This research project aims to assess the components parts of a PC to determine which
parts contribute most adverse to environmental impacts, and to make recommendations
about the potential for recycling and recovery of materials at the end-of-life of a PC. The
investigation is performed by implementing LCA methodology on the PC. This paper
summarizes the methodology generated. A PC used is the Pentium IV ABA PC including
the Compaq monitor, keyboard and mouse. The procedure of the LCA follows the ISO
14040 series. System boundary includes the entire life cycle of the product, including raw
material acquisition, material processing, transportation, use and disposal. The LCI and
impact database for a PC is constructed using SimaPro software version 6.0 after
disassembling the PC and taking an inventory of its component parts.
