How plastic manufacturing could be sustainable again

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?

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.

Watch how plastic products are molded from pellets that began as crude oil

Polyethylene and other plastics are formed by combining ethylene and propylene, which are produced through refining crude oil. These plastics are broken down into pellets called nurdles, or mermaid tears, which are melted and molded to manufacture countless products.

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

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 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.

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.

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.

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.

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 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.

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.

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.

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 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.

BPA-free plastics often contain other harmful 'forever chemicals'

These molecules are widely used in single-use plastics, may leach into food, resist breakdown, and can build up in the human body. They have been linked to obesity, heart disease, and neurological issues, particularly when heated.

Multi-material 3D printing produces filament waste if only one nozzle is used

When swapping between colors or materials in a fused deposition modeling system, a considerable amount of filament is purged from the nozzle before introducing a new filament. Filament extruders can create new filament from purged elements, but the device combines colors and produces filaments of inconsistent diameter.
