Ecotechnologies – A Major Route for DurableSustainable Development in the Metal Materials Industry

Abstract

The paper shows that the durable and sustainable development depends on the quality of the events occurring in the convergence area between the natural ecological system (N.E.S.) and the technological system (T.S.) represented by the metal materials industry. The analysis is carried out in the following situations:
- decrease in the level of negentropy (nS) of N.E.S., due to the consumption of natural resources by T.S., and
- increase in the level of entropy (S) of N.E.S., due to the discharge into the environment of the pollutants generated by T.S.
Ecotechnologies constitute a major tool for optimizing the correlations N.E.S.-T.S. Our study proposes a classification of ecotechnologies in four categories, according to their influence on nS and S. The role of ecotechnologies in reducing the environmental entropisation phenomenon is also highlighted.
