Salvaging means:
* To rescue or recover something from a dangerous or wrecked situation. For example, salvaging goods from a sinking ship or a fire.
* To reclaim something that has been discarded or lost. For example, salvaging old furniture or building materials.
* To make something useful out of something that was damaged or discarded. For example, salvaging a broken chair by using its parts to create a new one.
Essentially, salvaging refers to the act of saving something from loss or destruction and making it useful again.
