A Practical Guide to Reducing Microplastics and Starting a Plastic Detox at Home
If you zoom in closely enough, plastic shows up in places most of us never expected. Over the past decade, scientists studying microplastics have made some surprising discoveries. Tiny plastic fragments have been detected in Arctic snow, deep ocean trenches, remote mountain peaks, and even in human tissues. If you’re interested in deep diving into how plastics have become so widespread in our environment, the new Netflix documentary Plastic Detox, premiering March 16th, takes a closer look at the issue.
At first thought, the amount of plastic presence sounds pretty unsettling. BUT what it actually reflects is the fact that plastic has become one of the most widely used materials on Earth. For more than half a century it has been woven into nearly every part of modern life from packaging to clothing (yes polyester is plastic!) to household products, building materials, transportation, electronics, etc. Once you understand that scale, it becomes much easier to see how small plastic particles are appearing in unexpected places and how we can make small shifts to avoid them. If we stop buying plastics, the production ultimately decreases Thankfully, the number of high performing alternatives is increasing rapidly.
What Are Microplastics?
Microplastics are simply very small fragments of plastic, typically smaller than 5 millimeters- about the size of a sesame seed or smaller and many are invisible to the naked eye. They form in two main ways. The first comes from everyday plastic products that slowly break down over time. Sunlight, friction, water, and normal wear gradually fragment materials like packaging, synthetic fabrics, plastic bags, dish sponges, cooking utensils, brooms, etc. into smaller and smaller pieces which we end up inhaling or ingesting.
The second source includes plastics intentionally manufactured to be tiny. These were once widely used in cosmetics, toothpastes, and exfoliating scrubs as microbeads. Many countries have since banned them once their environmental impact became clear. Researchers are now paying particular attention to nanoplastics, which are even smaller particles measured in micrometers or nanometers.
They are often released during everyday activities, especially with something as simple as washing dishes or preparing food. Conventional dish sponges and many kitchen utensils are made from plastic materials that slowly wear down with use, shedding microscopic fragments into the water. These particles can also enter food and drinks when they come into contact with plastic. Because they are so small, many are difficult for modern filtration systems to fully remove, allowing them to continue circulating through waterways and, eventually, our water supply.
The important takeaway is that microplastics are not a single product or material. They are the result of plastic’s long life cycle (in some cases centuries), breaking down gradually over time. For that reason, many people have started looking for alternatives made from plant-based materials- but of course no one wants to sacrifice efficacy and luckily we no longer have to as eco-friendly brands continue to rise.
Where Scientists Are Finding Microplastics
One widely cited global analysis from the World Wide Fund for Nature, conducted by researchers at the University of Newcastle, estimated that people could ingest up to about 5 grams of microplastics per week through food, drinking water, and airborne particles- roughly the weight of a credit card. These particles enter the body through everyday exposure: drinking water, seafood, salt, household dust, and the air we breathe. While scientists are still refining these estimates and studying what they mean for human health, the research highlights just how widely plastic has spread through modern environments.

Those numbers can sound abstract because the particles themselves are microscopic. But the important context is that these fragments come from the same plastics used throughout our daily lives. Which means reducing exposure often starts with replacing the products that shed them most easily.
An often overlooked place where plastic commonly leeches from is aluminum cans. They may look like pure metal, but nearly all of them are lined with a very thin plastic-based coating on the inside. This lining is used to prevent the metal from reacting with the food or beverage it holds and to stop the contents from taking on a metallic taste. These coatings are typically made from epoxy or other polymer resins that act as a protective barrier between the aluminum and the drink. While the layer is extremely thin and serves an important purpose for food safety and shelf stability, it is another example of how plastic materials are quietly built into many everyday products- even ones we might assume are entirely safe.
Microplastics in the Air Around Us
Plastic particles are not just found in water and food. They also circulate through the air. Synthetic textiles, carpets, upholstery, packaging materials, and tire wear all release tiny fibers as they age. These fibers become part of everyday household dust and can move through indoor and outdoor air currents.
Traditional plastic brooms, for example, are typically made with nylon or polypropylene bristles. As they sweep across floors and surfaces, these bristles can shed tiny plastic fibers that become part of household dust and the air inside our homes. While the amount released during any single use is small, these materials are used daily and eventually wear out. For those looking to reduce plastic in their cleaning routine, switching to a traditional corn broom (like this one from Lehmans.com) made from natural corn fibers is a simple alternative. Many small businesses and heritage broom makers still produce durable corn brooms that sweep just as effectively without introducing synthetic fibers into the home.

What Scientists Are Studying About Health
Scientists are only beginning to understand what happens when tiny plastic particles interact with the human body. For decades plastic was studied mainly as an environmental issue — floating in oceans or washing up on beaches. But in recent years researchers have started asking a different question: what happens when those same particles make their way into us?
Early studies suggest microplastics may trigger certain biological responses. Some laboratory and animal research has found that plastic particles can cause inflammation and oxidative stress- a type of cellular imbalance that researchers often study in connection with aging and chronic disease. Other studies are exploring whether long-term exposure could influence the gut microbiome, reproductive health, or cardiovascular systems. In one recent study, microplastics were even detected in arterial plaque collected during heart surgery, raising new questions about how these particles move through the body.
At the same time, scientists are careful to emphasize that this field of research is still evolving. Researchers are still working to understand how much of the plastic we encounter actually accumulates in human tissues, how long it stays there, and what levels might matter most for long-term health. New technologies are only recently making it possible to detect particles this small, which means much of the science is still unfolding.
What researchers generally agree on is fairly straightforward: because plastic exposure is so widespread, reducing avoidable sources where practical alternatives exist is a sensible and proactive step.

The Encouraging Part: Many Sources Are Easy to Change
Microplastics might sound like a complex environmental issue, but in many ways the story comes down to simple daily habits. Many of the products that shed plastic particles are things we use every day without giving them much thought. The good news is that once you start noticing them, it becomes surprisingly easy to make small upgrades. More and more companies are creating practical alternatives that fit right into the routines we already have.

The kitchen sink is one of the most frequently used areas in any home and switching to plant-based cleaning tools can be one of the easiest changes to make. Traditional synthetic sponges are often made from petroleum-based plastic foam and/or chemically dyed cellulose. Plant-based, plastic-free cellulose alternatives have come a long way and now can provide an even better cleaning performance while avoiding the plastic materials that can break down into microplastic fragments. One of the biggest problems with biodegradable sponges have been durability and these last a shockingly long time.
Brands like Scrub Be Love have recognized the importance of durable, biodegradable plastic free dish sponges and are helping lead the shift toward simple, everyday environmental swaps.

Starting Your Plastic Detox at Home
Plastic production has grown at an extraordinary pace over the past seventy years. In 1950, the entire world produced only about 2 million metric tons of plastic per year. Today, global production exceeds 450 million metric tons annually, meaning plastic manufacturing has increased more than 200-fold within a single lifetime. Understanding how quickly plastic production has expanded helps explain why microplastics are now being detected almost everywhere scientists look. Source:
