During wash cycles, synthetic fabrics shed millions of plastic microfibers, making them a significant source of global microfiber pollution.

What to do about the microplastics in your laundry

Synthetic fabrics shed millions of tons of microplastics into oceans each year, largely through laundry wastewater. Here are ways to reduce the pollution.

Synthetic textiles and tires account for more than 60% of ocean microplastic pollution, which enters the seas via runoff and wastewater discharge.

Research shows that over 1,000 metric tons of microplastics fall on national parks every year—equivalent to 120 million bottles of water.

Microplastics have been found everywhere there is liquid or vapor water, from the oceans and tropical waters to polar ice and the air we breathe, posing growing risks to wildlife and ecosystems.

The prevalence of microplastics came from plastic’s affordability and versatility

Microplastics' durability and overuse have led to massive pollution that overwhelms the planet's ecosystems. Avian, terrestrial, and marine life have been observed to contain microplastics in their bodies, but reverting to paper, cotton, and other materials in manufacturing also brings environmental challenges.

Microfiber cloths have four times as much surface area as similarly sized cotton, enabling them to more effectively trap dirt and oil.

View the estimated decomposition times for various everyday plastic products, which often fragment into smaller microplastics as molecular bonds are weakened by sunlight.

Microplastics are entering human food chains through carrots, wheat, and other foodstuffs grown in farmlands fertilized by sewage sludge.

To reduce wrinkles in clothing, research recommends gentle wash cycles with more water and tumble drying with smaller loads and longer times.

Laundry detergents designed for cold-water washes rely on proteins isolated from microorganisms native to cold climates, such as Iceland.

In Indonesia, microplastics rain down when trash is burned, and people may ingest the equivalent of 3 credit cards per month—on average.

Microplastics have been found across all of Earth's depths and altitudes, from plastic debris in the Mariana Trench to fragments found in snow samples near the summit of Mount Everest.

Microplastics are infiltrating the human body with unclear but concerning effects

Scientists have linked microplastics to immune system damage, hormone disruption, inflammatory diseases, and even cancer—yet most of their health impacts remain unknown due to limited research. Studies suggest we ingest about a credit card's worth of plastic weekly.

Conditioners can help unshrink garments by lubricating fibers

Textile fibers relax and shrink due to heat and moisture, disrupting hydrogen bonds. While loosely knitted fabrics are more prone to shrinkage than tightly woven ones, synthetic fibres like polyester resist shrinkage due to their crystalline structure.

Some algae have helped remove microplastics from water after being bioengineered to clump together with these contaminants, forming an easily collectible microplastic-algae sludge.

The challenges of trying to study microplastics in microplastic-abundant labs

The presence of microplastics in instruments, surfaces, and air has made accurate measurement of their levels in lab samples difficult, given the high likelihood of contamination. While the use of stainless steel tools in a sealed, clean lab may reduce accidental exposure, existing methods can misidentify biological substances, such as fat, as plastics, further complicating research.

Scientists have found that sewage sludge used as fertilizer introduces various microplastics into soil, which persist in farmland for decades.

From soil to beer, microplastic pollution is all around us

Marine plastic pollution has been studied for decades, but the extent and effects of plastic pollution elsewhere is only just beginning to be explored.

When diving and snorkeling in environments containing reefs, avoid touching reefs, anchoring on them, or using sunscreen with active ingredients harmful to marine life.

Fifty-one trillion particles of microplastics float in our oceans. Yet there is very little science of how this affects our health. This quick 2-minute video explains the dangers of microplastics.

How existing technology could prevent nearly 80% of plastic pollution

More than 28 million tons of plastic enters the environment each year, where it harms animals and damages habitats. A study co-authored by researchers at The Pew Charitable Trusts found that this flow can be reduced by nearly 80% in the next 20 years using existing waste management and recycling technology.

Microplastics have been identified across human body systems, with research finding they are most commonly ingested through inhalation, drinking water, and diet before crossing barriers into organs.

How plastic manufacturing could be sustainable again

From polymers to nurdles, learn how plastic is created and what we can do to slow the lasting repercussions this material will have on both our planet and our lives.

Research suggests microplastics disrupt photosynthesis in plants and algae, and this damage in crops may already rival the impact of climate change on food supplies.

Mermaid tears are a long-lasting and hazardous form of ocean microplastic pollution, whose chemical composition enables them to contain higher concentrations of certain toxins than the surrounding environment.

As of 2025, the FDA states that microplastics have not yet been shown to pose a risk to human health, though it acknowledges that evidence suggests microplastics and nanoplastics have entered the food supply.

There's a fast fashion graveyard in Chile's Atacama Desert full of used clothing from the US, Europe, and Asia.

Despite being derived from crude oil, which itself comes from organic material, synthetic plastic isn't biodegradable because it hasn't existed long enough for microbes to have developed mechanisms to break it down.

Research shows that microplastics and nanoplastics can accumulate in major arteries, and patients with these deposits are significantly more likely to suffer heart attacks, strokes, or death.

As of 2023, more than 130 nations have enacted bans or restrictions on plastic items, starting with Bangladesh's ban on plastic bags in 2002.

Within fabrication plants, it takes about three months to manufacture hundreds of microchips from a single wafer of pure silicon using light and significant quantities of electricity, water, and hazardous chemicals.

What percentage of the world’s plastic waste actually gets recycled?

Despite growing awareness of the world’s plastic waste challenges, the numbers showing how much of the world’s plastic waste actually gets recycled are abysmal. Only 9% of the world’s plastic waste is properly recycled, and a significant portion remains landfilled, mismanaged, or incinerated. Read this article for further analysis of why this is and what can be done in the future to better manage plastic waste.

Explore the UN’s interactive guide to global plastic pollution

Around the world, 1 million plastic drinking bottles are purchased every minute, while 500 billion single-use plastic bags are used worldwide every year. In total, half of all plastic produced is designed to be used only once—and then thrown away.

Most plastics are not biodegradable because breaking their chemical bonds requires temperatures lethal to most microbes, and these organisms have not been exposed to plastic long enough to evolve the necessary enzymes.

Although PFAS, or forever chemicals, are intentionally designed to be extremely stable and long-lasting because of their strong carbon-fluorine bonds, these bonds can be broken by heat, plasma, and supercritical water.

Why bacterial bioremediation may help counter the negative effects of past chemical solutions

Molecules such as DDT, a synthetic insecticide, and PFAS—"forever" chemicals used to make products resistant to heat, water, and grease—have historically been used across various industries but are now known to be harmful. Microbes that can convert some of these substances into nontoxic products, such as water and carbon dioxide, have already been identified, with ongoing research to find others.

Airborne microplastics may influence cloud formation and climate

Microplastics are increasingly found in the atmosphere and may affect the climate by reflecting or absorbing sunlight based on their pigmentation. Like mineral dust, they may become cloud seeders and alter regional precipitation patterns as they become more abundant.

Thousands of quarters and huge water bills: the economics of laundromats

There are approximately 30,000 laundromats in the US, serving the roughly 50% of apartment dwellers who do not have a washer or dryer. Shops profit when they can get their machines—roughly 30 to 40 per location, on average—to wash eight to 10 loads a day. Connections with commercial vendors help.

The cleanup of oil and other chemical spills involves a combination of methods tailored to different settings, including vacuuming, dispersing absorbent materials, chemicals, or biological agents, and localized burning.
