Cobalt is a vital element in many technological applications, which, together with its increasing end-use in batteries, makes it important to quantify its cycle of use. We have done so for the planet as a whole and for the three principal cobalt-using countries - China, Japan, and the United States - for 2005. Together, China, Japan, and the United States accounted for approximately 65% of the cobalt fabricated and manufactured into end-use products (a total of 37 Gg Co). A time residence model…

Integrated Modelling of the Global Cobalt Extraction, Supply, Price and Depletion of Extractable Resources Using the WORLD6 Model

The global cobalt cycle in society was modelled using an integrated systems dynamics model, WORLD6, integrating several earlier system dynamics models developed by the authors. The COBALT sub-model

The significance of Li-ion batteries in electric vehicle life-cycle energy and emissions and recycling's role in its reduction

Three key questions have driven recent discussions of the energy and environmental impacts of automotive lithium-ion batteries. We address each of them, beginning with whether the energy intensity of



Illuminating tungsten's life cycle in the United States: 1975-2000.

Tungsten is an example of a critical mineral resource where the majority of the United States' supply comes from imports, it has vital uses in manufacturing, and it has a high rate of loss at end-of-life.

The materials flow of cobalt in the United States

An initial evaluation of the flow of cobalt-containing materials in the United States was prepared. The following aspects of materials flow were included: cobalt released as a result of mining and

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.
