Integration of environmental aspects and taking into account all aspects of sustainable development is one of the new trends in supply chain management (sustainable supply network). In this paper a new method, which is a comprehensive approach to determining the sustainable supply chain from raw material acquisition to the end of life is presented. Applications of the exergy concept in the field of sustainability is shown. The paper presents exergy as useful tool to measure sustainable supply chain. Exergy analysis can be used to identify problem areas in supply chain and inefficient uses of natural resources and design the supply chains for new products in multi-criteria decision making. Several methods taking into account the exergy analysis of any resource of a supply chain for sustainability performance measurement in whole life cycle was proposed.
Key word: Sustainable Supply Chain, Life Cycle Assessment, Exergy Analysis
1. INTRODUCTION
There are many methods taking into account the exergy analysis of any resource of a supply chain for sustainability performance measurement. They include: Extended Exergy
Accounting (EEA), Cumulative Exergy Consumption (CExC), Exergetic Life Cycle Analysis (ELCA) and Life Cycle Exergy Assessment (LCEA). The relationship between sustainable development, sustainable supply chain and use of resources, fuel, food, soil, water is very important. The Sustainable Supply Chain extends the supply chain by considering the backward flow (reverse supply chain) and the environmental, economic and social aspects.
According to the sustainable development principles non-renewable resource depletion should be minimize. Exergy analysis can be used to assess the depletion of these resources in supply chain. (...)
