Cheese Byproduct Transforms E-Waste into Gold

Cheese Byproduct Transforms E-Waste into Gold: ETH Zurich’s Groundbreaking Innovation

BNN Correspondents, BNNBreaking.com, February 29, 2024

ETH Zurich researchers develop a novel method to extract gold from e-waste using cheesemaking byproducts, paving the way for sustainable technology.

In an astonishing leap towards sustainable technology, researchers led by Professor Raffaele Mezzenga at ETH Zurich have developed a novel method to extract gold from electronic waste using a byproduct of the cheesemaking process. This innovative approach not only promises to revolutionize gold recovery but also offers a cost-effective and environmentally friendly solution to a growing global challenge.

From Dairy to Gold: The Science Behind the Innovation

The team, including senior scientist Mohammad Peydayesh, has ingeniously utilized denatured whey proteins to create a sponge capable of extracting gold from the acid-dissolved metal parts of old computer motherboards. The method hinges on the proteins’ ability to form nanofibrils that adhere to gold ions more efficiently than to other metals. Following the absorption process, the gold ions are reduced to flakes and then melted down to form a nugget. Remarkably, the researchers obtained a 450-milligram nugget of 91 percent pure gold from just 20 motherboards, demonstrating the method’s efficiency and potential for scalability.

These Are the Climate Grannies. They’ll Do Whatever It Takes to Protect Their Grand children

Jessica Kutz, InsideClimateNews.org, February 3, 2024

They have the generational wisdom, environmental activism experience, free time—and they’re not afraid of getting arrested.

Hazel Chandler was at home taking care of her son when she began flipping through a document that detailed how burning fossil fuels would soon jeopardize the planet.

She can’t quite remember who gave her the report — this was in 1969 — but the moment stands out to her vividly: After reading a list of extreme climate events that would materialize in the coming decades, she looked down at the baby she was nursing, filled with dread.

“‘Oh my God, I’ve got to do something,’” she remembered thinking.

It was one of several such moments throughout Chandler’s life that propelled her into activist spaces — against the Vietnam War, for civil rights and women’s rights, and in support of other environmental causes.

She participated in letter-writing campaigns and helped gather others to write to legislators about vital pieces of environmental legislation including the Clean Air Act and the Clean Water Act, passed in 1970 and 1972, respectively. At the child care center she worked at, she helped plan celebrations around the first Earth Day in 1970.

Now at 78, after working in child care and health care for most of her life, she’s more engaged than ever. In 2015, she began volunteering with Elder Climate Action, which focuses on activating older people to fight for the environment. She then took a job as a consultant for the Union for Concerned Scientists, a nonprofit science advocacy organization.

How our drinking water could come from thin air

Martine Paris, BBC.com, February 5, 2024

From solar panels that produce water to ‘self-filling’ coffee machines and water coolers, technology companies are putting a new spin on a centuries-old technique.

In the dry, desert air of Las Vegas, it seems strange to be talking about a plentiful source of water all around us.

Southern Nevada is in the grip of one of the worst droughts it has experienced in recorded history, leading to water shortages and restrictions on use. So, in water-stressed areas such as this, the prospect of wringing water from thin air is an appealing prospect. And it is exactly what Cody Friesen is trying to do.

Friesen, an associate professor of materials science at Arizona State University, has developed a solar-powered hydropanel that can absorb water vapour at high volumes when exposed to sunlight.

It is a modern-day twist on an approach been used for centuries to pull water from the atmosphere, such as using trees or nets to “catch” fog in Peru, a practice that dates back to the 1500s and is still being used today.

Amid the flashy transparent televisions and electric vehicles at the Consumer Electronics Show (CES) in Las Vegas in January, there were a few start-ups claiming to have new ways of exploiting this ancient, and often overlooked source of clean drinking water. And with the help of artificial intelligence, they’re finding ways of pulling even more water out of the air.

Friesen founded his own company Zero Mass Water in 2014 following his research on solar-powered hydropanels. Today the company is called Source Global, operates in more than 50 countries and has a private valuation of more than $1bn (£800m).

AI could accelerate progress toward the world’s climate goals. Here’s how

Kate Brandt and Rich Lesser, Fortune.com, December 18, 2023

The world must dramatically reduce greenhouse gas emissions by 2030 to meet Paris Agreement goals. Yet based on current trajectories, emissions are set to rise by 10% over the next eight years. This will only accelerate widespread droughts, flooding, extreme heat, and other devastating impacts across the globe.

Against this challenging backdrop, it is clear that acceleration is needed across all fronts of climate action. One of those opportunities lies in artificial intelligence (AI). Research shows that by scaling currently proven applications and technology, AI could mitigate 5 to 10% of global greenhouse gas emissions by 2030–the equivalent of the total annual emissions of the European Union. For the first time, AI was highlighted at COP28 as one of the key potential solutions to tackle climate change, with the United Nations Framework Convention on Climate Change (UNFCCC) announcing the AI Innovation Grand Challenge at the conference to identify and support the development of AI-powered solutions for climate action in developing countries.

Reversing the emissions trajectory will take everyone involved–government officials, business leaders, and technologists–all rowing the boat in the same direction. Policymakers have a central role to play, with three critical priority areas that will allow AI to contribute to its full potential.

First, policies must enable AI innovation and adoption for climate-positive applications. Data sharing frameworks, investment in research, affordable technology access, and education initiatives are needed to drive development and deployment. Government has a key role to play as an end-user. In the absence of clear community, national, or sector-specific objectives for climate action, AI-driven innovation could go off in disjointed directions. Resource allocation would be inefficient. Establishing priority innovation domains where AI could most immediately and effectively advance climate action–such as leveraging AI for flood-resilient farming, climate change adaptation, and accelerating the energy transition–can unlock resources and focus minds.

Nine breakthroughs for climate and nature in 2023 you may have missed

By Future Planet team, BBC.com, December 14, 2023

In a tumultuous year, the positive milestones for the climate and nature might well have gone under your radar. Future Planet rounds up nine quiet wins of the year, plus one much louder one.

Record-setting spending on clean energy in the US. A clean energy milestone in the world’s power sector. A surge in lawsuits against polluters. A treaty for the oceans 40 years in the making.

This year has seen some remarkable steps forward in tackling the nature and climate crises.

But in a year like 2023, it’s natural our attention has been drawn to the environmental disasters that have dominated the headlines. Add to that our “negativity bias”, which affects the information we are most drawn to, and you can see why any positive developments over the past 12 months feel very quiet by comparison.

Some breakthroughs also don’t get shouted about because they are being led by grassroots communities or indigenous groups whose voices are often marginalised. And sometimes, as we’ll see, a climate win is quiet for a reason.

This is why we’ve gathered some of the “quiet wins” of 2023 for the climate and nature, to make sure these breakthroughs don’t escape our attention.

Here are nine positive developments worth your notice, plus one louder change.

1. A huge boost for clean energy

In the US, the green energy transition has received a massive boost from the Inflation Reduction Act. Passed in 2022, the bill includes $369bn (£294bn) for action to reduce greenhouse gas emissions, support clean energy and encourage electrification. It was quickly welcomed as the largest climate investment in US history, although it isn’t at all obvious from the legislation’s name – perhaps making it the definition of a “quiet” climate win.

The surprising connection between eco-anxiety and loneliness

James Arnott and Shannon Stirone, YaleClimateConnections.org, December 19, 2023

Recent research shows that the unfolding crises in climate change and social isolation may actually be connected.

The climate crisis isn’t just altering our physical environments. It could even be transforming our minds and how we connect to each other.

Many people are experiencing escalating anxiety levels about the potential for extreme weather events and the safety of their homes, property, and livelihoods. Still more are numbed by general ennui about how the planet and our existence are being fundamentally altered. And evidence is growing that in addition to altering our environment, the climate crisis could be transforming our minds.

“Climate change is inside us,” said Clayton Aldern, a neuroscientist and author of the forthcoming “The Weight of Nature: How a Changing Climate Changes Our Brains,” one of a number of recent books and studies that delve into how climate change affects our brains, our mental health, and the connections we make with each other.

A connection to loneliness

Researchers are finding that the climate crisis is unfolding alongside crises in mental health and social isolation — and suggest some striking ways these issues may be intertwined. The collective stress, fears, and isolation caused by climate-related events, dubbed eco-anxiety, could be making people more lonely, in turn hurting health, relationships, and collective ability to act.

Action And Activism: Gen Z Influence On Holiday Shopping

Action And Activism: Gen Z Influence On Holiday Shopping, Zoryana Zagorodnya, Forbes.com, December 1, 2023

It’s the “most wonderful time of the year” again, when our thoughts turn to jingly bells, Christmas carols, and the mad dash to find that perfect gift for loved ones. According to a recent NRF survey, we can expect to see a 4% increase in holiday shopping sales this year with e-commerce expected to surpass brick-and-mortar. But that’s not the only surprise.

While studying Gen Z behavior, it was discovered that experiences linked to action and activism hold the most significance. Gen Z are known for their proactive nature, meticulous attention, efficient use of time, and mindful approach to consumption.

While not considered “traditional” shoppers, Gen Z is still expected to have a major impact on holiday sales this year. According to recent PwC research, they will spend 15% more than 2022 which is the widest percentage increase of any age group. Let’s take a closer look at what this means.

How Gen Z’s shopping behavior is different from the other generations

Gen Z consumers crave personalized experiences more than any other age group. According to Statista research, 52% percent of Gen Z’s are likely to buy a personalized gift versus 36% of the general public.

That is one reason why e-commerce, and increasingly social commerce, is so influential. A Gen Z consumer is more likely to order gifts directly through social media marketplaces.

Right now, TikTok recommendations are full of trending items for Christmas 2023 that you didn’t know you needed, probably don’t need, but will want to buy anyway. Novelty gifts, decorations, outfits for New Year’s Eve, and of course make-up trends like which red lipstick to choose to look just stunning are a few examples.

Influence of sustainability

A recent study conducted by IBM revealed that a significant 73% of consumers now consider sustainability a major factor when making their holiday purchases. 29% of responders take carbon emissions seriously, while 38% will try to reduce the usage of single-use plastics during this holiday season.

Does Working From Home Save Companies Money?

Baruch Silvermann, Business.com, November 6, 2023

When the pandemic hit, many Americans with jobs that didn’t require face-to-face interaction were forced to work from home. This paradigm shift in how companies and employees managed operations created new norms and expectations. Many employees enjoyed ― and continue to embrace ― the freedom and flexibility of remote work plans.

Business owners have other factors to consider. If allowing your team to work from home can help you reduce operational costs or give your company other competitive advantages, you have a win-win situation. Here’s what business owners should know when evaluating the benefits of allowing remote work.

How working from home can save companies money

Along with remote work’s benefits for workers, business owners may find that remote work saves their companies money. For example, Sun Microsystems identified telecommuting-prompted savings of $68 million yearly in real estate costs while Dow Chemical and Nortel saved over 30 percent on non-real estate costs.

According to Global Workplace Analytics, nearly 60 percent of employers identify cost savings as a significant telecommuting benefit. It estimates that for all remote-work-compatible jobs, if everyone who wanted to work remotely did so just half of the time, the total money saved would be over $700 billion annually. This averages out to more than $11,000 per employee per year.

Here are some concrete ways remote work saves businesses money:

Remote work saves on rent and utilities: If most of your team works from home, your office space needs won’t be as significant, saving money on rent and utilities.
Remote work saves on relocation costs: Many companies pay for key employees to relocate. However, this isn’t necessary if the employee can remain in the same place and work remotely.
