The Trouble with Plastic Bags

Although plastic bag and thin film plastic recycling is now quite widely available in many grocery stores, most plastic bags are not recycled.  

The City of San Francisco estimates that after offering in-store plastic bag recycling for 10 years only 1% of bags were recycled. Nationwide it is estimated that only 3% of plastic bags are recycled.

Plastic bags do not breakdown in landfills. Most estimates state a breakdown period of 1,000 years or longer.  It is up to all of us to keep plastic bags out of landfills.

All too often thin plastic bags are put in curbside recycling bins and in blue public recycling bins meant for hard plastics, glass and aluminum and cans.  When plastic bags get into the system at a recycling facility that accepts curbside recycling, they snag conveyor belts and wheels in the sorting machines, bringing the whole process to a grinding halt.

Mike Tunney of Waste Management told the Chicago Tribune in March 2016 that he stops his recycling plant five times a day to remove the numerous bags clogging the machinery.  There are so many bags contaminating the line, workers can’t possibly snag them all.

Plastic bags clog up storm drains.  In San Jose, California, a plastic bag ban led to an 89 percent reduction in the number of plastic bags winding up in the city’s storm drains.  Using reusable bags helps keep trash off the streets.

Plastic bags are even found washing up on the shores of Antarctica.  Hundreds of millions of plastic bags are circulating in lakes and oceans. 80% of the plastic bags floating in the ocean originated from open dumps and not from ships.

According to The Wall Street Journal, the U.S. goes through 100 billion plastic shopping bags annually. An estimated 12 million barrels of oil is required to make that many plastic bags.

Four out of five grocery bags in the U.S. are now plastic.

What About Paper Bags?

Transporting paper bags to stores requires more energy than transporting lighter in weight plastic bags.


Bring Your Own Sturdy Reusable Bags

Reusable bags are the better choice over plastic or paper bags; but what kind of reusable bag?

Some stores have started handing out thicker, reusable plastic bags to replace the old single-use bags. Jordan Parker, founder of the environmental advocacy group Bring Your Bag Chicago, notes that the thicker reusable plastic bags require five times more energy to produce compared to thin plastic bags. They can harm the environment more than the single-use bags because it's unknown how many consumers are reusing the "reusable" bags and how many are simply throwing them away after only a few uses.   And although these bags can be recycled when they tear, energy is required to recycle them. 

Sturdy cloth and cotton string bags can be reused thousands of times and will last for years.  They can be washed to be kept clean for multiple uses.

What Do I Do With My Old Bags That I Already Have?

Green Minds LFLB believe that it is best to reuse them as many times as possible. Clean plastic bags can be reused to store other stuff in, they can be used to pick up after dogs rather than buying more plastic bags, they can be used for trash can liners.

The plastic bags, plastic film etc you cannot reuse can be brought to the stores for recycling.

Green Minds LFLB also suggests that you reuse your paper bags as many times as possible. When they can't be used any longer they are perfect liners for kitchen compost bins - it is a lot easier to get all the kitchen scraps out when you have a liner, and at the same time you use less water when rinsing the compost bin.

During the Covid-19 pandemic we feel it is important to address the increased use of plastic bags. Plastic bags are not safer than fabric bags, as long as each customer handles their own bags, and wash them between each store visit. You can even help keep the grocery store staff safe by keeping your bags in your cart while shopping and bagging. Single use bags comes from a long supply chain with excessive handling. The limited studies so far suggest that viruses like Corona and Sars survive longer on smooth surfaces such as plastic than on porous surfaces such as paper or fabric.

We interviewed a disaster medicine doctor and advisor to several Covid-19 state and government departments. He says the safest approach for the environment and your own health is to:

1. Wipe down the cart you pick before you start your shopping trip

2. Select your groceries in the store

3. Do self check out and pay with touchless method. Wipe down check out monitor before your start 

4. Put all your groceries back into the cart

5. Leave the store with your groceries in the cart loosely

6. Wipe everything down as you bag into your own bags in your car

7. Wash your own bags between each store visit.

Most importantly everyone should do what they feel keeps them and their family safe. 

In our area we would like to sent special thanks to Marianosfor having dedicated check out lines for customers bringing their own bags and bagging themselves. And to Costco for having staff wiping carts between each customer and encouraging customers to bag in their cars into their own bags. Thank you for keeping your patrons safe. Let us know if you know of other stores that should be recognized!
