Abstract Scope |
Even though demand of cathode blocks constitutes only ~5 kg/tAl produced, the production of carbon and especially graphite cathodes is energy intensive. It is therefore essential to evaluate the carbon footprint of such products. In this paper, we focus on the complete Life Cycle Assessment of graphitized cathode blocks from “cradle-to-gate” based on our French operation.
The main production steps accounting for the majority of greenhouse gas emissions are coke calcination, block baking and graphitization treatment. Major sources of greenhouse gases are energy consumption and volatile combustion during heat treatment. Actual emission values as well as process optimizations and electricity grid mix influences will be discussed in the objective of achieving a greener Aluminum production. |
