Industrial ecology is the means by which humanity can deliberately and rationally
approach and maintain a desirable carrying capacity, when given continued eco-
nomic, cultural and technological evolution. The concept requires that an indus-
trial system be viewed not in isolation from its surrounding systems, but in concert
with them. It is a system's view in which one seeks to optimize the total materials
cycle, from virgin material to finished material, to component, to product, to obso-
lete product, and to ultimate disposal. Factors to be optimized include resources,
energy, and capital

.
Many believe that implementing industrial ecology will be a principle challenge
for business and society in the twenty-first century. The race is to become the most
innovative, most visionary, and most effective company understanding industrial
ecology, and implementing designs for the environment.
With all of the above discussed aspects in mind, Yoshimura proposed a new
concept of materials processing, namely soft solution processing, which meets all
the demands of materials processing in the twenty-first century. This soft solution
processing for high performance inorganic materials is fast catching on with mate-
rials scientists worldwide, because it deals with low energy processing using solu-
tions which minimize environmental impact (sometimes called chimie douce), it
will be the key to environmental improvement. Temperature for preparation will
