Abstract
The study examined the impact of sustainable waste management practices on supplier selection criteria; a case of Riley Packaging Uganda Limited (RPUL), Mukono. It specifically focused on; examining the relationship between sustainable waste management practices and supplier selection criteria, examining the relationship between waste reduction and supplier selection criteria, examining the relationship between material recycling and supplier selection criteria, and
examining the relationship between safe disposal and supplier selection criteria in Riley Packaging Uganda Ltd. A cross-sectional survey research design was utilized for the study, and both quantitative and qualitative research methods were applied. Both basic random and selective sampling techniques were employed during the data gathering process, which involved questionnaires and interviews. The survey also employed a sample size of 80 respondents who work for RPUL and are part of the company's top management. The study findings revealed that waste reduction, material recycling, and safe disposal are widely practiced at Riley Packaging Uganda Ltd and all have significant positive relationships with supplier selection criteria, as evidenced by Pearson’s correlation results: waste reduction (r = .728**, p < .05), material recycling (r = .791**, p < .05), and safe disposal (r = .783**, p < .05), indicating that strengthening these sustainable waste management practices enhances operational efficiency, supply chain effectiveness, environmental responsibility, and the likelihood of selecting resource-efficient and compliant suppliers. Ultimately, the survey encouraged that Riley Packaging Uganda Ltd. reinforce waste reduction, recycling, and secure disposal practices, integrate sustainability requirements into supplier reviews, and promote environmental recognition amongst employees and providers to decorate sustainable procurement, enhance supply chain efficiency, and ensure environmentally accountable dealer choice.
