New challenge for producers of refrigerators

26.11.2003


The European Union has introduced a directive on waste electrical and electronic equipment (WEEE). The directive makes producers responsible for the recycling of the electrical and electronic equipment that they put on the market. The results from a study of refrigerators made by CIT Elektronik, Chalmers Industriteknik in Sweden, indicate that the targets of the WEEE directive can not be achieved with the ordinary shredders used today. The study is based on the situation in Sweden, but it will be much the same in other European countries.



CIT Ekologik AB has on commission of Stiftelsen Svenskt Kretslopp, and in cooperation with Electrolux Home Products Operations AB, carried out a comparative cost benefit analysis of recycling electrical and electronic equipment. The main objective of this study has been to assess and compare the environmental and economic performance of recycling of two similar electrical or electronic products, in order to enhance the knowledge of the costs for recycling.

The production of electrical and electronic products is one of the most rapid growing domains of manufacturing industry in the western world today. The rapid growth of consumption of electrical and electronic products increases the generation of waste as well. In January 2003, the European Union introduced a directive on waste electrical and electronic equipment (WEEE). The directive makes producers responsible for the recycling of the electrical and electronic equipment that they put on the market. By 2006 producers will have to meet recycling and recovery targets mandated by this directive.


In the study two similar products have been analysed in order to:
• compare the economic costs for the recycling of the products,
• study if there are any environmental differences when recycling the products.

The study comprises an environmental analysis based on life cycle assessment (LCA), economic analysis, and a cost benefit analysis. Two types of refrigerators, containing the cooling agents hydrofluorocarbons (HFC) and hydrocarbons (HC) respectively, have been studied. The refrigerators are assumed to be collected from the Swedish households and to be recycled in Sweden. The results of this study show i.a.:
  • that the targets of the WEEE directive for material recycling of refrigerators will not be achieved if the ordinary shredders of today are used,

  • that glass, plastics, and PURfoam (polyuretan foam) must be recycled to a greater extent than today. One problem is that there are difficulties in recycling PURfoam and a lack of use of recovered foam toda,.

  • that the targets of the WEEE directive for material recycling of refrigerators can be achieved if the refrigerator shredders of today are complemented with additional technology,

  • that the targets of the WEEE directive for material recycling of refrigerators decrease the environmental load and the environmental costs, but increase the business economic costs.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
