Are syringes biodegradable?

This blog post will answer the question, “Are syringes biodegradable” and cover topics like the biodegradability of syringes and frequently asked questions related to the topic.

Are syringes biodegradable?

No, syringes are not biodegradable. They are constructed of plastic that takes centuries to break down into microplastic.

Can Syringes Be Recycled?

The first thing to know is that recyclable plastic materials are used to make syringes. Polypropylene (PP) & polyethylene (PE) plastics are the kind of plastics they use. This indicates that it is OK to recycle them depending on the materials they were created from. 

Then then, this is not all you need to know. Let’s go on a little bit.

Because they are constantly in touch with bodily fluids and blood, syringes are often vulnerable to contamination much like their needles. 

Because of this situation, syringe needles are never recycled even if they are composed of metal.

Even if the interaction with liquid and blood in syringes is minor, we cannot completely exclude this possibility. Because of this, many recycling businesses are selective about accepting syringes for recycling. 

Syringes are often put through various procedures by those who take them in order to remove any impurities that could be on them. Without a doubt, the recycling business needs a lot of capacity to handle this. And not all of them possess this capability.

This explains why it could be difficult for you to find a recycling firm willing to take syringes from you. In addition, collecting large quantities of syringes may be quite stressful. 

Syringes are tiny, as you’ve seen, therefore it’s not a good idea to recycle them one at a time. You may be able to recycle syringes if you can get enough of them. Syringe recycling may be simply impossible in any other case.

Used syringes: Can they biodegrade or not?

Used syringes are not biodegradable, just like unused ones. This is a result of the components that make up the syringe. A syringe’s body and plunger are constructed of polypropylene. This synthetic resin cannot be broken down by bacteria.

Rubber, another non-biodegradable material, is used as the plunger seal on syringes. Why can these materials not decompose naturally? They are synthetic because they are made from artificial materials.

It takes a very long time for these manufactured substances to decompose. Additionally, they harm the surroundings by doing so.

The expected decomposition time for polypropylene alone is 20 to 30 years. Rubber is reported to take anywhere from 50 to 80 years to degrade.

What is the greenest option given that syringes do not biodegrade? The greatest chance is for more study and production to go into the international trade of eco-friendly syringes.

These syringes are non-harmful to the environment and may only be used once. They disintegrate without harming the environment. Could there be such a thing as an eco-friendly syringe? Yes! They really already do.

Disposable syringes composed of polyester resin, which breaks down without affecting the environment, are now under research. We anticipate that advancements in manufacturing technology will make these syringes a practical choice for usage on a global scale.

Are syringes dangerous?

There are certain things with which we do not often interact. Therefore, we must be aware of how to handle them and securely dispose of them when we do.

By doing this, we may appropriately maintain our health. What about needles, then? Do they pose a risk? Syringes are very dangerous. Here are a few of the explanations.

  • Syringes come into touch with body fluids including blood and urine.
  • Syringes could be exposed to infectious fluids
  • You run the risk of getting an infection if you get a piercing or come in touch with used syringes on your skin.

Having said that, there are a few things to keep in mind while getting rid of syringes.

Here are a few pointers that will enable you to handle them safely at work.

  • Put on leather gloves.
  • Verify that you know where the closest sharps container is.
  • Avoid removing the needle’s cap from the needle or attempting to reconnect the needle to the syringe. Place the syringe and needle in the sharps container.
  • Get in touch with your neighborhood’s hazardous waste authority when the sharps container is full. They will be able to arrange for you to properly dispose of the sharps container.

Is it prohibited to discard syringes?

Yes, it is unlawful to discard syringes. Since they often think they have a monopoly on what they use and how to dispose of them, many others may find this amusing. Here is the law telling you no. So, be composed and avoid getting into problems.

This is for a variety of reasons, which we’ll go through in the sentences that follow.

Syringe disposal is seen as health, safety, & environmental concern. Many individuals often fail to remove the needles from the syringes & dispose of them in this manner. 

The constant contamination of used needles and syringes, might harm landfill officials and expose them to illnesses.

This legislation has been in effect in the state of California since 2008, and many individuals have complied with it throughout the years. Contrary to the custom, used coffee tins cannot be filled with syringes or needles and discarded. 

According to California legislation, some weekends will be set aside for individuals to deposit their used and bundled needles in landfills. There is also a pick-up service available for senior people who may have mobility issues.

In general, remember that it is now against the law to dispose of used syringes in many regions of the nation when you do so next. Instead, you must bag them appropriately and dispose of them in accordance with the law. We’ll go more into this in the section that follows.

Can You Reuse Syringes?

There is a new trend that emphasizes utilizing the resources at our disposal carefully. Some people have developed the practice of using them repeatedly till they feel worn out for items that are not made of separate components. 

While this works well for the certain office or household supplies, we should never do it with medical supplies like needles.

Syringe reuse may be very harmful to people’s health. The cause is that syringes, like their needles, often come into touch with bodily fluids like blood. and should be thrown away after each usage. 

You put yourself at risk for simple infection transmission if, after using the syringes & needle to deliver dosages, you discard the needles & reuse the syringes.

Overall, the rule is to never reuse syringes or needles. You must carefully dispose of them after using them to give the dosages.

How Can Used Syringes Be Disposed of Safely?

You’re probably unsure of what to do at this point. First, due to potential health risks, it is not advised that you recycle your old syringes. Furthermore, you cannot recycle or discard syringes, in contrast to other items. 

The law forbids it. It seems that you have knots in your hands. There are, however, appropriate methods to get rid of your syringes. You can rely on us to never abandon you.

How to get rid of your syringes may be found below. Let’s leave.

Remember that your syringes might be considered either sharp trash or biohazardous garbage, as we said before. That is not over with this. As a result of this categorization, you should dispose of them appropriately. Let’s think about them now.

  • The Sharp Waste of Syringes
  • Syringes as Biohazardous Waste

I will now elaborate on these.

The Sharp Waste of Syringes

Here’s what you need to do if you’re throwing away your syringes as sharp waste.

Get a sharp rubbish bucket, please. These containers are often marked with biohazard symbols or special labels. You’ll place your used syringes in them as soon as you obtain this.

You must provide certain information if you are discarding your syringes as sharp waste from a hospital or other institution. The name of your institution, a phone number, and a location are a few of those specifics. 

You may call for a pick-up of the sharp waste or wait until the specified weekend to do it, depending on the legislation in your state.

Syringes as Biohazardous Waste

Here is what you need to do to dispose of your syringes as biohazardous trash.

You must purchase a bag for biohazardous garbage. These bags often come in red and are either marked as biohazardous or include a symbol. 

You’ll place your syringes in this bag as soon as you obtain them. This needs knowing the specifics of the disposer, much as when disposing of syringes as a sharp waste.

When you’ve finished, place the bagged syringes in a biohazard trash container, the type that is often lined with red plastic bags and has a lid.


In this post, we discussed the biodegradability of syringes, how to dispose of syringes, and the toxicity of syringes.

Frequently Asked Questions(FAQs), “Are syringes biodegradable?”

Syringes: can they be biodegraded or not?

Polypropylene is often the material used to make syringes. Despite being secure & recyclable, only around 1% of polypropylene gets recycled, and the majority of it is destined for landfills. 

Additionally, since it is non-biodegradable, there are significant environmental concerns.

Syringes – hazardous waste or not?

Syringes, needles, broken glass, and other objects that may penetrate the skin are included in the category of sharps trash, which is a subset of infectious waste. 

They are among the most harmful wastes generated in the healthcare industry due to their pathogen contamination and capacity to penetrate the skin’s barrier.

What happens to spent needles and syringes?

Your medical waste supplier will transfer your sharps containers to a treatment facility once they get them. Here, discarded needles & syringes are sterilized so they may be disposed of safely. Sharps are handled using the autoclave process.

How are discarded syringes disposed of?

Plastic syringes should be thrown away right away once the needle is removed in a container that matches its color and has a plastic liner bag. Syringes should not be combined with other possibly infectious trash while being cleaned and recycled.

How are syringes made?

Production Process

For improved PP clarity, molding is done in a refrigerated environment. The rubber is then put together with the molded syringes. 

The whole assembly is then sterilized using ethylene oxide in a sterilization facility. The finished syringe is then automatically packaged in blisters.

What happens if a syringe is used again?

Once used, a syringe and needle must both be thrown away. Reusing the syringe while changing the needle is unsafe since it increases the risk of disease transmission. 

Patients who reuse needles or syringes run the risk of contracting HIV, hepatitis B virus, and hepatitis C virus.
