This study discussed the estimation of asbestos waste generation from both dispersed and undispersed asbestos building materials in building demolition by comparing three possible future outcomes, from “30±2 years Longevity Scenario”, “Simple Remaining-rate Function Scenario” and “Floating Remaining-rate Function Scenario”. The main results are as follows,
1. Each scenario led quite different future outcomes, especially in case of undispersed asbestos building materials wastes. And there is a possibility of leading the false outcome by “30±2 years Longevity Scenario” for the generated period and the maximum quantity.
2. “Simple Remaining-rate Function Scenario” and “Floating Remaining-rate Function Scenario” led similar outcomes in case of dispersed asbestos building materials wastes, though the latter is a little less until middle of the 2020's.
3. These outcomes have a big influence on the future management of processing and disposal of asbestos waste.
