Researchers win Nobel Prize with `green chemistry'

France's Yves Chauvin and Americans Robert Grubbs and Richard Schrock won the Nobel Prize in chemistry yesterday for their work to reduce hazardous waste in forming new chemicals.

The trio won the award for their development of the metathesis method in organic synthesis -- which focuses on how chemical bonds are broken and made between carbon atoms.

"This represents a great step forward for `green chemistry,'" the Nobel Prize committee said.

Chauvin, 74, is the honorary director of research at the Institut Francais du Petrole in Rueil-Malmaison, near Paris.

Grubbs is a professor of chemistry at the California Institute of Technology, and Schrock is a chemistry professor at the Massachusetts Institute of Technology.
