Abstract
For the study of desirable Sound Material-cycle (SMC) Blocks, it is necessary to construct an optimal scale for the characteristics of regional and recyclable resources. This study assumed that SMC blocks are dictated by generation density, transportation efficiency and scale factors of intermediate waste processing. The constructed model set up governing parameters for three parameters. This paper analyzes the causal linkage between governing parameters and SMC blocks using sensibility analysis and case studies. When substance specific parameters and actual urban data are applied to the theoretical model, it can calculate SMC blocks and provide a comparison of the characteristics of items and regions.
