ABSTRACT

As part of the current debate on the opportunities and risks of nanotechnological applications, the debate on possible contributions to sustainable development is becoming increasingly controversial. It should rather be conducted on a more objective level. This objectification, however, can only be achieved on a case-specific basis, performing-as quantitatively as possible-a risk-and-benefit assessment targeted toward the total life cycle. The methodological basis for such a systemic view, however, is still largely lacking. Against this background, the nano-sustainability check as a recently developed tool provides an instrument offering a systematic raster for an integrated approach relative to sustainability aspects of nanotechnological applications. With the help of this tool, companies that develop or produce nanotechnological products and applications can carry out a self-evaluation of their own business activities. Its most important feature is an evaluation raster of a total

of 14 key performance indicators by means of which nanoproducts (i.e. products that are produced with nanomaterials) can be analyzed by comparison with an existing reference product that has been manufactured without the use of nanomaterials. The results of the key performance indicators are depicted in a SWOT matrix that combines an inward-looking strength/weakness analysis with an opportunity/threats analysis that is related to external factors. Based on this matrix, recommendations for a strategic optimization of the investigated application can finally be developed. Their goal is to maximize the positive potential of strengths and opportunities with regard to sustainability while minimizing potential negative effects of weaknesses and risks.
