Certain metals such as steel,aluminium follow sustainable methods but some does not.
Explanation:
Metal production means conversion of a raw material, such as a metallic ore, to a final form which can be used for some commercial or industrial purpose. In some cases, metal production gives few steps since the metal already occurs in an elemental form in nature.
Sustainable manufacturing is the creation of manufactured products through economic processes that minimize negative environmental impacts while conserving energy and natural resources.
Steel is a uniquely sustainable material because Steel is truly recyclable and is truly recycled.
Aluminum poses no danger of environmental toxicity therefore, secondary aluminum production from recycling scrap has the potential to significantly reduce greenhouse gas emissions.
But some metals production does not follow subsequent methods.
