2. Coverage in this workshop Summary (Session 4)Summary (Session 4) For understanding AIM/Material model –What is AIM/Material model? –Model formulation –Necessary data for simulation –Future scenario Training (Session 5)Training (Session 5) –Operation of AIM/Material model Application (This session)Application (This session) –Application of AIM/Material model to India and Japan

3. Application of AIM/Material model ModelModel –Basic economic structure is the same as the training model –The differences are as follows; Disaggregate the environmental industryDisaggregate the environmental industry More detailed solid waste typeMore detailed solid waste type Three types of waste treatment: direct final disposal, direct reuse, and intermediate treatment.Three types of waste treatment: direct final disposal, direct reuse, and intermediate treatment.
