Showing papers on "Green chemistry metrics published in 2001"
TL;DR: In this paper, an approach to quantitatively and systematically evaluate synthetic organic reactions and processes is described, which allows chemists to clearly assess whether or not chemistries and chemical processes are "greener".

TL;DR: A set of metrics has been developed which enables a simple assessment to be made of batch processes in terms of waste, energy usage, and chemistry efficiency as discussed by the authors, which is intended to raise awareness of green chemistry by providing a tool to assist chemists in monitoring progress in reducing environmental impact.

TL;DR: This paper compares the scientific implications, implementation framework, and relative performance of these metrics using various electronic products as case studies.
Abstract: Various performance metrics have been developed to evaluate quantitatively the environmental impact of products, processes and activities. Much attention has been given to developing a stronger scientific basis for comprehensive environmental performance metrics. Eco-indicator 95, Eco-indicator 99, ecological footprints, and EcoPro developed by Lucent Technologies in collaboration with MERC at NJIT, are four environmental performance metrics representing this group. This paper compares the scientific implications, implementation framework, and relative performance of these metrics using various electronic products as case studies. Since each metric is based on different methodological structures, weighting techniques, and assumptions, the absolute magnitude of the output cannot be compared; however, in the context of assessments for competing products with equivalent functionality, the final results can be examined on a relative basis.

TL;DR: In this paper, the background and connotation of green process engineering science is described and analyzed with actual examples of research, and discussion is made on methods, objectives, scopes and prospect of research on resource utilization-materials conversion processes based on the environmental economy assessment system.
Abstract: The background and connotation of the green process engineering science is described and analyzed with actual examples of research, and discussion is made on methods, objectives, scopes and prospect of research on resource utilization-materials conversion processes based on the environmental economy assessment system The research intentions in green process engineering are stated, including the cross-linking and incorporation of chemistry-physics-biology-computational information with environmental science, optimal integration of materials and energy flows, intensification and sequenced aggregation of reaction(separation, optimization of operation control and multi-scale theories, which are further refined as the optimal engineering scale-up theory for green process engineering in green industries It is expected that this theory could provide scientific and engineering criteria for green upgrading of process industries and new type of ecological industry in the 21st century
