List the product or process systems analyzed in this inventory:.
Key Assumptions: List and describe.
For each system analyzed, define the boundaries by life cycle stage, geographic scope, primary processes, and ancillary input included in the system boundaries.
Postconsumer Solid Waste Management Options: Mark and describe the options analyzed for each system.
□ Closed-Loop Recycling
Basis for Comparison:
□ This is not a comparative study. □ This is a comparative study.
State basis for comparison between systems: (Example: 1000 units, 1000 uses)
