The goal of the study is it to represent and evaluate the entire product life cycle of two potential future nanotechnological applications from raw material acquisition through production, use and disposal. In addition a comparison of nanotechnological applications with conventional applications is to be accomplished.

The following two applications were examined in coordination with the sponsor, the Nagano Techno Foundation, of Nagano City, Japan:

  • CNT composite material – Next Generation CNT composite material as carrier tray for electronics components,
  • CNT composite films – Electrodeposited nickel-CNT composite films for metal substrates, for example of wind power applications.
Therefore, the product life cycle of the investigated products has been documented in detail. Additionally, different assumptions have been made for the wastage of carrier trays or the size of composite films area, and some chemical synthesis and scenarios are produced for variable values like (energy) production efficiency. Thus, the environmental impacts of the different scenarios can be shown, compared and assessed.

In the study, the focus is placed on the potential environmental relief provided by potential future nanotechnological products based on the two several multiwalled carbon nanotubes Baytubes® and VGCF®.
