Emergy, spelled with an ‘M’, is the embodied energy contained in a product, a good or a service.
This work is intended for economic and academic stakeholders, who are conscious of implementing or disseminating technical solutions which fall within the scope of a particular development that demonstrates consideration for our planet’s limited resources.
In many cases, specific emergy is considered to be constant. Here, the author studies this concept in depth and introduces a specific emergy as a function of both the location and the time-pathway. This is done by focusing on the inherent assumptions (often untold) of the sources. A comparison between fossil fuels and renewable resources is then made. A significant part of the book addresses recycling and its associated concerns with the decline of raw (mineral) matter.
In addition, the concept of a CO2 footprint is quite well known, but this kind of assessment does not allow a comparison between raw matter and recycling; this book presents such an analysis.
This book will be useful for students at undergraduate and graduate levels, in the field of eco-design as well as engineers and researchers. It will also be of use to anyone who is concerned by the use of reserves (fossil fuels, non-fossil fuels and minerals) and the inherent political and social concerns that this entails.
