How existing technology could prevent nearly 80% of plastic pollution

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Invasive species are the third biggest threat to Earth's biodiversity

According to the World Wildlife Fund's Living Planet Report 2020, changes in land and sea use account for about half of all recorded threats to the diversity of the planet's species. Species overexploitation is the second-largest proportional threat at 24%, while invasive species make up 13%.

What happens if you throw trash into lava?
