Effect of a modified lifetime model on e-waste generation in Nigeria under defined reuse options

Reliable data on e-waste generation is important for environmentally sound management systems. This study models from existing electrical electronics imports, consumption and Nigerian households. Structured questionnaires were used to obtain information Electrical Electronic Equipment (EEE) use, reuse, disposal households in Nigeria Data placed the market (POM) obtained United Nations University (UNU) five EEE types (TV, DVD player, refrigerator, desktop laptop) between 1995 2019 using apparent method. A forecast up 2020 backcasts 1980 made based these data. The lifetime profile EEEs was modeled Weibull distribution function characterized by a time-varying shape parameter scale parameter. POM of selected analyzed fit into functions. differences reuse non-reuse options show that around 54 million units players; 106 CRT TV; 22 refrigerator; 11 laptops 24 computers would have been delayed transiting stream 1981 through options.   Key words: waste, electronic equipment, distribution, re-use repair, recycling, Nigeria.
