Sustainable Steel Materials

For manufacturers and builders committed to sustainability, sourcing environmentally responsible steel poses challenges. This article provides guidance on procuring and specifying more sustainable steel materials that minimize environmental impacts.

Specify Recycled Content

Seeking steel made from recycled scrap reduces the demand for virgin iron ore mining. Most structural and sheet steel today contains 25-95% recycled content. Maximizing post-consumer recycled steel supports the circular economy.

Source Locally

Choosing steel suppliers located closer to operations cuts transportation miles resulting in lower carbon emissions. Local sourcing also ensures responsiveness and just-in-time delivery. Domestic mills and distributors may offer more sustainable options.

Seek Green Certifications

Certain respected certifications like Cradle to Cradle and GreenCircle validate sustainability initiatives by steel manufacturers. Specifying certified sustainable steel ensures responsible upstream processes.

Require Responsible Practices

Require suppliers provide evidence of ethical mining, rigorous environmental management, water conservation, worker safety, and transparent sustainability reporting. Favor progressive providers.

Consider Alternate Materials

In suitable applications, alternate sustainable materials like bamboo or recycled plastics may serve structural needs with lower impacts than virgin steel. Material substitution assessments help identify greener options.

Favor Energy-Efficient Mills

The amount of energy required during steelmaking has major environmental consequences. Seek suppliers actively investing in energy efficiency upgrades, renewable power, and emissions-reduction initiatives.

Minimize Processing

The more production and finishing steps required, the greater the lifetime environmental impact. Simplifying part geometries and limiting processing/coating supports dematerialization efforts.

Enable Recyclability

Designing products using monolithic steel grades, no toxic coatings, and avoiding co-mingled materials simplifies end-of-life recycling to close the loop.

Adopt Circular Business Models

Consider circular services like steel reuse, refurbishment, repair, and takeback to retain more value and extend asset lifetimes rather than constantly extracting new materials.

Making sustainably-minded decisions when sourcing steel materials demonstrates your organization’s commitment to supply chain responsibility. Let us know if you need further guidance on green procurement strategies.
