Chapter 4. Waste and financing: what innovations?
Chapter 4. Waste and financing: what innovations?
Solid waste recovery is often presented as facing mainly technical challenges. The previous chapters have shown that these are closely interlinked with territorial, social and governance issues. To this we should add the economic dimension, which imperatively needs to be controlled in any waste management system that aims for sustainability. The detailed case studies in this report describe many economic and financial innovations that help to finance a waste recovery service. This fourth chapter thus begins with an overview of the costs incurred by the different stages of waste management in the six case studies presented, then relates these costs to the effective service quality and the quantities treated by each of the final recovery or disposal methods identified in the previous chapters. Next, the goal is to understand how the service is financed and identify innovations in this area. We round off the chapter by highlighting the key enablers that can leverage the financial dimension of waste recovery in global South countries. These levers involve controlling and balancing budgets, seeking to make recovery profitable, and redefining the perimeter of the public service so as to compensate for the impossibility of financing the whole sector through public funding.

Waste management costs and the quality of service provision 1. Overview of the costs and quantities of managed waste
The costs of production and provision of waste management services The data collected from the municipalities did not allow the production costs of public waste management services to be calculated with any precision. The figures reported below are most often the costs of contractors’ service provision. This means that comparing them involves a real degree of uncertainty, but it does allow an analysis of the main trends. For Lomé, future costs relating to the commissioning of the new sanitary landfill were estimated. City
