About the book
In linear economy, petrochemical materials are frequently used as monomers to produce polymers that are usually disposed after their final applications. In circular economy, all waste materials after their use are reprocessed in order to form new raw materials, closing all cycles. Recycling of polymers is one part of the solution needed to create a circular economy for plastics. Recently, the development of biodegradable polymers has not solved the problem since the degradation in Earth’s landfills does not lead to the recovery of materials, while degradation in oceans possibly creates new unintended environmental problems. Thus, the development of sophisticated chemical recycling techniques or chemically recyclable polymers is the most sustainable solution to establish a circular materials economy.
This book aims to present the state-of-the-art for recycling methods of polymeric materials integrated into the field of the circular economy, as well as introduce various methods of (mainly) chemical recycling of plastics, aiming at the recovery of raw materials (monomers), other secondary value-added products, or bio-fuels. Additionally, presentation of highlights and technical and environmental benefits obtained from the development of the emerging area of recyclable polymers are welcome. Methods for the potential recycling of bio-based plastics, used lately in combination with conventional polymers, also fall within the scope of this project.
Finally, the aim of the book is to present methods for the recycling of polymers from two very interesting waste streams, i.e. those of waste electric and electronic equipment, and plastic packaging. Problems associated with the existence of possibly harmful additives in these plastic applications and their successful recycling are encouraged to be noted.
