Mechanical Recycling Landscape

This document explores the role, processes, and challenges of mechanical recycling. It examines the types of feedstock used, comparative advantages over chemical recycling, and key players in the market. Innovation opportunities and the broader impact of mechanical recycling on sustainability and circularity are also highlighted.

Last updated: 16/07/2024

Introduction & Key Terms

  • Waste Valorisation: Large volumes of post-industrial and post-consumer textile waste are generated annually, with the potential to be recycled into new fibres.
  • Resource Efficiency: Virgin material production has significant environmental consequences, making recycling a crucial alternative.
  • Driving Circularity: The current textile recycling rate is low, necessitating greater diversion to circular end-use destinations.
  • Mechanical vs. Chemical Recycling: Mechanical recycling involves physical processes like shredding, whereas chemical recycling uses solvents or catalysts.
  • Challenges: Shorter fibre length, high purity feedstock requirements, and cost challenges limit the scalability of mechanical recycling
  • Innovation Needs: Advancements in fibre opening, blending techniques, and contamination removal are essential for improving output quality.
