Life cycle engineering methodology

Product Modification modification of product characteristics in order to minimize the environmental impacts of the product during or after its use (disposal) or to minimize the environmental impacts of its production. This implies the application of Life Cycle Engineering (Airing 1995 Hauschild et al. 2005) or eco-design (Brezet and Van Hemel 1997 Dewulf 2003 Wimmer et al. 2004) methodologies. 

The first step of the possible methodology is to identify the physical chemical properties the solvent mnst possess for a given application. A detailed engineering analysis of the application will yield many performance constraints. Constraints are also obtained considering the solvent s entire life cycle. 

This section presents two case studies demonstrating typical usage of the described RE methodologies and tools in different domains and applications. Based upon flie cases from Indesit Company and Volkswagen [48], the requirement life cycle is explained and it is shown how RE tools are integrated into the systems engineering concept.
