Advanced rubber and plastic recycling from theory to industrial scale

Scaling polymer recycling from laboratory research to industrial production demands integrated knowledge of rubber and plastic processing, devulcanization chemistry, and separation science. Polymer Recycling and Waste Management delivers that integration, spanning theoretical principles, experimental findings, and large-scale production methods alongside sustainability frameworks and circular economy models relevant to both academic research and commercial operations.

The book covers advanced devulcanization techniques, bio-based reclamation, and microplastics mitigation strategies supported by over 100 figures, diagrams, and flowcharts. Detailed case studies and experimental data address real-world challenges facing tire manufacturers, rubber recyclers, and polymer processing firms. Chapters extend from mechanical and chemical recycling fundamentals through energy recovery methods to policy frameworks guiding global waste management regulation.

Readers will also find:

  • Practical process flow diagrams and industrial insights for scaling cost-effective polymer recycling from bench to production
  • Coverage of bio-based reclamation technologies and green degradation approaches shaping next-generation sustainable materials development
  • Detailed examination of separation techniques applicable to mixed polymer waste streams in commercial recycling operations
  • Analysis of circular economy models and regulatory frameworks informing environmental policy decisions across multiple industries
  • Experimental data and case studies connecting devulcanization chemistry with scalable rubber and elastomer recycling processes

Designed for researchers, advanced students, and R&D professionals in polymer science, chemical engineering, and environmental engineering, this reference connects recycling theory with industrial practice. Policy advisors involved in environmental regulation and circular economy initiatives will also find directly applicable frameworks and data.
