Comprehensive Analysis of External Dependency in Terms of Material Criticality by Employing Total Material Requirement: Sulfuric Acid Production in Japan as a Case Study

摘要: Securing stable material supply is of paramount importance since materials are fundamental to the economy and human well-being. The domestic production consumption ratio has conventionally been utilized as a main index for external dependency in terms security its criticality. However, conventional approach confines application raw materials, which potentially risks reaching short-sighted conclusions policy-making process. Beyond analysis dependency, development more applicable every consider diversification comprehensively aid overall As such, this paper establishes new methodology analyzing related product by using concept total requirement (TMR). Applying methodology, sulfuric acid Japan evaluated case study. Previously unexamined elements associated with revealed comprehensive approach. may be use policymakers designing sophisticated well-grounded securement policy.
