Award-winning — plastic-eating robo-fish is finally here to rid our waters of waste

Award-winning — plastic-eating robo-fish is finally here to rid our waters of waste

via Interesting Engineering

A robot fish that filters microplastics has been created after winning a robotics contest at the University of Surrey.

Researchers in robotics make the “robo-fish” concept a reality, according to a press release published by the University on Thursday.

“Water pollution, especially plastic pollution, is a huge problem. It’s not just the ocean which suffers but rivers, streams, lakes, and ponds. This makes it a problem without a one-size-fits-all solution,” Eleanor Mackintosh, a chemistry undergrad student at the University of Surrey and the contest winner, told New Atlas.

Good news from Antarctica: researchers have examined emperor penguins and found no evidence of microplastics in their stomachs. The study, conducted by the University of Basel and the Alfred-Wegener Institute, is an important assessment of environmental pollution at the South Pole.

Scientists Turn Plastic Into Diamonds In Breakthrough

Scientists Turn Plastic Into Diamonds In Breakthrough

plastic scrapThe production of nanodiamonds from PET plastic paves the way toward a new form of recycling, and even has implications for exoplanets that rain diamonds.

In 2017, researchers in Germany and California found a way to replicate those planetary conditions, fabricating teeny tiny diamonds called nanodiamonds in the lab using polystyrene (aka Styrofoam). Five years later and they’re back at it again, this time using some good ol’ polyethylene terephthalate (PET), according to a study published on Friday in Science Advances. The research has implications not only for our understanding of space, but paves a path toward creating nanodiamonds that are used in a range of contexts out of waste plastic.

Plastic-eating superworms with ‘recycling plant’ in their guts might get a job gobbling up waste

Plastic-eating superworms with ‘recycling plant’ in their guts might get a job gobbling up waste

via SCMP Scientists from Australia’s University of Queensland have discovered that a type of beetle larvae called Zophobas morio can consume and break down polystyrene. Research published in the scientific journal Microbial Genomics on June 9, 2022, says the superworms possess special gut enzymes that can break down plastic. The researchers say they now hope to study the enzymes to engineer ways the substance could be used to break down and dispose of plastic waste in the future.

Microplastic contamination has been reported in beef and pork for the first time, as well as in the blood of cows and pigs on farms.

Scientists at the Vrije Universiteit Amsterdam (VUA) in the Netherlands found the particles in three-quarters of meat and milk products tested and every blood sample in their pilot study.

Scientists unveil bionic robo-fish to remove microplastics from seas

Scientists unveil bionic robo-fish to remove microplastics from seas

via The Guardian

Scientists have designed a tiny robot-fish that is programmed to remove microplastics from seas and oceans by swimming around and adsorbing them on its soft, flexible, self-healing body.

Microplastics are the billions of tiny plastic particles which fragment from the bigger plastic things used every day such as water bottles, car tyres and synthetic T-shirts. They are one of the 21st century’s biggest environmental problems because once they are dispersed into the environment through the breakdown of larger plastics they are very hard to get rid of, making their way into drinking water, produce, and food, harming the environment and animal and human health.

Material Insights: Ukraine crisis drives resin price increases

From Razors to Soda Bottles, Consumer Goods Feel Resin-Cost Burn

via Bloomberg

Booming prices for resins, the building blocks for plastic, have already helped drive up the cost of making everyday products such as toys, bottles and face masks.

Now the fossil-fuel-derived ingredient could get even more expensive as Russia’s attack on Ukraine raises the risk of higher oil prices, potentially trickling down to what consumers pay for household and personal care products. Brent crude had already risen almost 48% in the last year.

Lab turns hard-to-process plastic waste into carbon-capture master

What seems like a win-win for a pair of pressing environmental problems describes a Rice University lab’s newly discovered chemical technique to turn waste plastic into an effective carbon dioxide (CO2) sorbent for industry.

Rice chemist James Tour and co-lead authors Rice alumnus Wala Algozeeb, graduate student Paul Savas and postdoctoral researcher Zhe Yuan reported in the American Chemical Society journal ACS Nano that heating plastic waste in the presence of potassium acetate produced particles with nanometer-scale pores that trap carbon dioxide molecules.
