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: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

Im Focus: Hybrid optics bring color imaging using ultrathin metalenses into focus

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.

But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...

Im Focus: Stem cell divisions in the adult brain seen for the first time

Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.

The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
