Spent Pot Lining: An Introduction Factsheet

Published in

2022

As part of the aluminium industry’s waste-not-want-not approach to circularity – the IAI has produced two waste perception factsheets on spent pot lining (SPL) and bauxite residue.

The Spent Pot Lining Factsheet explains how SPL is produced, its availability and its use – and is presented in a simple and clear format to help inform the intended audience about the importance and usage of this by-product. The Factsheet also provides more information about toxicity levels and cites various case studies of how companies successfully use SPL.

You can download the factsheet in English and Chinese.

An illustration shows spent pot lining from aluminum smelters being repurposed. A pot of molten material is highlighted, with text stating 40-50% of this lining is recycled for use in cement production, steel production, and mineral wool production.

Reference document on how to treat scrap flows in carbon footprint calculations for aluminium products

In 2022, the IAI published Guidelines on Transparency that state that when reporting the cradle-to-gate carbon footprint of products that contain scrap there should be full transparency on the methodology used for the carbon footprint calculation. This reference document, summarising three potential approaches, should serve aluminium producers to disclose the methodology they ...
