Title: Economic model for end of life management of printed circuit boards
Author: Rao, Nikhil Umesh
Abstract: The objective of this research is to develop an economic model for the recycling of printed circuit boards . The process of extraction of copper using traditional recycling methodology is considered . Both cost and energy models are develop for this process . The various factors affecting the costs are identified and the assumption of linearity between the individual costs and the total cost is validated using test of hypothesis . The costing methodology used is activity based costing . All the activities and cost centers are defined and the total cost is arrived at . The energy calculations are performed by analyzing the energy inputs that go into each process step . The energy computation is then made based on these energy inputs and the total energy is arrived at . The cost and energy models are validated by making use of a case study . Also , the energy estimate for new process of recycling like super critical fluids is computed based on the energy model developed . The economic model provides a framework where both cost and energy calculations can be performed and the process can be evaluated and improved upon .
