Conclusions
• Regulatory LCA is not likely to be used for non‐fuel chemicals alone in the near future
• Significant GHG emission credits for corn‐ethanol can be obtained by using only roughly 6‐9% of initial starch for production of biopolymers based on previous LCA theory
• Pay close attention to values in calculating credits per kg—these have to stand up in litigation to ensure the credit
• Credits are proportional to the mass of polymer produced
• Many theoretical issues are uncertain and credits will only be determined in conjunction with EPA
• Indirect emissions are uncertain and are a …
