The management of e-waste requires an understanding of the quantity and rate of transition of EEE to electronic waste (e-waste). This study used data generated from household survey to develop a life time model which reflects the specific reuse (often with repair and refurbishment) traditions common in developing countries and discusses how these influence ewaste generation – using Nigeria as a case study. The repair and reuse tradition in Nigeria deviated from the "linear economies" which often use and dispose electronic devices without co nsidering reuse options. Result shows that 74 % of respondent indicated that faulty EEE could be repaired and reused more than twice before disposal. Lifetime of the studied devices are extended by an average of 11 years for TVs, 9 years for ...

Both fungi were cultured together on the same Petri plate using three different pairing methods. Inoculation of each fungus on separate Petri plates served as controls. For each pairing method, experiments were conducted in five replicates. Radial growth (cm) of both C. gloeosporioides and T. longibrachiatum in all Petri plates were measured daily for 7 days. In all the three pairing methods, T. longibrachiatum significantly inhibited the growth of C. gloeosporioides (P > 0.0001). Growth inhibition of C. gloeosporioides by T. longibrachiatum was better in 'inoculating antagonist before pathogen' than in the other two pairing methods (P = 0.05). C. gloeosporioides had significant addition of radial mycelia only between days 1 and 2, as well as days 2 and 3 after pairing (DAP) before contact was made with T. longibrachiatum. Addition of mycelia mass of C. gloeosporioides slowed down significantly by the day upon contact with T. longibrachiatum (P = 0.05, R 2 = 0.86). F value for day after pairing (DAP) was also highly significant (P > 0.0001). T. longibrachiatum could thus be said to possess probable antagonistic tendency against C. gloeosporioides.
