  COMPOUND REMOVES RADIOACTIVE MATERIAL FROM POWER PLANT WASTE. LAYERED SULFIDES BOND TO STRONTIUM 90, OTHER RADIOACTIVE IONS.
Strontium 90 is a common radioactive by-product of fission in nuclear power plants. When extracted from the reactor along with other isotopes, a mixture is created made up of the radioactive material and inert ions like sodium and calcium.

  ‘BACTERIA POWER’ USED TO REDUCE WASTE
Australian scientists are creating a range of bacteria-based products, which can clean up toxic dumps and convert waste into usable material, to tap into a $5 billion a year global environmental biotechnologies industry.

  WHITE HOUSE ANNOUNCES INTENT TO BUILD WORLD’S FIRST ZERO-EMISSIONS POWER PLANT. COLUMBIA UNIVERSITY SCIENTIST CHALLENGES ACADEMIA AND INDUSTRY T
A long-time advocate and designer of zero-emissions power plants, Dr. Klaus Lackner was thrilled with President Bush’s statement that the United States will sponsor a $1 billion, 10-year demonstration project to create the world’s first coal-based, zero-emissions electricity and hydrogen power plant, but Lackner calls for an even larger vision.

  BIODEGRADABLE REINFORCED PLASTICS COULD REPLACE LANDFILLS WITH COMPOST HEAPS, CORNELL FIBER SCIENTIST BELIEVES.
Instead of landfills clogged with computer and car parts, packaging and a myriad of other plastic parts, a Cornell University fiber scientist has a better idea. In coming years, he says, many of these discarded items will be composted.

  DISCOVERY COULD BRING WIDESPREAD USES FOR ’NANOCRYSTALS’
Researchers at Purdue University have made a surprising discovery that could open up numerous applications for metal "nanocrystals," or tiny crystals that are often harder, stronger and more wear resistant than the same materials in bulk form.

  COMPOSTING PLASTIC
An Australian development means there will be one less thing to feel guilty about when you indulge in biscuits or chocolate - you will be able to put the packaging in the compost.

  INTERNATIONAL AWARD FOR CONCRETE FROM WASTE
An Australian scientist has won the concrete world’s most prestigious award for his work in turning industrial waste into a useful component of concrete for building and construction.

  NEW SYSTEM DEVELOPED FOR REMOVING CONTAMINANTS FROM STORM RUN-OFF
During heavy rains, storm water runs across streets and highways, picking up oil, gasoline, soot and other contaminants and eventually depositing it in rivers, streams and bays. While a variety of methods have been used to remove the contaminants before they reach local waters, their effectiveness varies. Thomas Boving, assistant professor of geosciences at the University of Rhode Island, may have just solved the problem by using a cheap and readily available material: shredded aspen wood.

  ENGINEERING PROFESSOR DISCOVERS A CATALYTIC PROCESS THAT COULD SAVE MILLIONS FOR PAPER MILLS
A catalytic process that could help paper mills save millions of dollars a year by converting a polluting by-product into formaldehyde, a useful product, has been discovered and patented by an engineering professor at Lehigh University in Bethlehem, Pa.

  MICROORGANISMS TURN MARSH WATER INTO DRINKING WATER
Minute bacteria, living in a zinc ore deposit and solidifying it, might assist in effective purification of ground waters on marsh lands. Bacteria can purify dirty water and significantly increase its quality - up to the standards effective on drinking water. Having treated water from contamination, bacteria pack these contaminants in zinc sulfide crystals.
