How does corn-based plastic stand up against its petroleum based counterpart?
Polylactic acid (PLA), a plastic substitute made from fermented plant
starch (usually corn) is quickly becoming a popular alternative to
traditional petroleum-based plastics. As more and more countries and
states follow the lead of China, Ireland, South Africa, Uganda and
San Francisco in banning plastic grocery bags responsible for so much
so-called "white pollution" around the world, PLA is poised to play a
big role as a viable, biodegradable replacement.
