Integration of the official and private informal practices in solid waste management

Solid waste management in low income developing countries is generally theresponsibility of the official sector, such as municipal corporations. However, thereare extensive inputs from the from the private informal sector in waste collection,separation and recycling. Four different activities in the private informal sectorhave been studied to identify the potential of their integration with the officialsystem. Where integration means that the official sector accepts those practicesand incorporates them into existing practices and future plans. All the cases have been selected from the city of Karachi, Pakistan. A multiple case study approachwas adopted to assess the potential for integration, constraints to integration,attitudes, relationships and dependencies. It has been concluded that under thepresent circumstances, the private informal activities in solid waste managementcannot be integrated formally with the official system. The main constraints tointegration are public and municipal attitudes, the interrelationships anddependencies, interference by politicians and the lack of understanding on thewide range benefits of integration. Future models must be developed on the privateinformal practices within the official systems, such as primary collection of wastethrough municipal sweepers. A number of benefits of the private informal practices were also highlighted by the research which may be considered as opportunities once integration takes place. The recommendations include a number of actions and potential policy changes which could be done to promoteintegration and a better partnership between the private informal and the publicsector.
