Sanitary landfill requires much greater initial investment and hence higher operating costs than controlled dumps. Sanitary landfill technologies were introduced in Lagos and Onitsha two decades ago. But presently the landfills are not operational. Open dumping is the most common practice. There is no landfill regulation or standard that provides a basis for compliance and monitoring. Wastes in open dumps are set on fires in order to reduce the volume of the wastes.
