The United Nations estimated the volume of rubble and rubble that must be removed at 37 million tons in the Gaza Strip.

“We estimated that there were 37 million tons of rubble, or about 300 kilograms of rubble per square metre, in the Gaza Strip, which before the war was densely populated and urban,” UNMAS official Per Lodhamar said.

He pointed out, during a regular press statement to the United Nations in Geneva, that “removing it will take 14 years, assuming the use of about 100 trucks.”

He stressed that the unexploded ordnance was mixed with the rubble, which would greatly complicate the mission.

Lodhamar considered that "at least 10% of the munitions fired in the conflict do not explode, and thus they pose a constant threat to the population, to the teams responsible for searching the rubble to recover the bodies of the victims, and to the workers tasked with removing the rubble."

He explained that "65% of the destroyed buildings were residential" in the Gaza Strip.
