Researchers determine the extent to which plastic contributes to climate change. It's a lot.

Roland Geyer's much lauded finding is a sobering one: 91 percent of the world's plastic waste has never been recycled.

Aging plastic leaches harmful chemicals. Rebecca Braslau has made it her life's work to create a safer alternative. 

More than 8.3 billion metric tons (9.1 billion tons). That’s the amount of plastic humans have created since the large-scale production of synthetic materials began in the early 1950s. It’s enough to cover the entire country of Argentina, and most of the material now resides in landfills or in the natural environment.

A professor challenges the ease with which we turn to synthetic materials.

UC Irvine's recycling process shows promise for meeting urgent waste and energy needs.

New method could see trash inexpensively recycled into other commodities.

Young researchers have spent the summer at UC Davis\' Genome Center working on what they hope will one day be the answer to cleaning up the world\'s landfills.
