Supercritical CO2 turns flyash into valuable products, toughens common materials
UFTO has established contact with a small company in Reno NV, Materials Technology Ltd., which has patented a process that uses supercritical CO2 to harden and seal concrete, and turns wastes like fly ash and sludge into materials which are strong, fireproof and waterproof.
Los Alamos National Lab has been actively testing the process for use in radioactive waste storage, and is issuing a press release today, January 20, citing its remarkable simplicity and tremendous implications and wide ranging applications. Stories may appear in the Wall Street Journal and elsewhere in the national press. Also see Scientific American, November 96, page 40, for a good overview of the technology.
Basically, SC CO2 has zero surface tension, and soaks completely through materials, effecting chemical and structural changes instantly that otherwise can take centuries (e.g., in the case of concrete–which hardens gradually over time).
The company met recently with top officials at DOE and received an enthusiastic response. UFTO has developed close contacts with the principals, who are looking for utilities to work with them. (One concept is to co-locate production of these materials at power plants, and use their ash and CO2.)
I have additional information. You can also contact them directly, or browse their Web site at www.mtltech.com.
