Embodied energy for selected classes of plastic resin. The top
part of each bar is for manufacturing energy (including recovered energy),
and the bottom part is for material energy.

Embodied energy in plastic material can be compared to that for other
produce than most materials of construction in the table except for
aluminum. Like aluminum, plastics also have to be removed from a finite
in-ground resource pool and have to be refined before use; both can be
recycled as well.
