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.

A hard truth to swallow, but according to Rozalia Project, we are eating our fleece! Rozalia Project has developed the Cora Ball microfiber catcher, the first human-scale, consumer solution to synthetic microfiber pollution in our ocean, lakes and rivers. Check out their successful Kickstarter Campaign here: https://www.kickstarter.com/projects/879498424/cora-ball-microfiber-catching-laundry-ball
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.

Let us welcome the “OBRIST C-Transformer.” It is a machine that founder Frank Obrist says “will help nature do what nature does best. Just a little bit faster. For our future.”
Although the machine is in prototype, the team has offered details on how it will operate: “Navigating through the forest, the OBRIST C-Transformer will char trunks of old trees and dig the biochar into the forest soil, binding its carbon. This very fertile soil will become the nursery for fresh tree seeds to that new vegetation can immediately start to grow. It will also have the capability to plant new trees within the fertile soil that is created.
Obrist has stated that they work closely with permaculture experts and scientists who continuously make sure that the natural balance of the environment is maintained. He says they also use a “thrice-conducted spiral route” for the OBRIST C-Transformer that will ensure every area will only be prepared and processed once every 45 years. They offer a video explanation and further details to answer some of our immediate questions.
Go through their “choose-your-own-adventure” style FAQ section and start the conversation by sharing your ideas! They are openly admitting that there are some issues still needing to be resolved. You can also check out input from other people.

A UK-based team of researchers has created a graphene-based sieve capable of removing salt from seawater.
The sought-after development could aid the millions of people without ready access to clean drinking water.
The promising graphene oxide sieve could be highly efficient at filtering salts, and will now be tested against existing desalination membranes.
It has previously been difficult to manufacture graphene-based barriers on an industrial scale.
Reporting their results in the journal Nature Nanotechnology, scientists from the University of Manchester, led by Dr Rahul Nair, show how they solved some of the challenges by using a chemical derivative called graphene oxide.
Isolated and characterised by a University of Manchester-led team in 2004, graphene comprises a single layer of carbon atoms arranged in a hexagonal lattice. Its unusual properties, such as extraordinary tensile strength and electrical conductivity, have earmarked it as one of the most promising materials for future applications.
But it has been difficult to produce large quantities of single-layer graphene using existing methods, such as chemical vapour deposition (CVD). Current production routes are also quite costly.
On the other hand, said Dr Nair, “graphene oxide can be produced by simple oxidation in the lab”.
He told BBC News: “As an ink or solution, we can compose it on a substrate or porous material. Then we can use it as a membrane.
“In terms of scalability and the cost of the material, graphene oxide has a potential advantage over single-layered graphene.”

In the race to find solutions to critical water issues, the launch of a new cost-effective water quality sensor device by Beacon Institute for Rivers and Estuaries|Clarkson University is the first step in overcoming hurdles of historically prohibitive costs for long-term water resource monitoring.
The installation of the Institute’s newest generation of River and Estuary Observatory Network (REON II) sensor arrays signifies the passing of the baton from the science lab to the river as they run ahead, complementing government capacity to invest in “wiring” the river for cleaner water.
The REON II device or “Sonde,” deployed on the banks of the Hudson River in New Hamburg, N.Y., is providing real-time data called for by scientists to better understand the complex relationship between humans, the built environment and our fragile waterways.
It is one of 37 sensor stations currently in place in the Hudson and St. Lawrence river watersheds, making REON one of the world’s most robust resources of real-time data. The goal of the REON research team to develop affordable, scalable, low-profile sensor networks and its potential for making water sensor technology universal, could be transformational to the field of environmental science.
CEF FFT: The more up-to-date and accurate the data we can collect on the water quality of rivers and estuaries, the more we can become aware of the impact our civilization has on these precious sources of life.

Founded by Richard Hardiman, Ranmarine Technology uses WasteShark — 24-hour on-the-water drones. The solar-powered drones collect detritus, marine waste and chemical substances from ports and canals.
Founded in 2015 in South Africa, the company was later re-incorporated in the Netherlands at the start of last year as RanMarine Technology BV.
Hardiman is based in Rotterdam. He moved there after being selected for PortXL Rotterdam’s maritime accelerator (portxl.org) in February last year. The startup was one of 12 companies selected from 1000 startups worldwide.
In July last year the startup began a pilot with the Port of Rotterdam to test both the use of autonomous surface vessels in their waters and how the product actually works in “high trafficked waters”. The pilot was successfully completed last month.
There are currently 3 different types of the Waste Shark products: the WasteShark, the Great WasteShark and the ChemShark.

Combining Quebec’s expertise in hydroelectricity, aluminum and renewable energy, Idénergie has successfully developed the first solution to easily generate electricity from the natural flow of a river. This innovation will allow people to generate electricity from nearby rivers, 24 hours a day.
Idénergie’s river turbine has an embedded smart converter that allows the conversion of the energy harnessed from the water current into electricity. The built-in smart converter includes many additional features including a self-starting turbine, continuous power optimization, remote monitoring capabilities, an emergency brake and many more to come.
Mostly made of noble metals such as aluminium and other environmentally friendly components, the turbine is the greenest amongst all available renewable energy products. These material do not react to the environment and are easily recyclable ensuring a substantial end of life value. In addition, the river turbine does not require a permanent structure reducing its impact on aquatic fauna.
By taking into account numerous studies estimating the interactions of the turbines with the ecosystems, Idénergie designed its product in order for it to have minimal impact on the aquatic fauna and its housing environment. Studies carried out by the Alden laboratories, an american entity, have proven that the Darrieus Turbines, used by Idenergie, represent no harm to the river’s ecosystem. In fact, extracting energy from a fluid tend to slow it down, resulting in faster velocity on the side of the turbine thus floating objects and debris, as well as fish, tend to naturally avoid the turbine resulting in 98% survival rate.
A society based on a green economy is Idénergie’s dream. Fully aware of the need to adapt to the threat of climate change, they aim to make a positive difference by encouraging every individual, homeowner or community to use renewable energy and become energy-independent.
Check out their website http://idenergie.ca/en/ to see how this renewable-energy hardware is accessible and discover how yes, it can be done.

The world’s first solar-powered train is here!
India’s first solar-powered trains has begun service, running a 12.5-mile route from Delhi’s Safdarjung station to Farukh Nagar in the country’s north. The diesel-electric hybrid train has six coach cars with solar panels embedded in their roofs. The panels feed a battery that can power the train for up to 72 hours. Roughly 50 solar-harvesting coaches are set to be launched in the next several days, running primarily along commuter routes.
The new trains are a part of Indian Railways’s plan to establish an energy-generation capacity of 1 gigawatt of solar and 130 megawatts of wind power in the next five years. The state-owned company has been using train-mounted solar panels since 2015 to power interior lights and air conditioning, but their newest train is the first in the world to use solar power.
India isn’t the only country exploring solar-powered trains. A research team at the Imperial College London is embarking on a similar quest to take trains off-grid and power them with solar energy. However, the UK project is looking to track-side solar panels, not ones directly mounted to the trains themselves.
