A methodology is developed for the modelling and analysis of waste management (WM) aspects in growth oriented national planning in a systems' framework. Four models developed at different levels of aggregation, i.e., W-G model, I-O-W model, GP model, and B-C model, have been reviewed with reference to their basic framework, special features, and applicabilities. The basic technologies used in these models are simulation, input-output analysis, goal programming, and physical system theory. The aspects involved in the long-range planning of input /, output O, and wasteWparameters have been outlined with particular reference to the use of these models. Aggregation-disaggregation procedures, resource-wise as well as sector-wise, have been presented to facilitate the integration of models at different levels of aggregation. A coordinated view of these models is presented in the form of a flow chart, which may be used for planning and monitoring the economic growth profiles. Some broad guidelines to national policy on WM have been enumerated.
