How to Choose a Compostable Trash Bag – Buying Guide

With so many compostable trash bags on the market, it may be hard to choose the best one for your needs. We've compiled a buying guide of tips and things to consider when buying a compostable trash bag. Read on below for more!

Be Sure it's Compostable, not Biodegradable

Biodegradable and compostable might sound the same, but the difference lies in official certifications, which may matter to you or your community.

Biodegradable Bags Will Break Down but Won't Disappear

Biodegradable Bags Will Break Down but Won't Disappear
Biodegradable trash bags are made of plastic formulated with microorganisms or chemicals that will break them down into smaller pieces. 

Depending on what makes up your biodegradable trash bag, those smaller pieces can become truly tiny and will decompose under the right circumstances.  These types of trash bags are known to break down faster than compostable trash bags might, and can often be a more cost-effective option. 


Unfortunately, the decomposition process for biodegradable trash bags requires light and oxygen, two things they won’t have under a pile of trash in a landfill. It's highly likely that your biodegradable trash bag won't completely break down, and it's also a lot harder to recycle the special plastic that they're made from. 

Compostable Bags Break Down Quickly and are Best if Potato-Based

Compostable Bags Break Down Quickly and are Best if Potato-Based
Unlike biodegradable bags, compostable bags are guaranteed to fully decompose into soil. Keep an eye out specifically for those that are BPI-certified. This means they meet the standards of the Biodegradable Products Institute. Not only are these bags proven to break down, but your city composter will also be sure to accept them.

Don't forget that because these bags are compostable, they’re going to start breaking down pretty quickly if you have any wet, organic matter in them. You’ll need to change your bag fairly often or try to keep food scraps in a separate container.

Either way, if you don't mind trash bags that are a little more fragile, you'll be able to manage your waste knowing that it will leave no footprint behind. Compostable trash bags don't need any chemicals or organisms to begin the decomposing process, so when they break down, it's a fully natural and eco-friendly process. 

For Larger Loads, Choose a Thicker Trash Bag

For Larger Loads, Choose a Thicker Trash Bag

If you're going to be throwing away larger amounts of waste, it might be a good idea to check the thickness of your compostable or biodegradable trash bag before you buy it. 

Compostable bags are known to be a little easier to break than biodegradable bags, so if you're looking to carry a lot of trash, you may want to invest in biodegradable bags.

 

Trash bag thickness is often measured in mils, with one mil being about one-thousandth of an inch. Standard trash bags average between 0.7 to two mils thick. In the case of biodegradable or compostable trash bags, you'll want at least one mil of plastic. If you have that much, you should be able to carry larger loads of trash without worry that your trash bag will break. 

Remember That Drawstrings and Handles Aren't Normally Included

Remember That Drawstrings and Handles Aren't Normally Included
Compostable trash bags rarely have ties or handles in the way that many traditional trash bags do. Handles and drawstrings are normally made with heftier, more reinforced plastic than the bag itself, so it’s harder for manufacturers to produce these in the same eco-friendly style.

That said, it's good to be aware that unless the box explicitly states that the bags do have drawstrings, you’ll likely be left to tie the corners together on your own. So long as you don't wait until the bag is full to the bursting, however, this shouldn't be too much of a problem.

How to Keep Your Garbage Bag from Smelling Like Garbage

How to Keep Your Garbage Bag from Smelling Like Garbage
If you’re getting a compostable bag, you might have to give up some fancy features of regular trash bags like odor elimination. However, you can add it back in using the following tips and tricks.
Add an odor absorber like baking soda, cat litter, or even dryer sheets to your trash can before putting the bag in. 

You can also mask the smell of waste with citrus peels or a few drops of essential oil. Just be sure to rid these additives of any excess moisture when possible. Finally, cleaning your trash can regularly helps to reduce the smell of trash. With these three steps, you should be able to keep your home odor-free.
