A Computational Model For Electronic-Waste Dynamics

Abstract

This paper presents an overview of a research project focused on the development of computational models for studying the dynamics of Electronic waste. E-waste is becoming an issue of concern in developing countries in general and Nigeria in particular.  The e-waste problem is increasing in dimension due to two main reasons: (i) lower prices of electronics and computer hardware and peripherals and (ii) the progressive reduction in the usage lifespan of electronic equipment.  These result in the accessibility of electronic equipments to a greater number of people as well as in the increase in the rate at which the equipments become obsolete. This research is motivated by the need to developing a computational system for studying and predicting the pattern of e-waste accumulation.  The methodology to achieve this aim includes data collection, e-waste process characterization and the design of a computational model based on the Markovian Birth-death process.  Data from the Obafemi Awolowo University e-waste environment is used to develop the model.  Our model will be useful in supporting decisions about the technical and economic problems emerging as a result of rising demand, user population growth, short usage life span and a decline of suitable disposal mechanism for e-waste.
