Ocean plastics

The Ocean Cleanup has announced a second Indonesian river trash removal mission. The solar-powered Interceptor 020 will prevent around 1,000 tons of plastic waste flowing into the Java Sea each year from the Cisadane River.

The flapping motion of a new robotic jellyfish is not only good for propulsion, but it can also draw small bits of debris up from the ocean floor without contact. Such a robot could remove trash from delicate ocean environments, like coral reefs.

The amount of single-use plastics the world disposed of during the pandemic continues to be a huge environmental headache. A clever new upcycling method, though, takes the trash and turns it into one increasingly lucrative piece of tech, carbon dots.

Scientists have described a new disease called plasticosis, caused by – you guessed it – plastic waste. So far it's only been identified in the digestive tracts of seabirds, but the scale of the problem suggests it could be widespread in other species.

The Ocean Cleanup has a huge task on its hands in ridding the seas of plastic waste, but a new video offers a compelling look at its latest plan of attack, portraying massive trash-collection barriers sweeping through the seas with great efficiency.

We already know that waterborne plastic particles can enter the bodies of fish, which are then eaten by humans. New research, however, shows that such particles can enter the food chain via another route, by traveling from plants to insects to fish.

Marine plastic pollution is a big problem, as exemplified by the Great Pacific Garbage Patch. According to a study conducted by the Ocean Cleanup project and Wageningen University, most of the plastic in that patch comes from the fishing industry.

Although there's no doubt that marine plastic waste pollution is a major problem, there may be at least a small sliver of hope. According to a new study, plastic trash on Australian beaches has actually decreased by almost a third in recent years.

Tentsile has built an impressive stable of suspended sleeping shelters and hammocks since launching its very first tree tent in 2012, and its latest creations land with a particularly green tinge through the use of recycled ocean plastics.

Back in 2020, Open Ocean Engineering launched an autonomous vessel designed to clear plastic waste from local waterways. After partnering with Razer last year for a radical redesign, a sleeker Clearbot has now started patrolling Hong Kong waters.

The way plastic moves through the environment is of great concern to scientists, and a first-of-a-kind study has unearthed disconcerting new information on how microplastics can carry pathogens far out to sea and endanger marine life.

Marine debris is a huge problem, both when it's floating at sea and when it gets washed up on the shore. In order to locate the latter for removal, scientists are developing AI-enabled drones which will spot human-made beach trash from the air.
