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.

Coating for industrial washing machines - from binder based on epoxy/polyester to polyester

A Danish company produces industrial washing machines. They substituted a paint based on epoxy/polyester with a paint based on polyester. This new product is not classified and is much better than the former used product, the technical performance is better and the energy consumption lower, which probably counterbalances a higher price.

Surface treatment of metals and plastic

This document describes the best available techniques for surface treatment of metals and plastics. Substitution possibilities for EDTA, PFOS, zinc cyanide, copper cyanide and hexavalent chromium are mentioned.

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.

Cleaning of casings of professional electro tools from release agents

Casings of professional electro tools made of aluminium die-cast and sand cast are cleaned in a spray plant and the surface is superficially etched by an alkaline agent. Formerly, tools were cleaned with pickle liquor containing hydrofluoric acid.

Reinigung von Motorrad-Kurbelwellen durch eine integrierte Vibrationseinheit

Ein Automobilhersteller integrierte eine Vibrationseinheit in die Produktionslinie, umMotorrad-Kurbelwellen aus Stahl von Kühlschmiermitteln und Spänen zu reinigen.

Components cleaning with deionised water

An international pump manufacturer cleaned components for pumps from drawing oils in a spray automatic machine using only deionised water. Formerly, a company used an alkaline cleaner for this application.

Cleaning of motorcycle crankshafts by integrated vibration unit

An automobile manufacturer integrated a vibration unit into the production line to clean motorcycle crankshafts made of steel from cooling lubricants and chips.

A new water repellent surface treatment which contain no fluorocarbons or isocyanates, to be used on textiles and other fibre-based materials.

Fluorocarbon and isocyanate containing mixtures have been used for many years as water repellent surface treatments of textiles and of other fibre-based materials. Today it is clear that many fluorocarbons (e.g. PFOA) degrade extremely slowly in nature and cause hormone disruption among many aquatic animals, whereas many isocyanates are toxics to humans. OC-aquasil™ presents an alternative surface treatment for applications where a high degree of repellence towards water and water-based soil is required, but without fluorocarbons or isocyanates.

An alternative to PFC in breathable membranes for textiles.

Arnitel® VT, produced by DSM, is a commercial product specifically designed to have a very high breathability which makes it an alternative to PFC based breathable membranes used in textile applications. Arnitel VT is a thermo plastic co-polyester; halogen and plasticizer free, free of fluor or fluor based components and 100% recyclable. Due to its nature, Arnitel VT also has a carbon footprint which is significantly lower than fluor (PFC) based products.
