What is the Difference Between Compostable and Biodegradable?

In the never-ending search for green products and solutions, two words come up often: Compostable and Biodegradable. But what do they mean? Is one better than the other? What do you need to know?

As always, PJP is here to help. We’ve been in the business of selling disposable products for 55 years, and we have made a commitment to protecting the environment. We’ll teach you the ins, outs, pros, and cons of both Compostable and Biodegradable products.

What is Biodegradable? 

Simply put, something is “biodegradable” if it can be disintegrated by bacteria, fungi, or some other biological process. If you look at the word itself, the meaning is right there. “Bio” meaning “life,” “degrade” meaning to break down, and “able” of course meaning that it can happen. Biodegradation is basically just the process of nature taking its course and breaking down materials to their component parts. Plastic will break down into carbon dioxide, water, and a few other things. Pretty simple, right?

The truth is that lots of things are biodegradable, if given enough time. Plastics in particular are known to take decades or even centuries to break down naturally, but they will break down. So, technically speaking, they are biodegradable. Even diapers, notorious for lasting a long time in land fills, will break down eventually.

When a packaging company says that their product is biodegradable, all they really mean is that it will break down when placed in a land fill. This is a good thing! obviously we don’t want products that last forever sitting in our land fills. The key, however, is to take note of how long it takes for the product to biodegrade. Some products degrade in months, while others take years. When shopping for green products, the less time for biodegradation the better.

What is Compostable? 

We’ve all heard of a compost heap, right? When you take organic materials and allow it to decompose which then creates fertilizer for your soil. Composting is the process of recycling organic waste so that it can eventually be reused.

In the packaging world, compostable means something a bit different. Typically, what a packaging company means when they call their product “compostable” is that it can be turned into compost… if entered into an industrial composting facility. This is an important distinction. Compostable products do not always biodegrade naturally in a landfill. They have to be placed in the right kind of conditions, conditions that are often only found in industrial compost facilities. Compostable products will take much longer to break down if in a landfill, especially an “air locked” landfill where there will be no oxygen.

Compostable products are great for the environment, but it is important to make sure that your business has the proper waste management processes in place. Make sure that your compostable waste is going to a compost facility.

What’s the Difference? 

The primary difference between compostable and biodegradable is that compostable products require a specific setting in order to break down, whereas biodegradable products break down naturally. Typically composting is a faster process, but only under the right conditions. Both of these kinds of products are better for the environment than plastic products that can take hundreds of years to disintegrate.

    What’s up, this weekend is pleasant in favor of me, because this moment i am reading this enormous educational article here at my residence.

  • cat hat

    The other day, while I was at work, my sister stole my apple ipad and tested to
    see if it can survive a forty foot drop, just so she can be a youtube
    sensation. My apple ipad is now broken and she has 83 views.

    I know this is totally off topic but I had to share it with someone!

  • cat hat

    Wow that was unusual. I just wrote an extremely long comment but after I
    clicked submit my comment didn’t show up. Grrrr…

    This is misleading information and very dangerous.
    Biodegradable items, while breaking down faster will create microplastics.
    Compostable plastic may also create microplastic issues if not treated correctly in a specially certified commercial hot composting facility.

    Stop using plastic, this should be your takeaway.
    Please update the article.
