The future looks bright for infinitely recyclable plastic

Plastics are a part of nearly every product we use on a daily basis. The average person in the U.S. generates about 100 kg of plastic waste per year, most of which goes straight to a landfill. A team led by Corinne Scown, Brett Helms, Jay Keasling, and Kristin Persson at Lawrence Berkeley National Laboratory (Berkeley Lab) set out to change that.
Less than two years ago, Helms announced the invention of a new plastic that could tackle the waste crisis head on. Called poly(diketoenamine), or PDK, the material has all the convenient properties of traditional plastics while avoiding the environmental pitfalls, because unlike traditional plastics, PDKs can be recycled indefinitely with no loss in quality. ....

From Smoky Skies to a Green Horizon: Scientists Convert Fire-Risk Wood into Biofuel

Reliance on petroleum fuels and raging wildfires: Two separate, large-scale challenges that could be addressed by one scientific breakthrough.
Teams from Lawrence Berkeley National Laboratory (Berkeley Lab) and Sandia National Laboratories have collaborated to develop a streamlined and efficient process for converting woody plant matter like forest overgrowth and agricultural waste – material that is currently burned either intentionally or unintentionally – into liquid biofuel. Their research was published recently in the journal ACS Sustainable Chemistry & Engineering.
“According to a recent report, by 2050 there will be 38 million metric tons of dry woody biomass available each year, making it an exceptionally abundant carbon source for biofuel production,” said Carolina Barcelos, a senior process engineer at Berkeley Lab’s Advanced Biofuels and Bioproducts Process Development Unit (ABPDU). ....
