Compostable Trash Bags

Compostable Trash Bags: The Eco Friendly Choice

Let’s talk about heroes. Not the cape-wearing, shield-wielding variety, but everyday heroes that quietly make a difference. Like trash bags. More specifically, compostable trash bags. Before you raise an eyebrow, consider this: every year, we churn out billions of plastic bags worldwide. They clog our oceans, fill our landfills, and even hang around in trees, pretending to be leaves. But what if we could replace them with an alternative that’s as kind to the Earth as it is effective at holding trash? Enter, the compostable trash bag – the unsung hero of waste management.

The Growing Problem of Plastic Waste

Why Should You Care About Plastic Trash Bags?

Picture this. Your home is spotless, but your trash bag is bursting at the seams, groaning under the weight of food scraps, soda cans, and yesterday’s news. Out it goes, into the bin and out of sight. But while it might be out of your hair, it’s not gone. It’s off on a journey to join its plastic comrades in a place not so far away: the local landfill.

The Scale of the Problem

With enough plastic trash bags used annually to circle the Earth 300 times over, we’re not just talking a hill of plastic waste; we’re talking mountain ranges. And these aren’t your ordinary mountains that wear away over time due to wind and rain. No, these mountains are here to stay.

Introducing: Compostable Trash Bags

What Are Compostable Trash Bags?

Now, imagine if you could use a trash bag that does disappear when you’re done with it. No, not some kind of David Copperfield disappearing act, but genuinely breaks down into nothing harmful. That’s exactly what compostable trash bags do.

The Science Behind Compostable Bags

Compostable bags are truly a marvel of modern science. Their design is predicated on the principles of composting, a natural process that turns organic material into a nutrient-rich soil conditioner. Here’s how the magic happens.

Compostable bags are primarily made from plant-based materials like corn starch, PLA (polylactic acid) and PBAT (polybutyrate adipate terephthalate). This might sound like a chemistry class gone wild, but stay with us. Cornstarch is a natural polymer, which is transformed into a plastic-like material known as PLA. PBAT, on the other hand, is a synthetic polymer that provides the bag with flexibility and strength. So, you get the environmental benefits of a compostable bag with the performance of a traditional plastic bag.

Once you’re done using them, compostable bags can be placed into a compost pile or bin. Here, in the presence of moisture, oxygen and heat, microorganisms get to work breaking down the material. What’s left at the end of this process is water, carbon dioxide, and biomass. This biomass is a nutrient-rich substance that enhances soil health and fertility.

The rate at which this happens varies based on conditions like temperature, humidity, and the presence of the right microorganisms. But in a controlled composting environment, a compostable bag can decompose in as little as 10 weeks. That’s a blink of an eye compared to the hundreds of years a conventional plastic bag takes to degrade!

The above details are supported by numerous scientific studies and references. For example, according to the article “Biodegradable and compostable alternatives to conventional plastics” published in Philosophical Transactions of the Royal Society B, compostable plastics made from polylactic acid (PLA) and other plant-based materials can successfully biodegrade in industrial composting facilities.

It’s worth noting, however, that these bags should ideally be composted in industrial facilities designed to handle compostable plastics. Home composting may not provide the necessary conditions for these bags to fully decompose.

This science stuff might not be as thrilling as a superhero movie, but we think it’s pretty cool. After all, compostable bags might not be able to fly or shoot lasers from their eyes, but they’re fighting the good fight against plastic waste, one bag at a time!

Advantages of Using Compostable Trash Bags

Environmentally Friendly

We’re not claiming that switching to compostable bags will put you on the same level as Captain Planet, but hey, it’s a start! By reducing the amount of plastic waste, you’re taking a step towards a cleaner, greener Earth.

Convenient and Easy to Use

Whoever said doing your bit for the environment had to be hard? With compostable trash bags, it’s as easy as replacing the bags you currently use. No fuss, no muss.


Not just for kitchen scraps, compostable bags can be used for anything from yard waste to pet waste. They’re like the Swiss army knife of trash bags!

Countries Leading The Way With Compostable Trash Bags


In a bold move, Italy waved arrivederci to single-use plastic bags and introduced compostable alternatives nationwide. Today, Italian citizens are gleefully filling their compostable bags, knowing they’re contributing to a cleaner, greener future.


France took the eco-friendly baton and sprinted with it, banning all plastic plates, cups, and cutlery, in addition to plastic bags. Now, you can enjoy your baguette, fromage, and vin on compostable tableware. How’s that for chic sustainability?

San Francisco, United States

Meanwhile, across the pond, San Francisco is leading the charge in the United States. With a city-wide composting program and a ban on plastic bags, the City by the Bay is proving that where there’s a will, there’s a way.


Denmark has been an eco-warrior for years, imposing levies on plastic bags way back in 1994. Today, Danes use fewer plastic bags than any other country, a testament to their commitment to sustainability.


In Rwanda, you’ll get more than a disapproving look for using a plastic bag – you’ll get fined or even imprisoned! This East African nation takes environmental protection seriously, and it shows.

Innovative Advances in Compostable Trash Bags

Today’s compostable bags aren’t your grandmother’s brown paper bags. They’re innovative, high-tech, and designed to break down rapidly under the right conditions. Companies like Matter-Bi and BioBag are leading the way with bags that decompose in as little as 10 days!

Future Innovations

While the technology is impressive, we’re just scratching the surface. The future may hold compostable bags that break down even faster, or perhaps bags that can decompose in the ocean. The possibilities are endless, and we can’t wait to see what’s next.

Things to Consider When Switching to Compostable Trash Bags

Compostability vs Biodegradability

When shopping for eco-friendly trash bags, remember not all “green” bags are created equal. While all compostable bags are biodegradable, not all biodegradable bags are compostable. And as we’ve learned, compostable is the gold standard in the world of waste disposal.

Quality and Durability

Sure, you’re saving the planet, but you don’t want to deal with a bag that rips and spills trash all over your kitchen floor. That’s why you should always look for bags that are renowned for their strength and durability.

Size and Capacity

Remember, you’re buying trash bags, not jeans. One size does not fit all. Always consider your trash output and the size of your bin when choosing bags.
