This paper summarises the main elements, the methodological developments of LCA, and the steps of the assessment (defining the goal and scope of study, life cycle inventory, life cycle impact assessment and interpretation of the study). It describes the weighting process as the base of assessment, and the different applications of LCA. It also presents a case study for polystyrene and biopolymer packaging, in which investigates the environmental and economic results of comparative LCA - between LCA of PS and Biopolymer. LCA is a decision support tool. It can help to ensure the environmentally sound practices, from a financial aspect it means a new approach to process optimisation. The assessment has been supported by software aids to determine the benefits, the weaknesses, and the IO —LCA shows the economic benefit of the process. |
