The building in the background of the photo above has never featured in any of our architecture-focused posts before, even though architecture has been a key theme since our start, and especially after hosting these interns in India. I know why I never wanted that particular architect in our pages, but nevermind that. This post is about another architect’s achievement, which I plan to visit if I get close enough before December:

SHIGERU BAN: THE PAPER LOG HOUSE

The Glass House, Shigeru Ban Architects (SBA), and The Irwin S. Chanin School of Architecture of The Cooper Union announce the completion of Shigeru Ban: The Paper Log House at The Glass House. Students from The Cooper Union joined in erecting the structure through a unique opportunity offered this semester for the university’s Building Technology course. The collaborative installation will be on display April 15th through December 15th 2024 for The Glass House’s more than 13,000 annual visitors. Continue reading →

Italy has not figured in our climate change solutions coverage, until now. Our thanks to Stephen Wallis and the New York Times for this:

A Growth Spurt in Green Architecture

Buildings made shaggy with vegetation or fragrant with wood are no longer novelties.

In the lineup of climate villains, architecture towers above many. The building and construction industries account for some 37 percent of worldwide carbon dioxide emissions, according to the United Nations Environment Program. Three of the most commonly used building materials — concrete, steel and aluminum — generate nearly a quarter of all carbon output. Continue reading →

Villa Triunfo, Old Farm & New School

/ Organikos / Leave a comment

We have shared a few posts in these pages mentioning Villa Triunfo, but now we have designed a new label for it. So, time to celebrate that. What is most important to us about the farm is that it is one of the oldest continuously operating coffee farms in Costa Rica, since its first plantings in the late 1800s.

That, and the fact that today it is also one of the more innovative in terms of pioneering hybrids that help the coffee stay fit in the context of climate change and the various challenges (such as the uniquely problematic mold that is called rust). It is the end of harvest season, when coffees in the West Valley are being processed. The red honey process used for this coffee allows all the sugars from the juicy fruit to absorb into the beans. We look forward to cupping it soon.

We missed Bloomberg’s story about Canvus back in November, but happy to share it now:

Retired Wind Turbine Blades Live on as Park Benches and Picnic Tables

To keep turbine blades from piling up in landfills, startups like Canvus are turning them into new products — and free marketing for wind power.

 

At first glance, the benches outside the Great Lakes Science Center in downtown Cleveland seem unremarkable. But a closer inspection shows that their droplet-shaped shells aren’t made from wood or metal. A scan of the attached QR codes reveals even more: These benches used to be wind turbine blades…

 

A big thanks to Yale Climate Connections for bringing Canvus to our attention today:

Nature, Peer-Reviewed Science Since 1869

/ Organikos / Leave a comment

The scientific journal Nature shows up in exactly one search result among thousands of posts here. And that one, because photos have such a wide audience. We have not linked to their articles because, since 1869, they are written by and oriented to highly credentialed scientists. A look at ten influential articles makes the point. And we can only respect what they do, even if we wish more of us could digest more of the science. Now that they offer some articles in audio version, this may make the science more accessible to those who hear better than they read. Judge for yourself, if you want to pay to play. The audio version of the article below (available on YouTube above) is free, but unless you have a subscription the written version is available for a small charge:

A new kind of solar cell is coming: is it the future of green energy?

Firms commercializing perovskite–silicon ‘tandem’ photovoltaics say that the panels will be more efficient and could lead to cheaper electricity.

On the outskirts of Brandenburg an der Havel, Germany, nestled among car dealerships and hardware shops, sits a two-storey factory stuffed with solar-power secrets. It’s here where UK firm Oxford PV is producing commercial solar cells using perovskites: cheap, abundant photovoltaic (PV) materials that some have hailed as the future of green energy. Surrounded by unkempt grass and a weed-strewn car park, the factory is a modest cradle for such a potentially transformative technology, but the firm’s chief technology officer Chris Case is clearly in love with the place. “This is the culmination of my dreams,” he says.

Pricing Flights Realistically

If airlines can quantify what it would cost to become carbon neutral within a relevant timeframe, it implies that we know by how much they are currently fudging their investment model. If it is going to require an investment of X number of dollars over Y number of years to achieve carbon neutrality then they should invest, and price their flights accordingly. Then we will all know the real cost of flying, including the environmental cost. Thanks to Umair Irfan (long time since we last saw his work) and to Vox for this:

Airlines say they’ve found a route to climate-friendly flying

Cleaner, faster, cheaper — the aviation industry’s plan to decarbonize air travel, explained.

If you’ve caught an ad for an airline lately on TV, a podcast, or the entertainment display on your flight, you’ve probably heard the company brag about what it wants to do about climate change.

Major airlines like American, Delta, Southwest, and United have all set targets of achieving net-zero greenhouse gas emissions by 2050. They’re using a suite of tactics including buying more fuel-efficient aircraft, electrifying their ground vehicles, and increasing the efficiency of their operations. They’re also testing the winds on battery- and hydrogen-powered planes, as well as some radically different aircraft designs. Continue reading →

Fungi & Fireproofing

/ Organikos / Leave a comment

Mycologist Zach Hedstrom sprays a spore-infused liquid to inoculate debris from forest thinning.

Inside Boulder Mushroom’s laboratory, a refrigerator houses an array of agar plates containing diverse mycelium cultures.

We have paid attention to mycological wonders for long enough that surprises are rare; but they happen. Stephen Robert Miller’s reporting, with photography by Jimena Peck were published in the Washington Post and came to our attention by way of the Food & Environment Reporting Network, which is where you can read the entire article:

How mushrooms can prevent megafires

Thinning forests to prevent fires produces a lot of sticks and other debris, which also pose a fire risk. In Colorado and elsewhere, scientists are using fungi to turn those trimmings into soil.

Overgrown stands of lodgepole pine are a risk for megafires. Thinning the stands simulates the effects of a natural fire but also generates a large amount of biomass, called “slash,” which can also fuel forest fires.

If you’ve gone walking in the woods out West lately, you might have encountered a pile of sticks. Or perhaps hundreds of them, heaped as high as your head and strewn about the forest like Viking funeral pyres awaiting a flame.

These slash piles are an increasingly common sight in the American West, as land managers work to thin out unnaturally dense sections of forests — the result of a commitment to fire suppression that has inadvertently increased the risk of devastating megafires. Continue reading →

If You Are In The Market For A New Puffer Jacket

The first and last time some of us heard the word bullrush was with regard to baby Moses. That may change. Thanks to Patrick Greenfield at the Guardian for bringing this company and its innovative product to our attention:

Goosedown out, bulrush in: the plant refashioning puffer jackets

By 2026, a rewetted peatland site in Greater Manchester will be harvesting bulrushes in a trial that aims to boost UK biodiversity, cut carbon emissions and provide eco-friendly stuffing for clothes

The humble bulrush does not look like the next big thing in fashion. Growing in marshes and peatland, its brown sausage-shaped heads and fluffy seeds are a common sight across the UK. Yet a project near Salford in north-west England is aiming to help transform the plant into an environmentally friendly alternative to the goosedown and synthetic fibres that line jackets, boosting the climate and the productivity of rewetted peatland in the process.

Replanting With Edibles

Your first taste of a ripe pawpaw, left, or American persimmon, right, may convince you to plant the trees, which can serve as the centerpiece of a permaculture food forest. J.B. Douglas

It is a relief, always, to read a Margaret Roach article when given the choice between her advice and any given news of the world:

Or just start by planting a few pawpaw or persimmon trees. Chances are, you’ll want more.

A long view of a food forest, with fruit trees growing in beds of companion plants.

At a permaculture site planted by Michael Judd, an edible landscape designer, each fruit tree is underplanted with beneficial companion plants, so “you’re not leaving your poor little fruit tree in a sea of grass,” he said. Michael Judd

Your first taste of a ripe pawpaw or persimmon can leave you hungry for more. That’s why Michael Judd is confident that he can persuade you to make room for several of these trees in your front yard — or even to surrender your lawn altogether.

Turning your yard into a meadow or blanketing it in an expanse of alternative ground covers aren’t the only ecologically viable options for replacing conventional grass. Continue reading →

Since 11+ years ago many valuable environmental opinions by George Monbiot have been linked to in our pages; today a celebration of a neighboring country’s efforts:

When it comes to rich countries taking the environment seriously, I say: vive la France

Emmanuel Macron’s government is at least doing the bare minimum to avert the planetary crisis – and putting the UK to shame

While we remain transfixed by a handful of needy egotists in Westminster and the crises they manufacture, across the Channel a revolution is happening. It’s a quiet, sober, thoughtful revolution, but a revolution nonetheless. France is seeking to turn itself into an ecological civilisation. Continue reading →

Food Waste Best Practice, South Korea Edition

One of the most covered topics in our pages during the decade since we started paying attention to it, still going strong for all the wrong reasons; so, our thanks to the New York Times for assigning John Yoon (reporting, writing) and Chang W. Lee (for photographs and video) to go to South Korea:

When wasted food rots in landfills, it pollutes soil and water — and warms the planet. Here’s how one country keeps that from happening.

Around the world, most of the 1.4 billion tons of food thrown away each year goes to landfills. As it rots, it pollutes water and soil and releases huge amounts of methane, one of the most potent greenhouse gases. Continue reading →

Taking Better Care With Help From Kate Raworth

What? We never posted on this book or its economist author before? We correct that now with Hettie O’Brien’s article in the Guardian :

The planet’s economist: has Kate Raworth found a model for sustainable living?

Her hit book Doughnut Economics laid out a path to a greener, more equal society. But can she turn her ideas into meaningful change?

Consider the electric car. Sleek and nearly silent, it is a good example of how far the world has progressed in fighting the climate crisis. Its carbon footprint is around three times smaller than its petrol equivalent, and unlike a regular car, it emits none of the greenhouse gases that warm the planet or noxious fumes that pollute the air. That’s the good news. Then consider that the battery of an electric car uses 8kg of lithium, likely extracted from briny pools on South America’s salt flats, a process that has been blamed for shrinking pasturelands and causing desertification.

The 14kg of cobalt that prevent the car’s battery from overheating have probably come from the Democratic Republic of the Congo, where cobalt mines have contaminated water supplies and soil. As the demand for electric vehicles grows, the mining and refining of their components will intensify, further damaging natural ecosystems. By 2040, according to the International Energy Agency, the global demand for lithium will have increased more than fortyfold. Continue reading →

About 80 percent of new-car sales in Norway were electric last year, putting the country at the vanguard of the shift to emissions-free vehicles. David B. Torch for The New York Times

A major fossil fuel producing country has figured out how to transition away from combustion engines:

About 80 percent of new cars sold in Norway are battery-powered. As a result, the air is cleaner, the streets are quieter and the grid hasn’t collapsed. But problems with unreliable chargers persist.

Thanks to the team at Yale Climate Connections:

When do many people decide to go solar? When they’re referred by a friend or neighbor.

They’re more likely to listen to people they trust.

Rooftop solar panels can save people money on their electricity bills. And those savings can mean a lot — especially for people with low incomes, who might have to choose between paying for utilities or buying food or medicine…

 

Bio-Based Gains

We have been watching and waiting for this range of products to have their day, and Jim Robbins delivers an up to date account that gives hope:

From Lab to Market: Bio-Based Products Are Gaining Momentum

A 3D-printed house made from sawdust and other timber industry waste by the University of Maine’s Advanced Structures and Composites Center. UNIVERSITY OF MAINE

Propelled by government investment and shareholder demand, manufacturers are pushing to get bio-based products into the marketplace. These new materials — made from plants, fungi, and microbes — aim to replace those that contain toxins and are difficult to recycle or reuse.

In the 1930s, the DuPont company created the world’s first nylon, a synthetic polymer made from petroleum. The product first appeared in bristles for toothbrushes, but eventually it would be used for a broad range of products, from stockings to blouses, carpets, food packaging, and even dental floss.

Nylon is still widely used, but, like other plastics, it has environmental downsides: it is made from a nonrenewable resource; its production generates nitrous oxide, a potent greenhouse gas; it doesn’t biodegrade; and it sheds microfibers that end up in food, water, plants, animals, and even the clouds.

Now, however, a San Diego-based company called Genomatica is offering an alternative: a so-called plant-based nylon made through biosynthesis, in which a genetically engineered microorganism ferments plant sugars to create a chemical intermediate that can be turned into nylon-6 polymer chips, and then textiles. The company has partnered with Lululemon, Unilever, and others to manufacture this and other bio-based products that safely decompose. Continue reading →

Great EV Expectations

I had no reason to bet against Tesla until now, but I did wonder whether it was good for anyone (other than its shareholders) for that one company to dominate its market over the longer term. Now, happily, it looks like the market will do what we need it to do, which is get robust:

For U.S. Companies, the Race for the New EV Battery Is On

Spurred by federal mandates and incentives, U.S. manufacturers are pushing forward with developing new battery technologies for electric vehicles. The holy grail is a battery that is safer, costs less, provides longer driving range, and doesn’t use imported “conflict” minerals.
