Abstract
Electronic waste (E-waste) is one of the fastest-growing waste streams at present due to significant technological progress and enhanced use of information and telecommunication (IT) equipment. New Zealand is one of the developed countries where e-waste related regulation is not yet formalized, and voluntary schemes are currently in place, instead of mandatory and/or co-regulatory arrangement. The aim of this study is presenting a Weibull distribution-based sale-stock-lifespan model by which e-waste generation estimation is done for computer and IT equipment from the year 2001 to 2025.The results of the study showed that in the year 2001, sales of small IT, desktop computers, printers, telecommunication equipment, and mobile phones were just under 2000 tons, cumulatively, which increased to over 10,000 tons in the year 2015. With linear regression, it is estimated that sales of the selected components will reach around 15,000 tons in the year 2025. The annual growth rate of IT equipment sales is estimated to be close to 9% from the year 2000 to 2015. Using the model, it is quantified that e-waste generation was 145.94 tons in the year 2000 which increased and reached 5335 tons in the year 2015 which will increase to 10512.67 tons in the year 2025. From 2000 to 2015, annual growth rate of e-waste generation is estimated to be just over 25%. The results of this study provide valuable information to the policymakers developing formal e-waste management system by understanding quantity of e-waste generation in New Zealand.
