with enzymes was substituted by a product based on triethanolamine hereby reducing the risk of allergy. The substitution can only be performed if the succeeding machine wash is not based on aldehydes.

Alternatives to Chromic Acid Cleaners in Laboratories

Chromic acid is widely used in many laboratories for cleaning glassware. Because of the hazards for health and environment some alternatives have been developed as commercial products, but also as laboratory-made substitutes.

Substitution of formaldehyde in bathroom cleaning products

A cooperative cleaning company decided to try to substitute all products containing hazardous chemicals by safer alternatives.

Substitution of sulphuric acid with hydrochloric acid for degreasing metal before zinc and chromium plating.

Metallic coating on metal parts is often performed by galvanic processes. To achieve good-looking surfaces of good quality it is necessary to first clean the items. Earlier the company used sulphuric acid for pickling. The acid was heated and therefore some of it evaporated from the tank. By substituting sulphuric acid with hydrochloric acid pickling not only became more efficient, moreover, hydrochloric acid does not need to be heated.

Substitution of gasoline with a combination of ethanol based all-purpose cleaner and window cleaner for cleaning of medical equipment.

Gasoline is used to clean medical equipment in hospital and laboratories. It was discovered that gasoline can readily be substituted with an ethanol based all-purpose cleaner. For hospital and laboratory glassware, a window cleaner should also be used for best results.

Verwendung eines Infrarot-Lackentferners als Alternative zum chemischen Abbeizen

Bei der Renovierung eines älteren Exerzitien Hauses wurde anstelle von Chemikalien ein Infrarotgerät für die Entlackung verwendet. Die spezielle Wärmeintensität des Geräts senkt die Risiken gefährlicher Rauchemissionen und Bränden.

Infrared paint stripper used as alternative to chemical stripping

An infrared device was used instead of chemicals for paint stripping when renovating an elderly retreat house. The device uses heat at an intensity that lowers the risks of hazardous fumes emissions and fires.
