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.

Different ways to reduce the amount of halogenated flame retardants in electronics.

This document relates a study of how different corporations such as Apple, Sony Ericsson and Seagate have proceeded with eliminating PVC and halogenated flame retardants from their products. A few examples from the study will be described in this case story.

An alternative to PVC in wires and cables. A kind of plastic completely free from halogens, BFR´s (brominated flame retardants), PVC and plasticizers.

Arnitel® XG, produced by DSM, is an engineering plastic completely free of halogens, BFR´s (brominated flame retardants), PVC and plasticizers. The applications of the plastic are primarily in wires and cables intended for use in consumer electronics. Although the plastic is free from brominated flame retardants it still possesses good flame retardancy, as well as chemical and temperature resistance. These properties make Arnitel XG a possible alternative to PVC in wires and cables.

Eine Alternative zu PVC in Leitungen und Kabeln. Eine Kunststoffart ohne Halogene, bromierte Flammschutzmitteln, PVC und Weichmacher.

Arnitel® XG, hergestellt von DSM, ist ein technischer Kunststoff, frei von Halogenen, bromierten Flammhemmern, PVC und Weichmachern. Die Anwendungsmöglichkeiten des Kunststoffes liegen in erster Linie bei Leitungen und Kabeln für elektronische Verbraucherartikel. Obwohl der Kunststoff frei von bromierten Flammhemmern ist, besitzt es doch gute flammhemmende Eigenschaften, sowie Chemikalien- und Temperaturbeständigkeit. Diese Eigenschaften machen Arnitel XG zu einer möglichen Alternative zu PVC in Leitungen und Kabeln.

Polyvinyl chloride (PVC) Power Cord Alternatives

Polyvinyl chloride (PVC) has been targeted for replacement in electronic products because of concerns about the environmental and human health impacts associated with the disposal of PVC wires and cables. Thermoplastic elastomers (TPEs) are a class of potential alternatives to PVC. TPEs are inherently flexible, which can eliminate the need for phthalate plasticisers; however, they require an added flame retardant to meet regulatory requirements. To ensure that the replacements for PVC have a lower adverse impact to human health and the environment, potential replacement materials were evaluated using an integrated approach that incorporates a comparative chemical hazard screening step based on the GreenScreen for Safer Chemicals [http://www.cleanproduction.org/greenscreen.php], a framework developed by the non-governmental organisation Clean Production Action.

Proaktive Beschränkung von Quecksilber (Hg) in allen neu entwickelten Dell Notebooks und Bildschirmen

Quecksilber wird in der Hintergrundbeleuchtung von Flüssigkristall-Displays (LCD) für Notebooks und Flachbildschirmen (Monitoren) verwendet. Leuchtdioden (LED) wurden vor ein paar Jahren als Substitut für LCD-Hintergrundbeleuchtung eingeführt. Diese Technologie vermeidet die Verwendung von Quecksilber und ist energie-effizienter als LCD. Dell verwendet quecksilberfreie LEDs in Notebooks und Flachbildschirmen seit 2008. Für 2012 hat sich Dell verpflichtet, bei allen neu entwickelten Notebooks und Flachbildschirmen vollständig zur LED-Technologie überzugehen.

Proactive restriction of Mercury (Hg) on all newly designed Dell notebooks and displays

Mercury is used in Liquid Crystal Display (LCD) backlights of notebook and flat panel displays (monitors). Light Emitting Diodes (LED) were introduced as a substitute to LCD backlights a few years ago. This technology avoids the use of mercury while using energy more efficiently than LCD. Dell has been adopting the use of mercury free LED in notebooks and flat panel displays since 2008. In 2012, Dell is committed to fully transition to LED technology for all newly designed notebooks and flat panel displays.

Cleaning of wafer frames with brushing machines using tap water

Manufacturer of electronic components cleaned wafer frames made of fibre glass plastic using a continuous flow brushing machine with tap water. Formerly, components were cleaned manually with solvents.

Technology adaptation for arsenic free glass

Arsenic is used in special glass production to eliminate air bubbles that may lower quality in applications like electronics (TVs, cell phones, computers etc), for example. An alternative technology that maintains glass at high temperature for longer periods allows for bubbles elimination, without the need of arsenic containing additives.

Substitution von Borsäure durch Milchsäure als Biozid in Kühlschmierstoffen

Borsäure ist als reproduktionstoxischer Stoff der Kategorie EU 1B sowie als endokrin wirksamer Stoff eingestuft. Sie kann mit guten Ergebnissen durch Milchsäure substituiert werden, um das Wachstum von Bakterien und Pilzen in wassermischbaren Kühlschmierstoffen zu bekämpfen.

Substitution of boric acid by lactic acid as biocide in cooling lubricants

Boric acid is classified toxic for reproduction EU 1B and endocrine disruptor. It can be substituted by lactic acid with good results in keeping bacteria and fungi under control in water mixable cooling lubricants.
