Table III Life cycle assessment results for microwave hot air systems...

In this study, the life cycle assessment of microwave hot air systems were developed using the analytic hierarchy process and the fuzzy comprehensive evaluation. The hierarchical structure consists of assessment aspect and assessment objective were established. The fuzzy assessment matrices of the assessment mathematical model were calculated using eigenvalue method and Gauss-Seidel iterative matrix. The life cycle assessment results show that the microwave hot air systems have a good green degree. 

The preceding operational description indicates that fuel choice radically affects the required daily maintenance, overhaul, time between overhauls, and therefore effective life cycles of components. Undoubtedly, fuel choice can radically affect life-cycle assessment results. 

FIGURE 16.1 Comparison of life cycle assessment and life cycle cost calculations. The result of LCA is (weighted) emissions and the present value of investment and operating costs, e.g,. in Euros. Note that in LCA calculations the present value coefficient is I, but the present value of LCC is always affected by interest rate and the length of the period. ...

On the other hand, in part II of this volume, a set of case studies are introduced. The application of the selected methodologies inside each one of the foresaid disciplines (e.g., risk assessment, life cycle assessment) to specific cases and countries is presented here. The results of such application are discussed as well as their reliability. Toxicological studies in Italy, risk assessment of electronic waste in China, or disposal of bearing lamps in India are some examples of selected scenarios.

In the previous chapters, thermodynamic analysis is used to improve processes. However, as pointed out in Chapter 9 (Energy Conversion), the exergy analysis did not make any distinction between the combustion of coal and natural gas and, as a result, could not make any statements regarding toxicity or environmental impact of exploration, production and use of the two fuels. A technique that can do this is LCA. What exactly is life cycle analysis In ISO 14040 [1], life cycle analysis (or life cycle assessment) is defined as "the compilation and evaluation of the inputs, outputs and potential environmental impacts of a product throughout its life cycle."...

The inventory data and the classified and characterized results are the ecological profile of the product or product system under study. These profiles may be used as modules for the life cycle assessment of subsequent products, for which these products are input of goods (e.g. LCl data of a steel production analysis are the basis for an LCA of a car made of tailored blanks such as building material profiles, for example, may be used to analyze buildings). A prerequisite for this is however that the methods and background data used for the modeling of the systems are identical.
