Plastic waste
-
Black plastics pose an ID problem for sorting machines at recycling facilities, as the sensors can't see them. Canon has developed a system that users lasers and tracking tech to identify and sort plastic trash on the conveyor belt, no matter its color.

Marine plastic waste is a huge problem, but the Ocean Cleanup has been taking a bite out of floating trash in oceans and rivers for the last few years. Now Coldplay is about to use some of that waste for a limited edition of its forthcoming album.
-
Clear Robotics is expanding its fleet of autonomous marine trash collectors. Its Class 3 vessel boasts more onboard storage capacity plus towed barge potential for extended cleanup operations, and has also been designed to tackle invasive weeds.

That we have a huge plastic waste problem is clear, but there are numerous efforts to stem the tide while also cleaning up the mess. Nature is also joining the battle, and scientists have now identified a marine fungus at the plastic-devouring front line.

A new biodegradable plastic embedded with spores of plastic-eating bacteria manages to break down 90% of the material after five months in landfill. Weirdly, this actually made the plastic tougher and stronger during use.

Back in 2022, the strange-looking prototype igus:bike rolled into the spotlight boasting an angular frame, funky wheels and even bearings made using recycled plastic. Now the newly-named RCYL bike is riding into production.

Using advanced single-particle imaging technology, researchers have ascertained the number of nanoplastics – plastic fragments smaller than a micrometer – in bottled water, finding that, on average, a liter contains 240,000 detectable fragments.

Though efforts to clean up plastic waste from our oceans are well underway, it's also vital to stem the tide at a major source of pollution: rivers. Researchers in South Korea are looking to doing just that at a "living lab" facility in Gongju.
-
A study has found that plastic additives might be stopping the reproductive habits of a shrimp-like species that is key to the marine food chain. The findings provide a different perspective on the potential damage caused by specific pollutants.

While the use of recycled plastics is normally considered a noble endeavor, a new study says it's time to think twice. In an analysis of the material from more than 10 different countries, hundreds of potentially harmful chemicals were uncovered.
-
UK shipyard MMS has added a new member to its fleet of floating-debris collection vessels. The latest Envirocat is the first to clean up waterways without releasing engine fumes into the environment.

For the first time, scientists have identified a biochemical mechanism linking attention deficit hyperactivity disorder and autism spectrum disorder with common but problematic compound Bisphenol A (BPA), which can leach into food and drink from packaging.
