Operational Factors Affecting Public-Private Partnership (PPP) in Sustainable Solid Waste Management in Lagos Metropolis
This study examines the extent to which household characteristics, attitudes, lack of remuneration and behavioural factors have affected the effectiveness and sustainability in solid waste management by the public private partnership (PPP) operators. Using Multi-stage sampling technique, structured questionnaires were administered on 274 households in low, medium and high population density areas. Descriptive and inferential statistics were used to analyse the data. The study revealed that the most challenging factors are the household use of polythene bags or sacks (38.38%) instead of the conventional wastes containers and none or poor remittance of the fees (49.20%) by service users, which affects the frequency of waste collection. The Chi-square results confirm that there is significant difference between the frequency of waste collection and effectiveness in waste management (waste storage and payment of service fees) [X2 (12) = 293.38, p < 0.05] by the PPP operators. The conclusion is that the use of polythene bags or sacks and non-remittance of service fees are the critical factors affecting the efficient and effective operation of PPP in solid waste management. Therefore, conventional waste storage containers and adequate remittance of fees by the households are recommended to improve the operations of PPP for a sustainable solid waste management.
