I am a construction manager working with UHH to build a green building. One aspect we are working on is making use of our waste, rather than sending it the landfill.
The drywall cut-off have been ground and are available for use as a soil amendment here in Hilo. If someone were interested in taking it all, I would consider hauling it to your site.
Gypsum board is made of calcium sulfate dihydrate (CaSO4ยท2H2O), a naturally occurring mineral that is mined from dried ancient sea beds. This particular drywall from new construction, and is made from virgin mined material, with no recycled content, so it is pure calcium sulfate and paper. Here on the Big Island, it can contribute calcium to the soil, much as some people use coral sand for.
Here is a link to a paper describing gypsum: http://www.natureswayresources.com/resou...ypsum.html
If you are interested, or want more information, please contact me at 640-8134 or email me at godfreymik@msn.com
