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. The authors cover all current techniques, including regrinding, rebinding, adhesive pressing and compression moulding of recovered PU materials and then compare these with depolymerization approaches.

Polyurethane Foam (PUF) has a diverse range of applications and is ubiquitous in packaging, but this results in a large amount of waste, which requires disposal (landfill, incineration, or recycling). They have a high calorific value due to their crude oil origin, which, if utilized, can be integrated into the production cycle of many chemical and petrochemical industries, boosting production and reducing the environmental burdens associated with plastic waste articles accumulation.

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, minimizing the costs and environmental impact of their PU-based end products.
