Introduction
The rate of demolishing buildings in Namibia is very low, what mostly happen is renovation/extensions of old buildings plans. However when buildings get to finally be demolished, reuse of components as an alternative is explored.

What happens to recovered demolished materials?
• Common construction and demolished materials that are re-used include doors, corrugated irons, planks/ timbers, poles e.t.c this is an advantage because reusing makes a lot of economic and environmental sense.
• Mainly communities self-organise themselves to recover as much from demolished buildings as possible. Example, broken timbers are re-used as firewood and corrugated irons are re-used to make shack buildings as housing for the poor.
• Materials that are badly damaged after demolishing e.g glass are being recycled.
• Those that cannot be recycled are taken to landfill sites.
