Here's how the seven types of plastics fare in the recycling process

To help you make better-informed decisions about the products that you buy, here's a simple explanation of the seven different types of plastic, how they differ, and their impact on the environment.

A step-by-step guide to the plastic recycling process

Everything you wanted to know about how plastic is recycled, the companies that collect and recycle plastic, where you can recycle, and much more.

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.

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

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.

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.

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

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?

BPA-free plastics may still pose health risks because they often contain other structurally similar chemicals.

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.

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.

The amount of plastic chemicals in 300 everyday Bay Area foods

Food production is more complicated than it appears, and manufacturing, packaging, and shipping processes can add significant substances to your food. This massive project compiled data on 300 samples of foods delivered to the San Francisco area, testing for the presence of 18 different kind of plastic. Learn how to read the data here with its helpful guides and then explore the table yourself.

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.

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.

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.

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 plastics industry spent decades promoting recycling while privately doubting it would ever work

This FRONTLINE investigation reveals that plastic makers publicly championed recycling for years despite internal doubts about its viability, and that no more than 10% of the plastic ever produced has been recycled.

Many plastic products are molded from melted pellets called nurdles, which are made from ethylene and propylene extracted from crude oil.

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.

A guide to single-use plastic bans across the US

Over 100 cities and municipalities in the US have banned Expanded Polystyrene (EPS) in government facilities including New York City, Los Angeles, Seattle, San Diego and Miami Beach, Florida. Here, maps illustrate what US states have bans in place.

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.

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.

Microplastics 101: What we know about the contaminants invading our bodies

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.

Visualizing the enormity of plastic waste compared to global landmarks

The team at Reuters Graphics visualizes the world’s addiction to plastic bottles. Around the world, almost 1 million plastic bottles are purchased every minute. The illustrations included in this visual explainer show what that pile of plastic would look like if it was collected over longer periods of time and how large the piles would be compared to famous landmarks.

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.

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.

How disruptions in oil markets can drive up the price of everyday goods

Most types of plastic are made from polymers derived from chemicals produced by the processing and refining of crude oil and natural gas. Spikes in the cost of either fossil fuel raise the cost of wrappings, tubs, and other plastic containers for products.

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.

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.

How Big Oil misled the public into believing plastic would be recycled

An NPR and PBS Frontline investigation reveals how the oil and gas industry used the promise of recycling to sell more plastic, even when they knew it would never work on a large scale.

How billiard balls catalyzed the 'Plastics Century'

For centuries, billiard balls were made of ivory from elephant tusks. But when excessive hunting caused elephant populations to decline, they began to look for alternatives: celluloid, which would become known as the first plastic.

Plastic's history began with an inventor seeking a $10,000 prize offer

In 1869, the first synthetic polymer—celluloid—was created as a substitute for ivory in billiard balls. It became the historical catalyst for the eventual manufacturing of plastics everywhere as an alternative to the depletion of other natural resources, including tortoiseshell and horns.

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

Countries tried to curb plastic waste, but the US keeps shipping more

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.

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.

After swallowing 23 pieces of plastic, seabirds experience a 90% death rate

Researchers found that this threshold is also met when marine mammals ingest 29 pieces and when sea turtles consume approximately 405 pieces. Almost half of the sea turtles, a third of the seabirds, and one in ten of the marine mammals studied had eaten plastic.

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.

View a sample of objects surprisingly derived from crude oil, including chewing gum and lipstick

Crude oil processing produces a variety of fuels and the building blocks for plastics, but it also distills out the hydrocarbons used to make aspirin, Teflon, vinyl, crayons, candles, Tupperware, roofing shingles, asphalt pavement, hair dye, anesthetics, food-grade lubricants, polyester, synthetic rubber, and resins for items like dentures.
