How much building debris is salvaged after a natural disaster?

Most people hire demolition/cleanup crews whos main interest is quick money. Restoration and salvage is not "quick" money in comparison to demolition. They actually get more money to clear out quickly, so off to the dump the trucks go after the heavy equiptment levels and loads the property so the reconstruction can begin. After a disaster business need to get up and running ASAP because they are losing money each day they are not open. Homeowners just want their life back ASAP. Therefore salvage take a low priority. It is ashamed but true.

My friend is down in Peru helping with the aftermath of the earthquake. She says that beautiful old tiles and other reusable material are just being thrown away. Is there any way to send a scout - or a professional dumpster diver of sorts - to comb these landfills for reusable material? I thought that homeowners would hold on to things of value and reuse it in their rebuilding efforts, but new materials are so cheap that I am afraid there is no economic incentive in place for salvaging. If you hear of any programs or companies that provide this type of economic incentive, please let me know. Thanks.

Even if you rescue building materials, such as your Peruvian tiles, they must be hand sorted, cleaned, boxed, shipped, etc. This is very labor-intensive, and a lot of man-hours usually means a lot of cost (perhaps not in Peru). This frequently makes the cost of rescued building materials far higher than new materials. There are a few rare exceptions, such as certain bricks. The rising green movement in US construction may change all of this. LEED standards are driving many building materials to be recyclable (which is quite different from reusable).

@ALM…Their answers are sad…But your Question and bringing this to light,.. very cool
( on the kimmie cool meter ).
