With increasing international trade of secondary materials it is imperative to start including it in our analysis of recycling systems. The goal of this work is to set a materials-flow based foundation to do so. We provide a method for calculating the flow of scrap1 materials through an interconnected network of international trade. All analysis is presented through the specific example of copper scrap collected in USA, Germany, and Japan, which are leading generators of copper scrap. Results…

Material cycles in Asia: especially the recycling loop between Japan and China

In this article, we clarify the current status of Japanese exports and Chinese imports of secondary resources. A total of around 10 million metric tons (t) of secondary resources are exported

Secondary materials transfer from Japan to China: destination analysis

China has been the largest importer of secondary materials for recycling from Japan during the past decade. In this study, we analyzed the transfer of major secondary materials (plastic, steel,

Application of Markov Chain Model to Calculate the Average Number of Times of Use of a Material in Society. An Allocation Methodology for Open-Loop Recycling. Part 1: Methodology Development (7 pp)

Abstract-Preamble. In this series of two papers, a methodology to calculate the average number of times a material is used in a society from cradle to grave is presented and applied to allocation of

Multilevel cycle of anthropogenic copper.

A comprehensive contemporary cycle for stocks and flows of copper is characterized and presented, incorporating information on extraction, processing, fabrication and manufacturing, use, discard, recycling, final disposal, and dissipation, providing a framework for similar studies of other anthropogenic resource cycles.
