Biodegradable Plastic Manufactured From Air And Bacteria
There’s no oil involved, which means we can keep our plastic
addiction going on without causing quite so much damage.  Not
all plastics are created equal. Some are the bane of the
environment. Oil is pumped out of the ground, "cracked" under
high heat and pressure, and the resulting chemicals are formed
into drink bottles, computer keyboards, and other goods.
Disposing of them often releases toxins, cripples sea life, and
wreaks other kinds of environmental havoc.  Other plastics are
now being designed that are manufactured by microbes and
disappear back into the environment once we’re done with them.
One class of such biodegradable plastics known as PHA, (that
stands for polyhydroxyalkanoates), has come into its own.
Although around for decades, new ways to build PHA
molecules—essentially long strings of carbon, hydrogen, and
oxygen atoms—by harnessing microorganisms have made PHA
competitive with commercial, oil-based plastics.  Newlight
