The Principles of Resource E
ciency
16.1 Introduction
Throughout the length and breadth of this topic, the reader has seen that material
savings imply energy and water savings which then results in the direct and indirect
optimisation of resources. The reader has also been introduced to Thermodynamics
and how through its laws and exergy derived concepts, material flows and degra-
dation states can be measured. Consequently, a general theory applied to exergy
savings is simultaneously one of energy, material and water minimisation, as first
discussed by the authors in Valero et al. (1986) and later in Lozano and Valero
(1993).
This chapter explains the Principles of Resource E
ciency, which the au-
thors have developed based on their energy and raw-material research undertaken
throughout the last two decades.
In this respect, it should be stated that a general theory does not allow for the
understanding of the principle behind the practice nor the guidelines which govern
material conservation. Whilst it is true that many have proposed solutions regarding
material savings and recycling, focusing on those actions that policymakers and
engineers can promote within their respective worlds, such solutions have not been
su
cient. Indeed there must be an underlying societal attitude towards resource
e
ciency if things are really going to change. It can never be a question of leaving
sole researchers to try and make a difference. Experts and laypeople alike must
be guided within the boundaries of science and a code of ethical practice which
converts good ideas into physical technologies and political frameworks that can
bring energy savings and sustainability to members of all social strata.
16.2 The necessity for a rational management of resources
For the development of any inclusive sustainable society, a rational management of
resources, whether biotic or abiotic, is required to ensure that everyone rightfully
obtains a dignified standard of living. Yet this ultimately means additional resource
