What to do about the microplastics in your laundry

Washing clothes is a significant source of global microfiber pollution

Synthetic fabrics shed millions of plastic microfibers during washing, which pass through wastewater treatment and end up in oceans, soil, and food chains. A single wash load can release several million microfibers, but washing with cold water can reduce this.

Synthetic textiles and tires are the top sources of secondary ocean microplastics

These sources contribute more than 60% of the primary microplastics polluting the oceans, followed by city dust and road markings. City dust is made of pieces of building coatings, synthetic footwear, and other human-made objects that have broken off due to weathering and abrasion.

Microplastics are everywhere and pose growing risks to wildlife and ecosystems

These tiny plastic particles come from intentionally small items and the breakdown of larger plastic debris, ending up in soil, air, and water. A study of 37 US National Park beaches found microfibers at every site, making up 97% of all microplastic debris.

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

Learn how humans can protect coral reefs

When diving and snorkeling in environments containing reefs, avoid touching reefs, anchoring on them, or using sunscreen with active ingredients harmful to marine life. Properly recycling and disposing of trash in bins helps reduce microplastics and chemicals that can run off into wastewater and into the oceans.

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.

Research has shown that bioengineered algae can help remove microplastics

Scientists at the University of Missouri found that, like microplastics, some algae are particularly hydrophobic—they repel water—and that both can clump together to form a microplastic-algae sludge, which can then be collected to remove microplastics from water. Researchers believe this algae provides a scalable solution for microplastic removal that can be employed in wastewater treatment processes.

Mermaid tears are a lasting and hazardous form of ocean plastic pollution

Also known as nurdles, these tiny plastic pellets are extremely difficult to remove once spilled. Their chemical composition, which enhances absorption, causes them to contain higher concentrations of certain toxins than the surrounding environment.

Microplastics from sewage sludge persist in farmland soil for decades

A 25-year study in Scotland found that sewage sludge used as fertilizer introduces various microplastics into soil, where they remain and degrade into smaller particles that worsen soil quality. Dyes found in microplastics may also be leaching into the environment, causing additional toxic effects.

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

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.

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.

Founder of The Ocean Cleanup explains the case for cleaning oceans

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.

Plastics don’t biodegrade because their chemical bonds are unnatural to microbes

Despite coming from petroleum, which itself comes from organic material, synthetic plastic was not mass-produced until the mid-20th century. Insufficient time has passed for microbes to develop the necessary enzymes to break it down naturally.

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 develop an eco-friendly plastic that dissolves in saltwater

The strong and flexible plastic is made from molecules held together by saltwater-sensitive chemical bonds. The components left after the plastic breaks down within hours contain phosphorus and nitrogen, allowing them to serve as soil fertilizer.

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.

View the steps you can take to stop invasive species

Individuals who are outside should make sure to wash any outdoor gear and equipment with appropriate tools to limit the spread of seeds and other microorganism-carrying debris across locations. Pets, horses, and other animals should be similarly brushed, and firewood should be burned where it is purchased.

Watch how metals are extracted from rechargeable devices during recycling

Recyclable batteries found in cars, phones, power tools, and other electronics contain lithium, cobalt, nickel, and other precious metals, whose reuse generates 70% fewer emissions than during their initial mining. Upon shredding these devices, a filter press squeezes the pieces through a proprietary fluid, which separates them for future reuse.

Scientists have proposed using lasers to push space trash into Earth's atmosphere

Such projects would allow most debris to burn up and no longer pose a risk to active satellites, telescopes, and astronauts on space stations. Enacting these plans would require substantial investments from private and governmental space agencies and overcoming international laws that prevent the removal of another country's space equipment.

The most common type of 3D printer fabricates objects using plastic
