Question 1 of 30
Dr. Anya Sharma, an environmental consultant, is conducting an LCA for a novel bio-based polymer intended to replace conventional plastics in food packaging. During the impact assessment phase, she discovers that the production of a specific enzyme used in the polymer\'s synthesis contributes significantly to eutrophication in nearby water bodies, an impact not initially considered substantial during the scoping phase. Furthermore, the initial data on the enzyme\'s production was based on industry averages, lacking site-specific details. According to ISO 14040:2006, what is the most appropriate next step for Dr. Sharma to ensure the robustness and reliability of her LCA results, considering the iterative nature of the methodology?
Proceed directly to the interpretation phase, acknowledging the eutrophication impact as a limitation in the final report, and suggest further research for future LCA studies.
Refine the scope of the LCA to exclude the enzyme production step, focusing instead on the polymerization process and the end-of-life scenarios of the bio-based polymer.
Revisit the life cycle inventory (LCI) phase to gather more specific, site-related data on the enzyme production process, potentially expanding the system boundary to include upstream processes involved in the enzyme's raw material sourcing and manufacturing.
Apply a weighting factor to the eutrophication impact category to minimize its influence on the overall LCA results, thereby maintaining the original scope and focus of the study.
