​One of the most comprehensively defined bioderived polymers, in terms of their chemical, physical, biological and degradation properties, is polylactic acid (PLA).
​
PLA is compostable and made from corn or sugar which is fermented to produce lactic acid and, through a series of chemical transformations, is converted to its polymer.
​​
It is the most extensively used fossil-fuel plastic replacement, in part thanks to its versatile properties enabling its wide-ranging applications.
