The 10 Best Biodegradable and Compostable Trash Bags you Should Buy in 2020

In Kitchen by Iqbal HakimLeave a Comment

Currently, we have a plastic waste crisis on our hands. The number of non biodegrading plastic waste in the environment is rapidly increasing, while landfills are getting filled up with plastics that takes centuries to degrade.

Because of that, we should strive to lessen our use of plastic drastically. One of the most used plastic products are plastic bags, and in this case, trash bags.

One of the easiest methods to reduce plastic in the environment is to reduce our use of trash bags. Humans produce on average 1,1 kg of trash per day, while OECD countries average 2,2 kg of trash per day per person. That’s a lot of trash, with 7,8 billion people on earth, that means, there’s about 8,58 billion kg of trash produced every single day.

A lot of those trash are disposed using plastic bags to the nearest landfill. Aside from hiding the unsightly waste, plastic bags also reduce the foul odor so that it won’t disrupt public activity.

Sadly, that also means that there are a lot of plastic bags that are rotting away in our landfills. They can’t degrade by themselves because a lot of plastic is non-degrading, or at least takes a couple of centuries to fully degrade.

The solution? Use biodegradable trash bags. There are numerous benefits of using biodegradable and compostable trash bags compared to your regular plastic bag.

What Are Biodegradable and Compostable Trash Bags?

In essence, a biodegradable and/or compostable trash bag are trash bags that will decompose if left in nature for a set period of time. If it’s also compostable, it will degrade into organic materials and finally soil.

How to Choose The Right Biodegradable and Compostable Trash Bags

Just like picking a regular trash bag, when choosing the right compostable and biodegradable trash bag, you also have to consider things like size, price, and added features. These are the basic parameters that you have to evaluate to find the right trash bag.

However, when picking compostable and biodegradable ones, there are a few extra things that you have to look for.

Biodegradable vs Compostable

They may sound the same and you might feel that they’re no different, but there’s a difference in the certifications and standards for these two products.

Biodegradable bags are cheaper, but they don’t degrade as easily compared to compostable trash bags

Biodegradable bags are cheaper, but they don't degrade as well as compostable bags

Bags that are labeled as “biodegradable” are often made from innovative plastics and polymers that are able to decompose naturally, under the right circumstances. However, those circumstances usually require light and oxygen, two things they won’t have under a pile of trash in a landfill.

Luckily, some biodegradable trash bags have added chemicals that helps the plastic break down in any environment. This ensures that it’s able to degrade anywhere without external help.

It’s also a lot harder to recycle a bag made out of biodegradable plastic as it needs to be sorted in a certain way. The special plastics and polymers usually don’t play well with regular plastics.

That being said, biodegradable bags hold together really well (due to them being made out of plastic) and are often cheaper than compostable bags. This makes them a more wallet friendly option if you’re willing to sacrifice some eco-friendliness.

Some biodegradable bags may even be fully compostable and just don’t carry the certification due to manufacturing differences. Just note that if your city or municipality requires compostable bags, they cannot be merely biodegradable.

Compostable Bags Break Down Faster!

Compostable bags breaks down really fast, faster than biodegradable bags

If you’re looking for something that will break down really fast in the environment, look for bags that are labeled as “compostable”. Unlike biodegradable bags, these bags are regulated and will decompose under nearly any conditions.

Keep an eye out specifically for those that are BPI and ASTM D6400 certified. If you live in Europe, also look out for the Austrian TUV or the OK Composting certifications. Not only are these bags proven to break down fast, but your city composter will also be sure to accept them.

Don’t forget, though, that because these bags are compostable, they’re going to start breaking down pretty quickly if you have any wet and/or organic matter in them. So you’ll need to change your bag fairly often or try to keep food scraps in a separate container. One trick is to line them up with newspapers if you frequently dispose of wet waste to reduce moisture content.

Most biodegradable, compostable trash bags are made from plant starch, either potato or corn starch. While both will break down equally well, potato starch bags are just a bit more environmentally friendly. Potatoes require less water and take up 40% less land to produce the same amount of starch compared to other plants. Because of that, if you want to minimize your environmental footprint, potato is the way to go.

Thickness is Important!

If you fill your trash bags with heavy waste, pick thicker bags!

We all know that plant starch based trash bags are not as strong as their fully plastic based ones. But, you’ll be surprised at how well they handle regular use.

If you usually fill your trash bags to the brim, remember to pick a fairly thick trash bag to reduce the chance of ripping or tearing. You don’t want any of those food waste spilling all over your kitchen floor do you.

Anything over 1 mm of thickness is classified as a heavy duty bag. These bags will be able to withstand anything the average household throws at them at daily basis.

Remember, pick thick bags over thin ones if you prefer to fill them up to the brim.

Drawstring and Handles are Usually Not Included

Biodegradable trash bags and compostable ones usually don't have any handles
You’ll have to learn a few knots if using biodegradable or compostable trash bags

Most biodegradable and compostable trash bags don’t have ties and handles like many traditional trash bags. Handles and drawstrings are normally made with heftier, reinforced plastic, that’s stronger than the bag itself. So, it’s harder for manufacturers to produce these in line with the rest of the bag due to certification reasons.

Be aware that unless the box explicitly states that the bags do have drawstrings, you’ll likely have to tie the corners together yourself. But considering the fact that these bags generally need to be changed more frequently than normal plastic bags, that might not be much of an issue.

You won’t fill these up right to the brim, right?
