Abstract
Process design in the chemical industry is challenged to integrate env ironmental and safety aspects in addition to economic and technical co nsiderations in the early development phase of a new process. To achie ve this goal, a flexible assessment framework of ecological and econom ic indices presented in part 1 of this paper is applied to two industr ial case studies, one relying on purely chemical literature data and t he other including early process knowledge. An allocation method for w aste streams, components, and costs is presented and mass lass indices (MLI), cost indices (CI),and ecological indices (EI) are calculated. Using this index system, the ecological and economical problems of a p rocess can be identified at their roots. Hence, this method supports t he search for more cost-effective and environmentally friendlier chemi cal processes.
