Sugar cane (as bioethanol source)
Used for production of bioethanol since 1930’s Commercial production of bio-PE started Sept 2010 Currently 200kton bio-PE facility of Braskem LDPE production is close to 20mln tonnes

From sugar(cane) to PE
Sugar is fermented to ethanol C6H12O6 → 2 CH3CH2OH + 2 CO2
Ethanol is dehydrated to ethene 2 CH3CH2OH → 2 CH2=CH2 + 2H2O
Ethene is polymerized into PE
Mass efficiency 31%

Corn (biomass source of PLA)
Corn can be used for starch and starch plastics Main producer of PLA (Natureworks) uses corn as biomass Current production of Natureworks ~140 kton Commercial production of lactic acid via fermentation
since 1881 Corbion (Purac) is the largest producer of lactic acid

Production of lactic acid and PLA
Corn starch is hydrolysed into sugars Sugar is fermented to lactic acid C6H12O6 → 2 C3H6O3
Lactic acid is dimerized into lactides 2 C3H6O3 → C6H8O4 + 2 H2O
Lactides are polymerized into PLA
Mass efficiency 80%
