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.
Procedures concerning the handling of demolished buildings and construction materials in Namibia
Waste management hierarchy in order of Priority

Recovery& Reuse

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.
