Mass efficiency as metric for the effectiveness of
Abstract
Marco Eissen* and Konrad Hungerbühler from the Swiss Federal Institute of Technology in Switzerland, and Stefan Dirks and Jürgen Metzger from the Universitat Oldenburg in Germanyargue that metrics such as mass intensity, environmental factor and cost index indicate weak points with respect to environmental impact and cost efficiency in synthesis design. These weak points give a precise picture of the progress being made with alternative catalytic systems, and show how, for example, a switching to a heterogeneous system can affect efficiency, both positively and negatively
