Ajisegiri Musa S, Owotomo Taiwo A

The study assessed the economic and environmental benefits of waste battery recycling in Lagos State, Nigeria. Multistage sampling technique was employed to administer 65 copies of structured questionnaire to companies and individuals involved in waste battery recycling site area. Data obtained were analyzed using principal components analysis (PCA). The results obtained using component loadings of ± ≥ 0.8 as the criteria for selection of the variables reduction in importation (0.801) PC₁ was accountable for 20.35% of total variance, promotion of economic development opportunities (0.841) PC2 was responsible for 19.02% of the total variance, job creation opportunities (0.871) PC₃ was accountable for 16.96% and reduction in industrial costs of sourcing material/energy production (0.911) PC4 was accountable for 15.35% of total variance as perceived economic benefits of waste battery recycling and they jointly accounted for 71.7% variation in the perceived economic benefits data set. The results obtained using component loadings of ± ≥ 0.7 as the criteria for selection of the variables also identified reduction of greenhouse emission (0.787) PC₁ was accountable for 24.67% of the total variance, soil erosion control (0.845) PC₂ was responsible for 19.89% of the total variance and energy/cost saving (0.789) PC₃ was accountable for 17.41% of total variance as perceived environmental benefits of waste battery recycling with 62% of the total variance in the environmental benefits data set. The study recommended the need for government to encourage waste battery collection by creating ready markets for scavengers of waste batteries.
