Issue #1 - Energy
required to manufacture plastic vs. paper
takes more than four times as much energy to manufacture a paper bag as it
does to manufacture a plastic bag.
primary reason for this is that it takes only one-eighth as much material
to produce a plastic bag.
Issue #2 - Pollution
majority of kraft paper is made by heating wood chips under pressure at
high temperatures in a chemical solution. The use of these toxic chemicals
contributes to both air pollution, such as acid rain and water pollution.
sacks generate 70% more air pollution than plastic bags.
sacks generate 50 times more water pollution than plastic bags.
Issue #3 - The Landfill
film is estimated to account for less than 3% by volume of municipal
landfills compared to 97% other materials.
weight, plastics account for only 7% of the U.S. landfills compared to 36%
Issue #4 -
takes seven trucks to deliver the same quantity of paper bags contained in
one truck of plastic bags.
Issue #5 - Recycling,
Reuse and Source Reduction
takes 91% less energy to recycle a pound of plastic than it takes to
recycle a pound of paper.
use of plastic bags reduces solid waste by reducing the need for new bags.
bags are 90% thinner than their paper alternatives and the use of these
thinner, superior films has had a significant impact on reducing the
volume and weight of plastics in municipal landfills.
Issue #6 - Degradability
additives can be blended with polyethylene resin to make them
"oxo-degradable," allowing them to degrade over a period of time
when exposed to various outdoor elements. Upon degrading, they will not
leave fragments, methane or harmful residues.
