The concept of a circular economy has been gaining increasing attention in recent years. Many of the sources of chemicals we have become reliant on are dwindling and the accumulation of waste products poses a serious environmental problem. By recovering resources from these waste materials, we can reduce our dependence on virgin feedstocks that may not be sustainable as well as reducing the quantity of material going to landfill sites.
Incorporating different perspectives from a global authorship, this book aims to introduce systems thinking to the field of waste and resource management. The topics covered range from the use of biogeochemical processes in resource recovery to the application of engineered nanomaterials, with information relevant to both academia and industry.
The broad range and cross-disciplinary nature of the topics in this book make it a valuable resource for those working in circular economy research, green chemistry and waste and resource management.
