Outline of Final Research Achievements

Sustainable resource management needs a monitoring system of international trade on metal resources using the UN comtrade that provides trade statistics collected by each country. This study explored to estimate the inter-country flows for metal ores and scraps considering the uncertainty with the inter-country trades from the UN comtrade and with the metal composition. This study assessed the uncertainty of the inter-country flows of major metal ores and scraps that are available from the UN comtrade by using Intraclass Correlation Coefficients. The meta analysis based on systematical literature review was conducted to assess the uncertainty with the composition of major metal ores and scraps. This study estimated the inter-country flows of major metal ores and scraps by modifying the both uncertainty mentioned before.
