Scientists have created a method to convert carbon dioxide back into solid coal, a breakthrough that could change the ways carbon is removed from the atmosphere and permanently stored.
It’s one of several recently developed negative emissions techniques that seek to make carbon capture and storage cheaper, safer and more efficient. This particular method was developed by a research team led by RMIT University in Melbourne, Australia, and it uses a liquid metal electrocatalyst, containing nanoparticles of the rare-earth metal cerium, to convert the greenhouse gas into a stable, coal-like solid.
“While we can’t literally turn back time, turning carbon dioxide back into coal and burying it back in the ground is a bit like rewinding the emissions clock,” study co-author Dr. Torben Daeneke told The Independent. “To date, CO2 has only been converted into a solid at extremely high temperatures, making it industrially unviable.”
Tesla’s solar roof is gradually rolling out to more homes. A new set of photos shared this week show a new installation at twilight, complete with cutouts for chimneys and other features. The design looks impressive, and it’s one of the few sightings seen on social media since the first installations appeared early last year.
The roof was shared by a now-deleted Twitter account, which was subsequently posted to Reddit by a user called “Potatochak,” where it received over 3,000 upvotes on the Tesla subreddit. The depicted tiles appear to be the textured variety, but the company also offers a smooth style depending on cosmetic appearance. Tesla recommends a normal house uses a mix of 35 percent solar tiles at $42 per square foot to 65 percent “dummy” tiles at $11 per square foot, resulting in an average price of $21.85 per square foot, but it’s unclear how many times are operational in these images.
Andrew Turton and Pete Ceglinski, two avid surfers, decided to quit their jobs to create a “Seabin” that would collect trash, oil, fuel and detergents.
The Seabin is a floating rubbish bin that is located in the water at marinas, docks, yacht clubs and commercial ports.
The Seabin moves up and down with the range of tide collecting all floating rubbish. Water is sucked in from the surface and passes through a catch bag inside the Seabin, with a submersible water pump capable of displacing 25.000 LPH (litres per hour), plugged directly into 110/220 V outlet. The water is then pumped back into the marina leaving litter and debris trapped in the catch bag to be disposed of properly.
Seabins can skim unsightly surface oils and pollutants. This location shared from @seabin_project had a boat with a fuel leak problem in the marina. Seabins are fitted with oil absorbing pads and it cleaned up the spill in no time.
Who knows what impact this technology could have in helping clean our ports and harbors! Visit their site to get a quote for single or multiple V5 Seabin units at http://seabinproject.com/pre-sales/
Narayana Peesapaty created edible spoons in Hyderabad, India, because he is fed up with plastic waste.
India is in the region of South Asia where it is culturally common to eat traditional meals with your hands, even among the wealthy who can trace the practice back to Ayurvedic teaching—and yet every year Indians use 120 billion pieces of plastic cutlery. Maybe investing in silver cutlery would stop them over-indulging in plastic.
Waste production is particularly problematic in large cities whose economic development precedes waste management infrastructure. China is an example of one of the world’s most densely populated regions that has come to create the world’s largest economy, though their record-breaking growth amounts to unprecedented pollution.
The individual efforts that CapitaLand encourages is something that the earth demands from all of us now. Statistics from the World Economic Forum cite that global plastic production has grown from 15 million tons in 1964 to 311 million tons in 2014- a number that is expected to triple by 2050, unless some sort of radical change takes place.
Peesapaty’s utensils should hasten that change. He began his business, Bakeys, in 2011, though it is gaining larger attention today because the business is crowd-funding with The Better India video to make money for investment in chopsticks and forks.
The edible cutlery is a bio-degradable option that has a shelf life of three years and decomposes within four-five days if not used. They even come in three different flavors to suit the food that they are served with: plain, sweet, or spicy.

Scientists have created a mutant enzyme that breaks down plastic drinks bottles – by accident as posted in the Guardian recently on April 16th! The breakthrough could help solve the global plastic pollution crisis by enabling for the first time the full recycling of bottles.
The new research was spurred by the discovery in 2016 of the first bacterium that had naturally evolved to eat plastic, at a waste dump in Japan. Scientists have now revealed the detailed structure of the crucial enzyme produced by the bug.
The international team then tweaked the enzyme to see how it had evolved, but tests showed they had inadvertently made the molecule even better at breaking down the PET (polyethylene terephthalate) plastic used for soft drink bottles. “What actually turned out was we improved the enzyme, which was a bit of a shock,” said Prof John McGeehan, at the University of Portsmouth, UK, who led the research. “It’s great and a real finding.”
The mutant enzyme takes a few days to start breaking down the plastic – far faster than the centuries it takes in the oceans. But the researchers are optimistic this can be speeded up even further and become a viable large-scale process.
“What we are hoping to do is use this enzyme to turn this plastic back into its original components, so we can literally recycle it back to plastic,” said McGeehan. “It means we won’t need to dig up any more oil and, fundamentally, it should reduce the amount of plastic in the environment.”
About 1m plastic bottles are sold each minute around the globe and, with just 14% recycled, many end up in the oceans where they have polluted even the remotest parts, harming marine life and potentially people who eat seafood. “It is incredibly resistant to degradation. Some of those images are horrific,” said McGeehan. “It is one of these wonder materials that has been made a little bit too well.”

Based out of the waterfront partnership of Baltimore, Maryland and going by the name “Professor & Mr. Trash Wheel” these devices are vacuuming plastic from our oceans much like a Roomba for waterways. They operate exclusively on the energy they get from sunlight and water. Collecting litter and debris, keeping trash from winding up in the ocean, the device uses two trash containment booms in order to direct the waste up a conveyor belt and into the dumpster barge on the other end.
Since being installed, the trash wheels have kept over one millions pounds of litter out of the Atlantic ocean!

A startup in India is capturing the black particles that float in air pollution and turning them into ink.
Anirudh Sharma was at a conference in India when he noticed black particles accumulating on his white shirt. The specks settling on him were from pollution in the surrounding air.
Byproducts from burning fossil fuels such as gasoline and coal are causing health problems and climate effects around the world, especially in India’s growing cities. In that moment a few years ago, though, Sharma saw the pollution particles as something simpler: A coloring agent.
He went back to MIT Media Lab in Cambridge, Massachusetts, where he was a graduate student focused on augmented reality, and began working on an idea to turn carbon pollution into ink. Using candle soot to start, he came up with a prototype. After finishing his master’s degree, he went back to India and in 2016 co-founded a collaborative called Graviky Labs to continue working on Air-Ink and other ideas.
They developed a device that can be fitted onto the exhaust pipe of a car or portable generator and collected the soot that forms from burning diesel fuel. By mixing the fine black powder with solvents, they produced ink that then went into bottles and markers.
Kaushik says Air-Ink has a dual benefit: “It’s not just that we’re recycling that material into inks. What we are also doing is replacing the carbon black that otherwise would have been used to make black inks.” Manufacturers typically use the soot known as carbon black in rubber, ink, paints, and carbon paper.
After posting their endeavor on Kickstarter earlier this year, the team brought in $41,000—nearly three times the donations they sought to start producing Air-Ink in larger quantities. Through a sponsorship from a beer company, they’d already begun distributing the ink to artists, who created public pieces in London, Singapore, and other cities.

The single biggest pollution problem facing our ocean is microfiber: trillions of pieces of tiny fibers flowing into the ocean – every time we use our washing machines. Our clothing is breaking up, sending this microfiber (made of plastic and chemical-covered non-plastics) out with the drain water – just one fleece jacket could shed up to 250,000 pieces per garment per wash [source]. New York City, alone, could have 6.8 billion microfibers flowing into its harbor every day. We are all contributing to this problem.
