The purpose of this paper is to construct an approach and a methodology to estimate future outflows of electronic waste (e-waste) in Gaborone City and most importantly tertiary education and financial service institutions to estimate future trends in the generation of obsolete computers. Accordingly, the study utilizes Stanford Method proposed by IMS 1991. The method estimates future e-waste generation quantities by modeling their proportional lifespan and variation in the distribution of lifecycle and percentage usage. The present work considers the approximation of e-waste generation based on variance in the distribution of product life span, in the absence of reliable information on actual WEEE arising. By making prediction, this helps to make informed decisions to plan and develop strategies for collection, storage, treatment, disposal and recycling services in order to channel computer waste through environmentally sound waste management system to prevent environmental and public health impacts. There is a need to enhance the limited existing collection of statistics regarding WEEE at landfills. The result shows that computer waste during 2009–2020 is increasing sharply. The city of Gaborone is estimated to generate about 3574 tonnes of waste electrical and electronic equipment in the year 2015, as compared to present generation of 658 tonnes. Management policy considering strategy of extended producer responsibility and establishment of institutional infrastructure for collection, storage, treatment, disposal and recycling should developed for the management of WEEE in the city of Gaborone.
