". . . I would also suggest that GRRN and others consider a boycott of
PET containers in general and support the purchase of juice and soda in
glass or aluminum (which we all know has recycled content)."
I want to respond . . . . .
Choosing one container material over another is tricky. It is true that
aluminum beverage cans have a relatively high recycled content level, thanks
to the relatively high (but still an "F" in my book) aluminum can recycling
rate of 56% in 1998. I would also like to add that without the VERY high
recovery rates for aluminum cans in container deposit states, the aluminum
can recycling rate (and thus the amount of recycled content in aluminum
cans) would be far below 56%.
We recycled 56 billion out of the approximately 100 billion cans sold. That
means 45 billion aluminum cans were trashed last year.
I have taken a crack at the 'energy' numbers and would welcome readers to
TAKE A CLOSE LOOK AT MY FIGURES AND GET BACK TO ME IF YOU SEE A MISTAKE.
In order to get a handle on the energy savings realized if 24 billion PET
soda bottles were replaced with 24 billion aluminum cans I made the
following assumptions:
Assumption #1: The PET bottles would be replaced by aluminum cans on a PER
UNIT basis not a volume basis. In fact, it is more likely that more units
of aluminum cans would be made to deliver the larger volume of soda
delivered by PET bottles.
Assumption #2:
194 mill btu's needed to make a ton of aluminum cans from virgin materials
45 mill btu's needed to make a ton of aluminum cans from recycled cans
47 mill btu's needed to make a ton of PET bottles from virgin materials
At 47 mill btu's per ton of new PET bottles, it takes about 40,285,714 mill
btu's of energy to produce 24 billion PET bottles -- the number of PET soda
bottles produced in 1998.
At the 1998 recycling rate of 56%, 13.2 billion new cans would be produced
from recycled cans, using 9,000,000 mill btu's of energy. Another 10.8
billion new cans from would be made from virgin materials, using 31,745,454
mill btu's of energy. Together that's about 40,000,000 mill btu's of energy
to make the 24 billion cans (45% from raw materials and 56% from recycled cans).
If my calculations are accurate, there would be no energy savings if the 24
billion PET soda bottles were replaced UNIT FOR UNIT with 24 billion
aluminum cans.
Now I realize this is just taking the energy use into consideration, but it
should certainly be part of the discussion.
Anyone care to comment??????
