From the 90s till this age, compostable bags are one of the most used stuff to carry vegetables or any items. To prevent damage to nature and the ocean side, it works exceptionally due to its great recyclable ability. But do compostable bags break down in landfills?

Sadly, most landfills don’t have the temperature that requires breaking down the compostable bags. Based on some factors (heat, bacteria, oxygen, and moisture), the compostable bags can break down quickly.

To explain the whole thing about this topic, stick with this guide till the end as I’ll describe it all right away. Keep On Reading …

Compostable Bags Disposed In Landfills

Do Compostable Bags Break Down In Landfills?

The compostable bags are created from bi-biodegradable plastic (agricultural source) by an Italian chemist and chief executive.

Just like plastic and other artificial bags, they will not break down in the landfills unless 4 things are present. These are:

  1. Temperature (Heat).
  2. Moisture.
  3. Bacteria.
  4. Oxygen.

With these four elements, they can break down if you recycle in the right way. So, can you put compostable bags in the landfill? Yup, you can!

But it’s better to know the temperature (heat) requirement to know if the bags will break down or not.  

  • If the compostable bags carry garden waste, then the temperature needs to be 60° C (140° F). It will take 30 – 90 days to complete the process.
  • If the compostable bags carry food waste, then the temperature should be 70° C (158° F). The duration will be around 1 to 3 months.

That’s What Happens To Compostable Bags In Landfill!

After placing the compostable bags in the landfill, there’s a lot of things occur. Let me explain this matter in steps for your understanding.

  • When the temperature is fine, the compostable bags will start to attract enzymes and bacteria. These will work continuously to compost the bag as an initial step.
  • Then, the oxygen will keep up with the microorganisms which helps the decomposing process. Thanks to the heat support, the weeds, microbes, and other plant diseases will pass away.
  • Although most landfills don’t contain enough moisture, there are some which contain moisture to break down the compostable bags.
  • Composite bags need to be placed in the landfill in any high-heat Industrials.
  • The proper disposal or breakdown will take up to a few months.

Frequently Asked Questions

How long do compostable bags take to decompose?

It might take up to 3 to 6 months (90 to 180 days) to decompose the compostable bags fully. However, it can change based on the temperature and moisture factors. 

What are compostable bags made of?

Most compostable bags are built out of natural plant starch such as wood pulp and corn starch which doesn’t cause damage or toxic effect. Some of them can be made using other vegetables like potatoes which help the composting system.  

Are compostable bags better for landfills?

Compostable bags are a great waste management solution for the landfill. You only need to ensure a proper compost of them to get a better trash experience.

Wrap Up

It requires good knowledge to answer whether compostable bags break down in landfills or not, which you have now. 

Most folks don’t know the exact way of disposal to work the compostable bags as a fertilizer in the landfills and later complain about them. 

They are great for the land to ensure better rotten ability while not damaging anything. I hope you find this guide handy to get information related to this topic.
