      Dear colleagues,

      Environmental gains derived from the use of
      nanomaterials may be offset in part by the
      process used to manufacture them, according to
      research published in a special issue of the Journal of Industrial Ecology.

      The
      <http://www.blackwellpublishing.com/jie>Journal
      of Industrial Ecology is a peer-reviewed
      bimonthly owned by Yale University, headquartered
      at the Yale School of Forestry & Environmental
      Studies and published by Wiley-Blackwell.

      The special issue is available for free download
      at <www.interscience.wiley.com/journal/jie-nano>.

      Special Issue of J. of Industrial Ecology:
      Nanomaterials May Have Large Environmental Footprint

      According to a paper by Hatice Sengül and
      colleagues at the University of Illinois at
      Chicago, strict material purity requirements,
      lower tolerances for defects and lower yields of
      manufacturing processes may lead to greater
      environmental burdens than those associated with
      conventional manufacturing. In a study of carbon
      nanofiber production, Vikas Khanna and colleagues
      at The Ohio State University found, for example,
      that the life cycle environmental impacts may be
      as much as 100 times greater per unit of weight
      than those of traditional materials, potentially
      offsetting some of the environmental benefits of
      the small size of nanomaterials.

      Materials engineered at dimensions of 1 to 100
      nanometers (1 to 100 billionths of a meter)
      exhibit novel physical, chemical and biological
      characteristics, opening possibilities for
      stunning innovations in medicine, manufacturing
      and a host of other sectors of the economy.
      Because small quantities of nanomaterials can
      accomplish the tasks of much larger amounts of
      conventional materials, the expectation has been
      that nanomaterials will lower energy and resource
      use and the pollution that accompanies them. The
      possibility of constructing miniature devices
      atom-by-atom has also given rise to expectations
      that precision in nanomanufacturing will lead to
      less waste and cleaner processes. Research
      described in this special issue suggests that
      these anticipated benefits remain to be realized.

      Other topics explored in the special issue include:
      * Approaches for identifying and reducing the
      life cycle hazards of nanomaterials
      * Quantified life cycle energy requirements
      and environmental impacts from nanomaterials
      * Tradeoffs between nanomanufacturing costs
      and occupational exposure to nanoparticles
      * Efficiency of techniques for nanomaterials synthesis
      * Improvement of the sustainability of
      bio-based products through nanotechnology
      * Industrial frameworks for responsible nanotechnology
      * Industrial and public perception about the
      risks and benefits of nanomaterials
      * Governance and regulation of nanotechnology
      Industrial ecology is a field that examines the
      opportunities for sustainable production and
      consumption, emphasizing the importance of a
      systems view of environmental threats and remedies.
