A major mining company successfully transitioned from conventional polyester and cotton uniforms to 100% recycled industrial fabrics, reducing textile waste, lowering carbon emissions, and achieving measurable total cost of ownership benefits. Key success factors included certified recycled materials (GRS), durability validation under abrasive mining conditions, worker comfort testing, supplier audits, and a phased implementation across sites.

1. Introduction

Mining operations are among the world’s most demanding industrial environments. Workers are exposed to:

• Abrasive surfaces
• Heat and dust
• Heavy equipment
• Chemical hazards
• Prolonged shifts in extreme conditions

These realities traditionally drive companies to use high-performance virgin polyester and cotton blends, designed to withstand mechanical damage and chemical exposure.

However, growing environmental commitments, investor ESG pressure, and the availability of recycled industrial-grade textiles have pushed some forward-thinking mining companies to explore sustainable uniform solutions—without compromising performance.

This case study details how Global MinTech Industries (GMI) (a global mid-tier mining group with 14,000 workers) became the first mining firm in their region to adopt 100% recycled fabrics for all workwear, achieving major sustainability and financial gains while maintaining compliance with ISO, EN, and local PPE safety standards.

2. Why Mining Companies Are Moving Toward Recycled Textiles

2.1 ESG and Shareholder Pressure

Mining companies face intense scrutiny from investors, regulatory bodies, and financial markets. Uniform procurement, though small compared to heavy equipment spending, is a visible and measurable ESG impact category.

Typical ESG Targets Influencing Apparel Procurement

• Reduction of Scope 3 emissions
• Lower water consumption
• Circular lifecycle adoption
• Better waste management metrics
• Supporting local or certified green supply chains

Switching to recycled fabrics directly improves several ESG audit indicators.
