Abstract

Our planets resources are being consumed at an extremely unsustainable rate. Renewable resources are being used up before they can replenish themselves, and non-renewable resources are depleting fast. In our current situation, it is not enough to merely recycle materials. Usually, by the time a product is manufactured, the damage is already done by overuse of materials, the use of non-sustainable materials and processes, and also by materials and processes that pollute the environment. Life cycle assessment is the 'cradle to grave' analysis of a product, in order to identify the sources of excessive material consumption, and also manufacturing processes that cause pollution. Through the results of an LCA analysis, it is then possible to make decisions and improvements to current designs and processes. In the field of electronics, for example, the manufacture of Printed Circuit Boards can cause water and air pollution if not done properly. However, through Life Cycle equivalent studies, standards have now been developed for the proper and sustainable development of printed circuit boards. The same applies to many other electronic components and devices. In this research project, all preceding work and studies on the subject matter has been covered. The current methodology for an LCA study has been covered from an International Standards Organization requirement standpoint. Finally, a suitable electronic product, a Calculator has been chosen for this study due to its similarity in terms of main components (Plastic outer casing, printed circuit board, smaller electronic components, rubber keypad, glass screen, and a battery). From this, the methodology was implemented in the chosen LCA software (SimaPro v5.1), and Impact assessments were performed on the Calculator based on selected Impact assessment methodologies, then thorough sensitivity analysis was performed in order to check the validity and to justify all choices for data (materials and processes as well as disposal procedures). Finally, Improvement assessments have been made, for ease of comparison with other similar products. Any ideas for future work that have occurred during this project have been presented in the final chapter.
