Abstract
One embodiment is a safe including an outer wall formed of a metal, an inner wall formed of the metal, and a coarse aggregate and fill material filling a gap between the outer and inner walls. The fill material, such as a metal or thermoplastic with a melting point lower than the metal of the inner and outer walls.

A method, comprising:
- constructing a wall of a safe from sheet steel;
- exposing an intermediate space of the safe;
- heating the intermediate space until a fill material within the intermediate space reaches a liquid phase, the fill material having a melting point lower than a melting temperature of the sheet steel;
- draining the fill material from the intermediate space;
- and
- separating materials of the safe for recycling.
