Population & Poop

Let's do some math.

  • There are approximately 90 million dogs in the United States.
  • The average dog produces 3/4 pounds of poop a day.
  • That's over 67 million pounds of poop a day!

To prevent contaminating our air and water, the Environmental Protection Agency recommends scooping the poop with a bag and discarding it in the trash.








There are several ways poop bags could be disposed, but the end of life cycle for most bags is a landfill.

What's in a Landfill?

Landfills are sophisticated waste management systems which are highly regulated. When trash arrives at a landfill, it's buried. On a daily basis, the surface is covered with at least 6" of compacted soil. This controls litter, minimizes odor and protects public health.

The result?

A poop bag's final stop is an anaerobic environment which means it lacks oxygen. It's a dark, dry place and the bags are buried forever.

The Dilemma

As a conscious consumer, you would like to reduce your dog's environmental paw print, but there are many choices. Plain plastic is not an option, so which bag is the best?







The questions are endless...

The answer is... it depends on the bag's "end of life cycle".
Let's look at the options...


Made from plain plastic and an oxo-degradable additive, these bags are designed to degrade in an open-air environment.

The bags require oxygen to degrade, and a little heat and moisture accelerates the process. We've already learned these elements are not present in a landfill environment. Layers of dirt and debris cover the bags so they can not breathe.


Made from vegetable starches such as corn, sugarcane and beetroot, these bags require commercial composting.

This seems like a nice alternative but commercial composting is an extensive process. high heat, aeration, nitrogen and water are used to break down the plastic. They literally need to be cooked to perfection.

This is not your typical backyard compost pile and most municipalities do not allow pet waste in their compost facilities.


Made from synthetic polymers, these bags dissolve when immersed in water.

Although the EPA lists flushing pet waste as an option, they do not recommend flushing bags. The bags do not break down very fast and can cause strain on your pipes and municipal water treatment facilities.

Landfill Biodegradable

GreenLine Biodegradable Poop Bags are made from plastic and a proprietary additive which renders the bags biodegradable anywhere, regardless of environment.

This new technology utilizes the power of microbes and bacteria which are plentiful in landfill environments. They break down the barriers in plastic that prevent natural biodegradation to occur.

Hungry microorganisms looking for food to eat consume
the bag and produce natural, organic matter,
returning it to the earth.


Independent lab authentication proves the bags biodegrade 74% in 1014 days using test method ASTM D5511.

Additional testing is in progress. Come back or sign up for our email list as we'll update our results on this page as we receive them.



The Breakdown

You’ve done the math and determined dogs poop a lot!

You’ve learned that not all poop bags are created equal


You’ve discovered a poop bag that biodegrades anywhere.

Which bag will you choose?






(Hint, hint...)

Don't take our word for it


Once I found these bags, I have not used any others. Greenline bags do not have an overwhelming perfume smell. What I like best is how easy they are to open, making walks much easier and manageable. The fact that they biodegrade easier makes me feel better that I am not needlessly adding to the climate problem.

I LOVE LOVE LOVE this product.  The only thing I love more than my dog is finding a way to lessen my impact on Momma Earth. I love that these bags are biodegradable. I love that I can even buy them in bulk without additional packaging. I also love to support a locally owned women’s business. This product allows you to care for you fur friend while also keeping at least 3 plastic bags out of the garbage each day.

'As a petsitter and dogwalker, I go through a lot of poop bags. A client introduced me to GreenLine. That's when I learned the bags I was using did not break down when I tossed them in the trash. Well poop! I sing their praises at every chance and proudly carry them at all times. I'm thrilled to support a fellow woman owned business. In addition to being excellent poop bags they are incredibly handy for other things. I even use them as water bowls on my walks...'

I love Greenline poop bags! Have been using them for a few years now and love how durable these bags always are. Customer service is super nice and introduced me to the package free option for these bags, which is awesome for the environment. I use these bags when I walk my pup, Otto, but they are also great and perfectly sized for scooping cat litter with the neater scooper. Greenline is the best. Support women owned businesses. :)
