What to do about the microplastics in your laundry

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

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.

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.

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

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

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.

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

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.

A guide to avoiding single-use plastics

Here’s everything you need to know about the most ubiquitous (and avoidable) kind of plastic waste: single-use plastics, the kind made to be tossed in mere minutes

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.

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

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.

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

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.

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.

A UN-led treaty may establish rules to phase out plastic globally

With support from more than 175 nations, a treaty led by the United Nations is being negotiated to establish enforceable global rules for plastic production and pollution by 2025. Negotiations come as the total amount of plastic in the ocean has increased by 50% from 2017 to 2022.

Removing trash from the oceans not only saves wildlife, it may save human lives, too. The CEO and founder of The Ocean Cleanup explains how existing plastic pollution harms us and get harder to clean up over time.

Where the US's plastic recycling is discarded

The US ships over a million tons of plastic waste overseas each year. A short video explainer from USA Today shows a breakdown of what really happens to America's recyclables.

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.

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.

How chemical recycling could create 'infinite' plastic

The way we normally recycle plastics is a downward spiral of waste and degraded materials, but there is another option—turning plastic back into the oil it was made from.

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.

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

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.

Explore the UN’s interactive guide to global plastic pollution

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.

The global plastic crisis in images

For decades we have relied on plastics to keep us safe, insulate our homes, and make sure our food stays fresh. But when does plastic's life come to an end?

The harsh realities of the Great Pacific Garbage Patch

Misleading images and narratives have caused the public to believe that the Great Pacific Garbage Patch is simply a large clump of floating trash in the ocean. Instead, a more apt description would paint it as a dispersed "soup of microplastics" that severely impacts marine life and the fishing industry. Read for a greater understanding of how the GPGP came to be, and the measures that need to be taken for a cleanup.

Japanese scientists have developed an eco-friendly plastic that naturally dissolves in hours, leaving behind molecules containing phosphorus and nitrogen, which fertilize soil.

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.

Data show that American exporters continue to ship plastic waste overseas, often to poorer countries, even though most of the world has agreed to not accept it.

Most biodegradable plastics don’t break down in everyday conditions

Despite their eco-friendly name, biodegradable plastics often require industrial composting, which most areas lack, to decompose the uncommon compounds found in them. This means they may linger in landfills or contaminate conventional plastics in recycling bins.

The history of natural and synthetic plastics

From cheap toys to woolly jumpers, plastic can be found in more products than many people realize. From a chemist's perspective all these things are made of the same class of materials: Polymers. And the distinction between which ones we happen to call "plastics" and which ones we don't is fairly arbitrary.
