Economic Analysis of Waste Management in Nigeria

The generation, utilization and disposal of wastes (which constitute environmental hazards) are highlighted in this paper as a network flow problem. In this configuration, we construct and solve as optimal network flow, the problem of minimizing the cost of disposing wastes from sources of generation to dumpsites. Numerical applications based on iterative procedures suggest an appreciable (optimal) reduction in the cost of disposing wastes generated at production sites to various dumpsites.
