Question 2: Where Does All the Construction Waste Go?
In October 2021, I visited a demolition construction site in Seoul. A two-floor brick house built in the 1980s was demolished to make way for a five-floor reinforced concreted neighbourhood living facility. An excavator with a claw-shaped crushing bucket known as ‘crusher’ attached to its arm pressed down the roof, toppled the wall, and pulled down the barebone structure in a gentle gesture. A water sprinkler was used to manage the dust cloud and a 2.5-ton truck was brought in to carry away the waste. It took less than a week to remove all traces of a building that had remained in place for almost half a century.
A representative from the waste processing company that I met at the site noted that about 3.5 – 5m of waste is collected per 3.3m area in demolition work.
