Drink containers with recycled content. The drink containers
of Figure 10.1 use recycled materials to different degrees. How does the
ranking in Table 10.2 of the text change if the contribution of recycling is
included? To figure this out, multiply the energy per liter in the last column
of the table by the factor

where frc is the recycle fraction in current
supply, Hm is the embodied energy for primary material production,
and Hrc is that for recycling of the material. The following table
lists values for the drink-container materials
