It can be reduced to ash but it takes a lot of heat. I can't think of anything in it that would burn except the air trapped in it. In basic form it is just portland cement, sand, gravel and water. Incineration seems like an energy inefficient way to dispose of a pretty inert, innocuous waste. Must be done because landfill space is valuable.
The landfill space is the issue. He said that even with what they are burning in the current plant, the landfill would only last until 2025.
From the site:
"It will reduce the amount of waste currently being landfilled by up to 85 percent, delaying for many years the need to develop a new landfill in Palm Beach County."
A PDF on the facility:
CLICK ME! I emailed the guy and he's a bit miffed at me. He feels he was misquoted.
I seem to have replaced his "incinerate" with my "burn". By "incinerate" he means "reduce to ashes". He says that concrete is "fully oxidized"; it does not burn. But, the water in the concrete is boiled off and without the water the concrete turns into powder.
Any rebar would inevitably be melted and sold off. Only the ash gets buried. The metals are recovered, and like the recyclables, they have people who buy that stuff. Panzer, perhaps.
He'll be really miffed if he knew it was about a porn board post ....
