We hear the question almost every time we go grocery shopping. Some shoppers answer automatically: plastic – convinced that they are making a better choice for the environment. Others ask for paper, believing the very same thing. The reality is that both paper and plastic bags gobble up natural resources and cause significant pollution. When you weigh all the costs to the environment, you might just choose to reuse.

Consumption:

  • Americans consume more than 10 billion paper bags each year. Some 14 million trees are cut down annually for paper bag production.
  • Four out of five grocery bags in this country are plastic. The U.S. uses 100 billion plastic bags annually, made from an estimated 12 million barrels of oil.
  • Worldwide, an estimated 4 billion plastic bags and end up as litter each year. Tied end to end, the bags could circle the Earth 63 times.

Production:

  • Paper, of course, comes from trees. Trees are grown or found, then marked and felled.
  1. Logos are moved from the forest to a mill, where there is a three – year wait for the logos to dry before they can be used.
  2. Logos are stripped of bark and chipped into one – inch squares. The chips are “cooked” with tremendous heat and pressure.
  3. Then, they are “digested” with limestone and sulfurous acid until the wood becomes pulp.
  4. The pulp is washed, requiring thousands of gallons of fresh water and bleach, then pressured into finished paper.
  5. Cutting, printing, packaging and shipping to make paper bags require additional time, labor and energy.
  • It takes more than four times as much as much energy to manufacture a paper bag as it does a plastic bag.
  • Energy to produce bags:
  • Plastic is 594 BTUs.
  • Paper is 2,511 BTUs
  • 7 in 10 Americans do not know that plastic is made from petroleum products, primarily oil, according to a recent nationwide online survey.
  • Plastic is a by – product of oil refining. Plastic bags are made from polyethylene, which comes from oil refineries as small resin pellets.
  1. A machine heats the pellet to about 340 degrees and pulls out from it a long, thin tube of cooling plastic.
  2. A hot bar is dropped on the tube at intervals, melting a line.
  3. Each melted line becomes the bottom of one bag and the top of another.
  4. The sections are cut out and a hole for the bag’s handles is stamped in each piece

Pollution: 

  • The use of toxic chemicals during the production of paper for bags contributes to air pollution, such as acid rain, and water pollution.
  • The production of paper bags generates 70 percent more air and 50 times more water pollutants than production of plastic bags.
  • Plastics production requires toxic chemicals. In an EPA ranking of chemicals that generate the most hazardous waste, five of the top six were commonly used by the plastics industry.
  • Hundreds of thousands of marine mammals die every year after eating discarded plastic bags. Turtles think the bags are jellyfish, their primary food source. Bags coke animals or block their intestines. 

Recycling:

  • Paper must be returned to pulp by using many chemicals to bleach and dispense the fibers. 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. Bags that are recycled and often turned into corrugated cardboard, not new paper bags.
  • It takes 98% less energy to recycle a pound of plastic than it takes to recycle a pound of paper.
  • Plastic is 17 BTUs.
  • Paper 1,444 BTUs.
  • But recycling rates of both types of bags are extremely low.
  • Percentage of bags recycled:
  • Plastic is 1 – 3%
  • Paper is 10 – 15%
  • Recycling almost any kind of plastic involves remelting and re – forming it. Because bags must first be separated by the type of plastic they were made from, the process is time – consuming and expensive. For example, it can cost $4,000 to process and recycle 1 ton of plastic bags. This can then be sold on the commodities market for about $32. More often than not, bags collected for recycling never get recycled. A growing trend is to ship them to countries such as India and China, where they are cheaply incinerated under more lax environmental laws.

Biodegradable:

  • Paper is degradable, but it cannot completely break down in modern landfills because of the lack of water, light, oxygen and other necessary elements. About 95 percent of garbage is buried beneath layers of soil that make it difficult for air and sunlight to reach it.
  • Even though petroleum – based plastic will never biodegrade, nearly 4 in 10 believe plastic will biodegrade underground, in landfills or in the ocean.
  • Petroleum – based plastics are not biodegradable, meaning they will not decompose over time. But they do take up less space than paper in a landfill: 2,000 plastic bags weigh 30 pounds; 2,000 paper bags weigh 280 pounds.

What can you do?

  • Invest in high – quality reusable bags, each of which has the potential to eliminate an average of 1,000 plastic bags over its lifetime. The bag will pay for itself it your grocery store offers a 5- or 10- cent credit per bag.
  • Any collapsible plastic crates and keep them in your car. At checkout, food goes into the crates, making it easy to bring food into the house in one or two trips.
  • No bag at all? Think twice about requesting a plastic bag if your purchase is small and easy to carry.
  • Reuse the bags you have. Line your litter box with them; crumple them and use them for packing; cut the handles off, and add some string and make a toy parachute; use them for an impromptu diaper pail; line your trash cans with them; be creative.
  • Keep reusable bags in your home, office or car so they are available when you go shopping. 
I'm Miss. Congeniality of Broward College North Campus, Events Coordinator of the Psychology Club at Broward College North Campus, new president of Her Campus Broward, I work for Student Services at Broward College North Campus, and I just like to get involved in many great activities that benefit my personal growth.
Student at Broward College for the past five years, first enrolled on Davie's Central Campus learning Physical Therapy for two years than, transferring to Coconut Creeks North campus for the last three years, now majoring in Early Childhood / Developmental Education. Spent first year with Her campus Broward as Outreach Director, former president of self-entitled campus friendship club, Sammy's Buddy Brigade, member of the Campus Science Club, and a Broward County local student Ambassador with Best Buddies International. Winner of the Sammy's award for most charity work within the community, and now Vice President of Her Campus Broward. I hope to soon be working at Junior Achievement with the elementary and middle school children, in order to have a well rounded experience! The hope is to one day work with and teach children who have special needs such as myself! Biggest belief and philosophy of life is that, no matter what anyone says you can't accomplish in life, I am living proof that anything is possible! Having ADHD, high functioning Autism, and medical conditions such as Scoliosis, helps me to understand special needs children on a level that very few people can! It is this very knowledge that led me to choose Teaching as my chosen profession. Now at age 42, and more than 55% on the way to getting an Associate of Arts degree in Early Childhood Education, I hope to become an Assistant Teacher within the next year or so. We hope that this true life story will inspire others to never give up either, no matter what anybody says, or tells you, that you can't do, the only one who can truly hold you back is "YOU".
