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.

Key words: green processes, resource utilization, process integration, environmental economy, ecological industry
