Japanese construction company Taisei Corporation has developed a form of building demolition that’s far more quiet, healthy and environmentally-friendly than traditional methods. And it doesn’t even involve wrecking balls or explosives.

The process is called “Ecological Reproduction System"

Using a crane, material from the interior of the building is removed. That includes beams, concrete, paneling, etc. In this way the process is kind of like a reverse assembly line, taking apart the structure bit by bit. 

Basically, the building disappears floor-by-floor. And as the material is taken out, the company makes sure that anything reusable is recycled and re-purposed
