Witt and Shah of Biopolymer Network Limited, New Zealand foamed polylactic acid materials by impregnating PLA resin beads with CO2.  The method is carried out by contacting the beads with liquid CO2 and holding the impregnated beads at a temperature and pressure that prevents the beads from foaming while allowing the level of impregnated CO2 to reach 4 to 20 wt%.  The polylactic acid resin should have an amorphous content of at least 50 wt%.  (RDC 10/17/2012)
