Recycled steel should not be the only criterion for classifying steel tire reinforcements as sustainable. Reducing climate impact and materials consumption should be prioritized over the next decade. Many products have quality requirements more suited to using high recycled content and comprise more of the global steel market than steel tire reinforcement feedstocks. Pursuing higher recycled steel content in tires could shift steel mill recycled steel output to lower-productivity products and stifle the development of higher-strength steel grades that could lead to lower carbon emissions during the tire lifecycle.

What the audience will learn

• Recycled steel content is not the only measure of steel tire reinforcement sustainability
• Recycled content is dependent on the steel-making process
• Gains in material efficiency depend on high-quality feedstocks
• Steel operational life is typically 10-50 years after production, and available end-of-life scrap can lag behind steel demand by several decades
