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.

Most plastic is manufactured from petroleum the end product of a few million years of natural decay of once-living organisms. Petroleum’s main components come from lipids that were first assembled long ago in those organisms’ cells. So the question is, if petroleum-derived plastic comes from biomaterial, why doesn’t it biodegrade?
A crucial manufacturing step turns petroleum into a material unrecognized by the organisms that normally break organic matter down.
Most plastics are derived from propylene, a simple chemical component of petroleum. When heated up in the presence of a catalyst, individual chemical units monomers of propylene link together by forming extremely strong carbon-carbon bonds with each other. This results in polymers long chains of monomers called polypropylene.
“Nature doesn’t make things like that,” said Kenneth Peters, an organic geochemist at Stanford University, “so organisms have never seen that before.”
The organisms that decompose organic matter the ones that start turning your apple brown the instant you cut it open “have evolved over billions of years to attack certain types of bonds that are common in nature,” Peters told Life’s Little Mysteries.
“For example, they can very quickly break down polysaccharides to get sugar. They can chew up wood. But they see a polypropylene with all its carbon-carbon bonds, and they don’t normally break something like that down so there aren’t metabolic pathways to do it,” he said.
But if all you have to do to make propylene subunits turn into polypropylene is heat them up, why doesn’t nature ever build polypropylene molecules?
According to Peters, it’s because the carbon-carbon bonds in polypropylene require too much energy to make, so nature chooses other alternatives for holding together large molecules. “It’s easier for organisms to synthesize peptide bonds than carbon-carbon bonds,” he said. Peptide bonds, which link carbon to nitrogen, are found in proteins and many other organic molecules.
Environmentalists might wonder why plastic manufacturers don’t use peptide bonds to build polymers rather than carbon-carbon bonds, so that they’ll biodegrade rather than lasting forever in a landfill . Unfortunately, while peptide bonds would produce plastics that biodegrade, they would also have a very short shelf life. “It’s an issue of ‘you can’t have your cake and eat it too,'” said Jim Coleman, chief scientist at the US Geological Survey Energy Resources Program. “When you buy a plastic jar of mayonnaise, you want [the jar] to last a few months.” You don’t want it to start decomposing before you’ve finished the mayo inside.

Designer Daan Roosegaarde has installed the “largest smog vacuum cleaner in the world” in Rotterdam to help improve the city’s air quality. The seven-meter-tall structure is designed to create a pocket of clean air in its vicinity, offering a respite from hazardous levels of pollution.
According to the designer, it processes 30,000 cubic meters of air per hour – removing ultra-fine smog particles and pumping out clean air using no more electricity than a water boiler. “The Smog Free Tower produces smog-free bubbles of public space, allowing people to breathe and experience clean air for free,” said a statement from Roosegaarde.

Here is an excerpt from the 2017 APA Mental Health on Climate white-paper:
The ability to process information and make decisions
without being disabled by extreme emotional responses is
threatened by climate change. Some emotional response is
normal, and even negative emotions are a necessary part of
a fulfilling life. In the extreme case, however, they can interfere
with our ability to think rationally, plan our behavior, and
consider alternative actions. An extreme weather event can
be a source of trauma, and the experience can cause
disabling emotions. More subtle and indirect effects of
climate change can add stress to people’s lives in varying
degrees. Whether experienced indirectly or directly, stressors
to our climate translate into impaired mental health that can
result in depression and anxiety (USGCRP, 2016). Although
everyone is able to cope with a certain amount of stress,
the accumulated effects of compound stress can tip a
person from mentally healthy to mentally ill. Even uncertainty
can be a source of stress and a risk factor for psychological
distress (Greco & Roger, 2003). People can be negatively
affected by hearing about the negative experiences of
others, and by fears—founded or unfounded—about their
own potential vulnerability.
PHYSICAL HEALTH AND MENTAL HEALTH
Compromised physical health can be a source of stress
that threatens psychological well-being. Conversely, mental
health problems can also threaten physical health, for
example, by changing patterns of sleep, eating, or exercise
and by reducing immune system function.
Although residents’ mental and physical health affect
communities, the impacts of climate on community health
can have a particularly strong effect on community fabric
and interpersonal relationships. Altered environmental
conditions due to climate change can shift the opportunities
people have for social interaction, the ways in which they
relate to each other, and their connections to the

With over 23 million trees planted since 1984, Plant With Purpose programs and activities are designed to foster long-term impact by equipping families to use their own God-given abilities to address the problems they face. Through an integrated approach to community development, they work to get at the roots of three facets of poverty—environmental, economic, and spiritual.
How is this possible? Plant With Purpose’s programs help families to increase farm yields, heal damaged ecosystems, improve nutrition, increase household savings, and provide greater economic opportunity. Combined, this integrated program solves two major issues facing the world today: environmental degradation and rural poverty.
There are a variety of ways to get involved with Plant With Purpose including sponsorship, internships, fellowships and volunteering. Visit their website: https://www.plantwithpurpose.org/ to learn more about how you can get involved!
As posted in the MIT Technology Review earlier this year, we are developing a new “hot solar cell” technology.
By converting heat to focused beams of light, a new solar device could create cheap and continuous power.
Solar panels cover a growing number of rooftops, but even decades after they were first developed, the slabs of silicon remain bulky, expensive, and inefficient. Fundamental limitations prevent these conventional photovoltaics from absorbing more than a fraction of the energy in sunlight.
But a team of MIT scientists has built a different sort of solar energy device that uses inventive engineering and advances in materials science to capture far more of the sun’s energy. The trick is to first turn sunlight into heat and then convert it back into light, but now focused within the spectrum that solar cells can use. While various researchers have been working for years on so-called solar thermophotovoltaics, the MIT device is the first one to absorb more energy than its photovoltaic cell alone, demonstrating that the approach could dramatically increase efficiency.

Until now. Beginning in 2015, a pair of Google Street View cars, equipped with high tech “mobile labs” developed by San Francisco–based startup Aclima, crisscrossed the streets of West Oakland taking second-by-second samples of the area’s air. They tested for nitrogen dioxide and a type of pollution known as black carbon (bad for your heart and lungs, not to mention the planet), as well as nitric oxide. The cars hit every stretch of pavement, from tiny cul-de-sacs to truck-choked Peralta Street, multiple times, taking millions of measurements.
There are three stationary air pollution monitors for all of Oakland, which reveal the city’s air quality as a whole. But the Street View cars can tell you what the air is like at, say, the corner of Market Street and Grand Avenue—basically anywhere you can drive a Street View car. They can even tell you how the air varies from one end of a single block to the other for a truly hi-res view of the problem.The result: one of the largest and most granular data sets of urban air pollution ever assembled in the world.
Quoting Google’s interview on Aclima: “We visited each block on between 20 and 50 different days over the course of a year,” says Joshua Apte, an engineering professor at the University of Texas at Austin. In the process, they were able to identify patterns they wouldn’t have otherwise seen. “If pollution spikes for an instant, it may or may not be such a bad thing. But if pollution is consistently high, that’s something we really should care about.”
Imagine what difference awareness on air pollution can make when this information becomes more accessible!
