A new 'green' building on campus: Montana State University's planned $40 mil science building will be a test bed for emerging clean technologies

Article Abstract:

The Montana State University is embarking on an ambitious $40 mil construction which will build a science building that incorporates the latest in 'green' technology. Structurally, most of the building materials to be used will come from mine tailings and coal fly ash from power plants. The building's energy system will use the latest in photovoltaic technology while sewage water treatment will utilize constructed wetlands system acting as 'living machines' to process both human and chemical waste. The building's ventilation system will use natural air recirculation.

Biosurfactants remove metals from soil

Article Abstract:

Researchers at the University of Arizona have found biosurfactants useful in removing metals from soils. Results from studies conducted on cadmium-contaminated soil reveal that rhamnolipids, which are substances released by Pseudomonas aeruginosa microbes, form stronger complexes with heavy metals leading to their removal. The surfactants' effectiveness, however, is diminished when a soil's clay content level increases.

Phytic acid immobilizes radionuclides

Article Abstract:

Argonne National Laboratory chemists are evaluating a new process for safeguarding groundwater. The process uses phytic acid to incapacitate radionuclides in the soil. Phytic acid is an economical compound that functions as a cation exchanger, according to researcher Kenneth Nash. Phytic acid, upon decomposition, liberates phosphate which then combines with heavy metals to produce safe sugars and insoluble minerals.
