Plastic is everywhere.

Take 15 seconds to look around you right now. How many plastic items do you see?

It’s in your homes, your food, your personal hygiene products, it’s even in the rain!

In addition to the plastic you see everyday, many other products you use are filled with hidden plastics that we can’t see!

So let’s talk about the hidden plastics you encounter and how to avoid them!

What Is Hidden Plastic

You know what plastic looks like, feels like, and probably even smells like. But hidden plastic exists in many everyday products that are too small for us to see it.

These hidden plastics leak into the environment and wreak havoc. Once in the environment, they end up in farming soil, the air, and even rain.

Due to their small size (< 5 millimeters) smaller animals eat them which either damages the animals, or works its way up the food chain to humans.

Should We Be Concerned About Hidden Plastics?

Scientists have just begun studying these micro and nanoplastics because of the concern around plastics infiltrating the human body. Plastics have already been found in the bloodstream and more attention is being given to what the effects of our long term exposure will be.

But knowledge is power! Knowing where these hidden plastics lurk can help you cut them out and replace them with plastic-free alternatives!

15 Sources Of Hidden Plastic You Should Know About

1. Menstrual Products

Swap single use tampons and pads for reusable menstrual cups, washable cotton pads, and period underwear

Menstrual products sit inside your body or on your most sensitive bits for hours a day, for years of your life. Wrapped in plastic and made from synthetic materials containing known toxins, ~90% of pads and tampons are made of plastic.


2. Glitter

Swap out plastic glitter for no glitter

Glitter is sadly just tiny pieces of plastic. As such, keep it away from any sensitive areas and don’t wash it down the drain; it cannot be filtered out by water treatment facilities.


  • The best fix is to cut glitter out (both sad and difficult)
  • Bioglitter is the only alternative that has been independently verified to degrade in normal, natural conditions.

3. Receipts

Swap paper receipts for digital ones

If you avoid paper receipts, it turns out that might be the best thing for you. Receipts have a paper base that is coated in a fun little chemical you’ve probably heard of: BPA, a known toxin and endocrine disruptor that easily passes through skin into the body.


  • Leave it or opt for a digital copy if possible
  • Wash your hands after touching one — especially if you are pregnant.
  • Keep receipts out of reach from babies and toddlers.

4. Bandages

Swap out plastic bandages for bamboo ones

Obviously bandages have plastic waste, but the bandage itself is made from plastic and sometimes latex. When degrading, they leak toxic chemicals which you probably don’t want on an open wound.


  • Patch bandages are made from 100% bamboo and perfect for sensitive skin.

5. Tea Bags

Swap plastic wrapped tea bags for compostable bags or loose leaf

If your tea isn’t wrapped in plastic or contains individually plastic-wrapped tea bags, you’re off to a good start! But hidden plastics can be used to help heat seal the bag, keep the contents in, or keep the shape of the bag. This makes the bags non-compostable or degradable.


  • Steep & Mellow is completely plastic-free
  • Consider purchasing loose leaf tea in bulk & using a reusable infuser or a teapot.

6. Table Salt

Some sea salt brands contain microplastics

Up to 90% of Sea Salt brands actually contain microplastics! In the saddest scenario, microplastics exist in salt because of the levels of microplastic pollution in the sea where the salt comes from.


  • Himalayan Sea Salt
  • Rock Salt
  • Both contain none or the lowest amount of microplastics.

7. Kitchen Sponges

Swap plastic sponges for plastic-free cleaning tools

Your sponge cleans, it’s squishy, it does what it needs to do. Buuut sponges are made with plastic and a whole host of other toxic ingredients. After throwing them away when they get gross, they won’t break down in a landfill for centuries.


8. Disposable Wipes

Swap makeup wipes for reusable organic cotton facial rounds

There’s a reason baby wipes, wet wipes, makeup wipes, and all other disposable wipes aren’t flushable. They contain plastic and will not dissolve in water. Not only are makeup wipes terrible for your skin, most wipes are made from a cotton-plastic blend (AKA polyester).


9. Coffee Cups

Swap single use coffee cups for reusable travel mugs

To-go coffee cups may look like they’re recyclable paper but most are lined with plastic (it’s often not visible) to keep the liquid in. Paper recycling facilities can’t separate these materials out so they end up being trashed.


10. Chewing Gum

Swap plastic chewing gum for natural alternatives

We’re not talking about the great comedy by Michaela Coel, more like the stuff humans have been chewing for thousands of years. Today chewing gum is made from the same plastics used to make water bottles, plastic bags, glue, and tires: polyethylene, polyisobutylene, & polyvinyl.


11. Synthetic Fabrics

Swap synthetic fabrics for natural ones or use a microplastic catcher when washing

Plastics are hiding in our clothes in the form of synthetic fibers including but not limited to polyester, microfiber, & nylon. Everytime you wash them, they shed some microplastics that pass through filtration systems ending up in oceans, rivers, water systems, and polluting the environment.


12. Produce Stickers (& All Stickers)

Shop locally from farmers markets when possible

While produce stickers are technically low enough in toxicity to be edible, they’re made from plastics and adhesives (and not compostable either). Instead of decomposing they break down into smaller and smaller pieces.


  • Avoid the stickers when possible
  • Shop farmer’s markets
  • Refuse free stickers when offered

13. Aluminum Cans

Swap aluminum cans for glass jars

You may know that aluminum is infinitely recyclable, but you may not know that almost all aluminum cans are lined with a plastic or lacquer liner. You’ve seen Coke used to clean rust so it makes sense that the contents need to be separated from the tin. When recycled, the plastic is incinerated away and the aluminum melted to be reused.


  • Other than opting for glass packaging when possible, this one’s pretty unavoidable.

14. Takeaway Containers

Swap plastic takeout containers for tupperware

Even if it's brown and looks like cardboard, chances are it has a plastic liner to keep food from soaking through, Chinese food containers included. If it says “commercially compostable” look for a bin within the store to drop it in, it cannot be composted at home.


15. Beauty Products

Swap toxic beauty and skincare products for cleaner alternatives

From glitter in makeup, to abrasives in toothpaste, to exfoliants in scrubs, and even in shampoos, microplastics are hidden all over the cosmetic industry for a plethora of purposes. While there are restrictions around their use, when the top 10 cosmetic brands were studied, 87% of the products contained microplastics.


Introducing hidden plastics can be a lot to handle. Remember, it’s better to have millions of people trying to practice zero waste imperfectly than to have a few hundred practicing it perfectly.

Change needs to come from all levels; if you want to see change within your favorite brands, consider sending them an email and calling your local representatives.
