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