A Review of Life Cycle Assessment
As the pressures on the chemical and process industries to improve their environmental performance are increasing, the need to move away from narrow system definitions and concepts in environmental system management is becoming more apparent. Life Cycle Assessment (LCA) is gaining wider acceptance as a method that enables quantification of environmental interventions and evaluation of the improvement options throughout the life cycle of a process, product or activity. The main purpose of an LCA is to provide a quantitative assessment of the environmental impact of products over their entire life cycle, with a view to making improvements. Applications of LCA are key parts of the life cycle. This paper reviews some of the newly emerging applications of LCA. Reference is made to some important techniques for environmental assessment which interface with LCA. The essential features of the LCA methodology are reviewed and some specific difficulties in the application of LCA are identified and discussed. These difficulties include allocation of impacts to multiple products, the definition of system boundaries, the quality of data, temporal and spatial characteristics, and impact assessment methods.
