Does Garbage Decompose? The Myth and What You Can Do About It at

Have you ever thought about what happens to your trash after the garbage truck hauls it off to the landfill? Not exactly a fun topic to dwell on right?!

I think we’re all pretty aware that our society produces A LOT of waste. We fill our garbage cans to the brim every week to be picked up and hauled off to the landfill. Out of sight out of mind, and most of it will decompose anyway, so it’s really not that big of deal, right?!

The answer is, unfortunately, no.

What really happens to garbage in the landfill?

A few years ago I attended a community event on getting started with composting. The speaker told us about a research project that excavated landfills, like one might excavate an archeological site, and the results were surprising.

Instead of disgusting, decomposing, rotting material, the team from the University of Arizona found trash that was 30-40 years old and still recognizable. In fact they used newspapers to date how long the trash had been in the landfill, because they were still legible!

The thing about our landfills these days is that they are built and designed not to leak toxins and chemicals into the surrounding ground and water. Of course, we wouldn’t want our garbage polluting our water supply!

Landfills are designed to isolate garbage from the environment. They are lined with a heavy duty plastic liner that keeps everything in and from leaking and covered with a daily layer of soil to keep out air and rain, as well as light from sun. But this design has the effect of keeping out the elements that are necessary for decomposition.

Because what does something need to biodegrade and break down into the environment? Light, air, and water. But none of those things are present inside a landfill. It is lined and covered and to keep all of those elements out.

So what does the garbage do? Hmmm, well, it just sits there of course.

In a landfill everything will look extremely similar to the way it looks when you throw it away. No rotting, no decomposing, no biodegrading, at least not at any noticeable rate. According to a New York Time article about the University of Arizona project, “There is biodegradation, but its pace is measured in centuries, not decades.”

So the argument of “Oh, I’ll just throw away this one paper towel, it’s no big deal, it will just biodegrade in the landfill,” is not really true.  No, it won’t biodegrade in the landfill, at least not for hundreds, maybe even thousands of years.

Reducing Our Waste

The average American produces 4.3 pounds of waste per day. PER DAY! That number mind-blowing when you start to think about how many people are in your family, live on your street, in your neighborhood and city; not to mention the whole country!

In other words, we produce an enormous amount of trash! And almost 55% percent of it ends up in the landfills where it will remain unchanged for generations. But it doesn’t have to be that way.

Over 50% of the waste we throw away is made up of food scraps, yard trimmings and waste, and paper products, much of which is compostable, meaning it will easily break down when exposed to the right environmental factors. Setting up a backyard compost pile and tossing this waste into the compost, instead of the landfills, can greatly reduce the amount of garbage our families produce!

The good news is that it is very easy to set up a simple compost pile in your backyard and begin throwing your food scraps and other compostable materials into it. In fact, did you know that there are at least 21 things that you can toss into your compost instead of your trash?

You can compost things like cardboard rolls, coffee grounds and filters, hair and pet fur, and dryer and vacuum lint! And find the full list here, along with things you should never put into your compost.

So with spring right around the corner (hopefully) begin thinking about how you can easily set up a compost pile in your yard to reduce the waste your family sends to the landfills. The bonus is, of course, that if you also have a garden, you will have rich, organic soil that will help your plants to thrive!

Did you believe the myth that garbage decomposes in the landfill? Have you considered composting? What’s holding you back?
