Japan is planning to launch an experimental project in the new fiscal year from April that will help predict the amount of waste generated in a large-scale disaster and figure out the most efficient way to dispose of it.

It will be the first experiment utilizing a 3D city model — a project recreating a city in digital space. The program is aimed at developing a system to speed up waste disposal, which is considered key to quick recovery and rebuilding disaster-hit areas.

Following the Great East Japan Earthquake in March 2011, around 20 million tons of disaster waste, such as debris and damaged furniture, were generated in affected areas, in addition to tsunami sediment, hindering recovery and relief efforts.
