Description

Recycling of Polyurethane Foams introduces the main degradation/depolymerization processes and pathways of polyurethane foam materials, focusing on industrial case studies and academic reviews from recent research and development projects. The book can aid practitioners in understanding the basis of polymer degradation and its relationship with industrial processes, which can be of substantial value to industrial complexes the world over. The main pathways of polymer recycling via different routes and industrial schemes are detailed, covering all current techniques, including regrinding, rebinding, adhesive pressing and compression moulding of recovered PU materials that are then compared with depolymerization approaches.

The book examines life cycle assessment and cost analysis associated with polyurethane foams waste management, showing the potential of various techniques. This book will help academics and researchers identify and improve on current depolymerization processes, and it will help industry sustainability professionals choose the appropriate approach for their own waste management systems, thus minimizing the costs and environmental impact of their PU-based end products.

Key Features

  • Offers a comprehensive review of all polyurethane foam recycling processes, including both chemical and mechanical approaches
  • Assesses the potential of each recycling process
  • Helps industry-based practitioners decide which approach to take to minimize the cost and environmental impact of their end product
  • Enables academics and researchers to identify and improve upon current processes of degradation and depolymerization

Readership

Engineers and sustainability professionals in industries using polyurethane, including packaging, insulation, upholstery, bedding, apparel, and electronics; students, researchers, and scientists/faculty in the disciplines of Chemistry, Physics, Polymer Science, Materials Science, Chemical Engineering and Mechanical Engineering
