ABSTRACT
The life cycle assessment (LCA) is one of the potential tools of sustainable manufacturing. It enables the determination of environmental impacts across life cycle phases. The four phases of LCA are: goal and scope definition; life cycle inventory analysis; impact assessment; and interpretation. In phase I, the objective is mentioned along with its boundary conditions. Phase II includes collecting data for performing analysis. The life cycle inventory stage involves collecting and quantifying all the input and output data for a product in its complete life cycle. The impact assessment phase assesses the quantum of environmental impacts generated during the life cycle phases being considered. In phase IV, the results are analyzed to check the consistency with the goal and scope definition. It helps in ensuring completeness of the study. The procedures of life cycle costing with the computations are presented. The scenarios of manufacturing a new component and reverse manufacturing an old component are discussed.
