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 cyclododecane or camphene with tricyclene or menthol as a volatile binding media in conservation and archaeology.

Volatile binders are used in conservation and archaeology as hydrophobic protective coatings for fragile objects during excavation, transport or handling. Cyclododecane and camphor are two examples of binders that can be readily replaced by tricyclene or menthol. There are however limitations to this substitution which are important to bear in mind, tricyclene is for example shorter lasting than cyclododecan.

Substitution of polystyrene by natural cork in houses insulation.

Extruded polystyrene plates were substituted by expanded black chipboard plates (made of natural cork) during house construction in Mallorca, Spain. Polystyrene is primarily based on styrene, an endocrine disruptor and polystyrene plates contain other additives such as 1,2,5,6,9,10-Hexabromocyclododecane (HBCDD), an halogenated flame retardant classified as persistent, bio accumulative and toxic (PBT), highly polluting to the environment. Cork is a natural product that does not imply any hazard to human health.

Thymolphthalein als Alternative zu Phenolphthalein in Tests zur Karbonatisierung von Beton

Phenolphthalein wird im Karbonatisierungstest von Beton verwendet. Es ist jedoch ein anerkanntermaßen karzinogen wirkender Stoff. Thymolphthalein ist mit guten Ergebnissen als Alternative verwendet worden.

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.

Thymolphthalein as alternative to phenolphthalein in concrete carbonation testing

Phenolphthalein is used in carbonation tests of concrete. It is, however, a recognised carcinogen. Thymolphthalein has been used as an alternative with good results.

Substitution of PVC floorings

In the construction of the headquarters of the Center for Research and Energetic Resources (CIRCE) in Zaragoza, Spain, it was decided to avoid the use of toxic materials. PVC floorings were substituted with natural linoleum, as PVC contains vinyl chloride a carcinogenic substance and phthalates, which are endocrine disruptors.

Life cycle assessment of three paints

An assessment of environmental and occupational health impacts of a powdered paint, a solvent based paint and a water-based paint showed that xylene, titanium dioxide and TGIC are first priority to substitute. Beta hydroxy alkylamide is suggested as an alternative for TGIC . No successful chemical alternative for xylene was found, but other water based paint systems could be used. No alternative to titanium dioxide was suggested.

Corrosion protection within industrial surface treatment

For industrial surface treatment the products are usually chosen on a basis of their technical properties. These products, however, can have serious consequences for the working environment and the external environment. The brochure that provides the basis for this case story contains a ranking system used for industrial surface treatment which takes the working environment and the external environment into account.

New injectable mortar/chemical anchor for construction projects

Injectable mortar is used to join concrete construction elements, for example in the construction of buildings. Conventional products contain allergenic substances and require specialist application training. Furthermore, the material has to be dealt with as hazardous waste. Following environmental demands from one of Skanska’s clients, the supplier developed a new product, which involved the removal of one hazardous substance and the significant reduction of another. In addition, the new product requires no specific safety measures during application.
