Sustainable Reverse Logistics Practices and End-of-Life Ecological Performance of Mobile Phones in a Growing Economy

This study investigates the relationship between sustainable reverse logistics (SRL) practices, specifically repair, refurbishment, and recycling and end-of-life ecological performance (EoL-EP) in a growing economy. A descriptive survey research design was adopted. It focused on two prominent mobile phone service hubs in Port Harcourt, Nigeria: Garrison and the MTN Zone. A purposive sampling approach was employed to capture insights from 138 participants, including repairers, recyclers, and scavengers engaged in EoL phone handling. Data were collected using structured questionnaires developed from established literature, translated into Pidgin English to enhance clarity and reliability. Reliability and validity were confirmed through Cronbach's Alpha, exploratory factor analysis (EFA), and expert review. Data were analyzed using descriptive statistics and multiple regression with the help of SPSS version 25. Additionally, Structural Equation Modeling (SEM-PLS) was employed to assess the relationships between sustainable reverse logistics practices (repair, refurbishment, recycling) and end-of-life ecological performance (EoL-EP). Results demonstrate a significant positive relationship between SRL practices and EoL-EP. Repair practices minimized premature waste generation, refurbishment extended product lifespans and consumer utility, and recycling provided direct ecological benefits through resource recovery, waste diversion, and reduced emissions. Collectively, these practices improved ecological efficiency while generating operational benefits such as cost savings, enhanced sustainability positioning, and customer loyalty. Firms should integrate structured SRL practices into their reverse logistics strategies, while policymakers are encouraged to reinforce extended producer responsibility regulations and invest in recovery infrastructure to maximize ecological benefits.
