The focus then turns to municipal solid waste (MSW) where data on quantities and composition as well as past trends and future projections are presented (Section 3.3). Section 3.4 overviews the status of MSW management across income groups and regions. It focuses first on the protection of public health by ensuring that all wastes are collected, and then on environmental protection by phasing out uncontrolled disposal and open burning of waste. This is followed by an examination of the global industry in secondary materials (Section 3.6).
