Paper Bags Are Better Than Plastic, Right? Answered
Paper Bags Are Better Than Plastic, Right?
Summary: The answer to the "paper or plastic?" dilemma is: Neither. They're roughly equal in pros and cons. While convenient addictions, they both gobble up natural resources and cause significant pollution. Get basic design benefits of a paper bag and plastic bag with our award-winning replacements - the ACME Bags Workhorse (the plastic bag replacement) and the EarthTote (the paper bag replacement). Same brilliant basic design as their wasteful relatives, but designed to be used thousands of times.
Issue 1: Energy and natural resources
It takes more than four times as much energy to manufacture a paper bag as it does to manufacture a plastic bag.

Of course, most paper comes from tree pulp, so the impact of paper bag production on forests is enormous. In 1999, 14 million trees were cut to produce the 10 billion paper grocery bags used by Americans that year alone. Paper bag production delivers a global warming double-whammy forests (major absorbers of greenhouse gases) have to be cut down, and then the subsequent manufacturing of bags produces greenhouse gases.
Issue 2: Pollution
The majority of kraft paper is made by heating wood chips under pressure at high temperatures in a chemical solution. As evidenced by the unmistakable stench commonly associated with paper mills, the use of these toxic chemicals contributes to both air pollution, such as acid rain, and water pollution. Millions of gallons of these chemicals pour into our waterways each year; the toxicity of the chemicals is long-term and settles into the sediments, working its way through the food chain. Further toxicity is generated as both plastic and paper bags degrade.
POLLUTANTS PAPER V.S. PLASTIC
Paper sacks generate 70% more air and 50 times more water pollutants than plastic bags.

Issue 3: Recycling
It takes 91% less energy to recycle a pound of plastic than it takes to recycle a pound of paper. But recycling rates of either type of disposable bag are extremely low, with only 10 to 15% of paper bags and 1 to 3% of plastic bags being recycled, according to the Wall Street Journal.

Although paper bags have a higher recycling rate than plastic, each new paper grocery bag you use is made from mostly virgin pulp for better strength and elasticity.
Issue 4: Degradability
Current research demonstrates that paper in today's landfills does not degrade or break down at a substantially faster rate than plastic does. In fact, nothing completely degrades in modern landfills because of the lack of water, light, oxygen and other important elements that are necessary for the degradation process to be completed. A paper bags takes up more space than a plastic bag in a landfill, but because paper is recycled at a higher rate, saving space in landfills is less of an issue.
