Recycled Cotton and Circular Economy
topic
Recycled cotton is recovered from pre-consumer cutting waste (20–25% of fabric in garment manufacturing) and post-consumer textile waste via mechanical shredding (garnetting at 800–1,200 rpm) producing recycled fibre with length 8–18 mm (versus 25–35 mm virgin), strength 15–22 g/tex (versus 28–34 g/tex), and 60–80% higher short fibre content. Blending with 30–50% virgin cotton or polyester is required for ring spinning at Ne 10–20; open-end rotor spinning accepts up to 70% recycled content at Ne 6–16. Carbon footprint of recycled cotton is 0.5–1.5 kg CO₂e/kg versus 5.5–8.0 for virgin cotton — 75–90% reduction. Water consumption is 300–500 L/kg recycled cotton versus 10,000 L/kg virgin. EU Strategy for Sustainable and Circular Textiles (2022) mandates EPR (Extended Producer Responsibility) for textiles by 2025, targeting 25% recycled fibre content in textile products by 2030. Re:newcell, Renewlane, and Evrnu have developed chemical recycling routes restoring virgin-equivalent fibre properties.
Role
Central to achieving circular economy targets for the textile industry, enabling 75–90% reduction in carbon and water footprint versus virgin cotton production while diverting post-consumer textile waste from landfill into regenerative fibre supply chains.
