Packaging is an integral component of a wide range of goods today, impacting producers and consumers across the value chain. Growing interest in bringing bio-based and bio-derived packaging to the market is driving research and development in substitute plastics, like polylactic acid (PLA), to drop-in replacements, like Coca-Cola's polyethylene terephthalate (PET) PlantBottle, and finally, to new packaging materials with improved performance, such as Avantium's polyethylene furanoate (PEF). To evaluate the current bio-based and bio-derived packaging landscape, we completed a case study of the published ecoprofile and life cycle assessment (LCA) data from NatureWorks' PLA facility. We then further analyzed published life cycle inventory and assessment data for PET, PEF, and Coca-Cola's releases about the PlantBottle to see where the true value of bio-based and bio-derived packaging comes from.
Major industry investment is focused on drop-in and performance materials, but replacement polymers and composites won't give in and continue to scale and commercialize.
If reduced CO2 emissions are the goal, the value of NatureWorks' PLA lies in the use of renewable energy credits and not in the age of the carbon embedded in the polymer.
Bio-based and bio-derived packaging options reduce emissions and tackle sustainability concerns, but the effects are indirect - improved performance is where the real value lies.
