Key Assumptions: List and describe.

Boundary Definitions:

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)

If products or processes are not normally used on a one-to-one basis, state how the equivalent function was established.
