Operator models for delivering municipal solid waste management services in developing countries. Part A: The...

Area of Science:

• Environmental Science
• Urban Planning
• Public Policy

Background:

• Municipal solid waste management (MSWM) in emerging and developing countries faces challenges in service delivery and sustainability.
• Operator models, defining the interaction between client, revenue collector, and operator functions, are crucial for effective MSWM.
• Existing research often seeks standardized solutions, overlooking local context variability.

Purpose of the Study:

• To present the evidence base for diverse operator models in MSWM for emerging and developing countries.
• To analyze the effectiveness of different operator types (public, private, micro-service providers) across various MSWM elements.
• To identify key factors for successful MSWM service delivery, beyond the operator model itself.

Main Methods:

• Analysis of evidence from 134 cases of municipal solid waste management.
• Detailed examination of 28 case studies focusing on operator models and their application.
• Categorization of operators into public sector, formal private sector, and micro-service providers.

Main Results:

• No universal 'standard' operator model is effective; cities utilize an average of 2.5 models per city.
• Micro-service providers are effective in expanding collection coverage in underserved areas and in recycling.
• Effective MSWM relies more on a strong client organization with political/financial backing than on the operator type alone.
• Municipalities generally pay operators through taxes or direct charges, not direct user fees.

Conclusions:

• Sustainable municipal solid waste management requires context-specific operator models, often a combination of public, private, and micro-enterprises.
• The capacity and stability of the client organization (municipality) are critical determinants of service success.
• Revenue collection mechanisms, typically municipal payments, are integral to the viability of operator models.
