The designs for Notre Dame's new roof are eco-friendly and cool AF.

On April 15th, France lost part of one of its most iconic buildings — Notre Dame Cathedral. However, fundraising efforts for the rebuild began quickly, and now there are several design firms competing for the job.

France also opened the bidding up to international designers, and that really fanned the flame of the competition. Within the past month, grand design plans have been pouring in, and some of the most interesting ones go beyond historical restoration to directly address one of the world's greatest challenges — climate change.

Hey, the Paris Agreement doesn't have to be the only innovative green initiative in France, right?

One particularly cool, eco-friendly design is from French design firm Vincent Callebaut. Their "Palingenesis" design is not only a beautiful glass structure, it would also be a light-absorbing greenhouse that's meant to provide the Cathedral with 100% clean energy.

“The new wooden frame is covered with a three-dimensional crystal glass dress subdivided into faceted diamond-shaped elements," the firm noted in a press release. "These crystals consist of an organic, active layer made of carbon, hydrogen, nitrogen and oxygen, which absorbs light and transforms it into power. This energy, stored in hydrogen fuel cells, will be directly redistributed throughout the cathedral.”

The firm also plans to build an urban garden inside the structure that would be fertilized by aquaponics (natural fish-made fertilizer). The sizable-sounding crops would mostly go to underserved communities in Paris, making the entire design beautiful, environmentally sustainable, and socially responsible.

But I'll just shut up and let you look at some more pictures of the awesome thing.

Vincent Callebaut isn't alone in their idea to create a green space on top of Notre Dame. Another French firm also wants to create a greenhouse, but one that's only accessible to birds and insects.

“[The] Notre Dame tragedy should serve the cause of the environment, the greatest struggle of humanness, by being a new world symbol for the present and future generations," studio director Abel Guillaume told Fast Company. people would still be able to enjoy them and the space, but they'll have to do it from behind glass.

NOTRE DAME - Proposal Une proposition de @summumarchi , donner l’accès aux combles de notre dame pour en faire un parc commémoratif, aux couleurs pourpres en mémoire de l’incendie, tout en profitant de cet énorme élan de générosité à travers les dons pour en faire un sanctuaire pour les animaux et insectes toujours plus menacés dans les villes. Que cette reconstruction serve l’environnement, et démontre au reste du monde le savoir faire de nos compagnons français à travers une architecture magnifiée, technique, intemporelle, au plus haut niveau de ce que l’on sait faire.

Studio Nab also wants to provide a refuge for insects, but a specific kind of insect that's already native to Notre Dame — bees. 180,000 bees have resided on the Cathedral since 2013, and thankfully survived the fire. Studio Nab's greenhouse structure would provide them with a safe space that's open to the public so people can learn about the importance of bees and how to properly maintain urban agriculture.

One idea that's somewhat speculative is Studio Drift's plan to use recycled plastic found in the ocean to create a new roof for the cathedral. They claim redoing the roof in wood would require cutting down lots of trees whereas upcycling plastic waste is sustainable, and whatever they save in cost they plan to put back into the efforts to clean up the oceans.

It sounds nice in theory, but since the other firms above are using glass and adding more sustainable elements, this idea trails a bit behind theirs.

That said, it's great to see so many designers attempting to incorporate the planet's future into a design for a relic from the past. It'll be exciting to see which one of these ambitious projects wins out in the end.

Your empty beauty products can do a lot more than sit in a landfill.

You know that feeling when you step into a hot shower after a long, hard day?

Between the blast of steam, the sensation of suds on your scalp, and the incredible acoustics that nearly convince you to drop everything and audition for The Voice, it’s undoubtedly one of the best routines out there.

The thing about routines is — you don’t have to think that much about them. (I mean, when’s the last time you really CONSIDERED your toothbrush?) But what if we zoomed out for a second and gave some thought to the everyday items we reach for that keep us looking and feeling our best?

Like, did you know that something as basic as your shampoo bottle could achieve greatness? No joke.

And no, we’re not just talking about its impact on your luscious locks.  

We’re talking about the bottles themselves.

After the last lather, your colorful bottle has the potential to get repurposed into something awesome. But many bottles never get the chance and, instead, end up in the landfill.

The fact is, nearly 50% of Americans don’t recycle their used beauty products. That’s a huge burden on our environment, and it has to stop.

Fortunately, some major beauty product companies are taking significant steps towards change. For example, Garnier is implementing some seriously impressive sustainability practices to help provide a comprehensive solution to beauty packaging waste.

So, instead of ending up in a landfill, shampoo bottles like yours can take on a whole other life.

It all starts at the factory.

You see, back when your bottle was just a glimmer in a manufacturer’s eye, some brands were thinking of the big picture and adopted sustainable practices at the ground level.

Garnier, for one, has reduced emissions at their plants and distribution centers, decreased the amount of packaging, and is using recycled materials in their products. Many of their hair care offerings incorporate PET plastic into their packaging, one of the more environmentally friendly plastics like the kind used in soda bottles.

Additionally, some of Garnier’s packaging also uses 50% post-consumer recycled material (PCR) — which means it’s already served one purpose and has now been remade into a different product.

So, before it found its way into your shower stall, your shampoo bottle could’ve already lived another life. Just think — it may have been part of the tennis ball used to win Roger Federer his eighth straight men’s singles title at Wimbledon.

And its journey doesn’t have to end just yet — as long as you know where to send it.

A lot of people don’t know how to recycle their shampoo bottles. Many of these bottles are actually unable to be grouped with regular recycling, so more often than not, they just get thrown in the trash.

That’s where Garnier is stepping in. In an effort to educate consumers on better recycling practices, they’ve partnered with TerraCycle — a company focused on recycling commonly non-recyclable materials.

They’re calling it their Personal Care and Beauty Recycling Program, which they hope will provide an easy solution for consumers to make a real impact.

Here’s how it works:

When it’s time to throw out your personal care products, spare them from the landfill and send them to TerraCycle instead. It’s entirely free and totally possible to do from your own home. It’s a small effort, but trust us, these bottles can add up to make a big difference.

Once you've collected 10 pounds or more, mail them in, and Garnier will donate two cents for every personal care product to the charity of your choice. There’s never been a better reason to shower twice a day. (Unless maybe if you’re a long-distance runner in Death Valley… Then, you do you.)

However, if you’re not literally planting a tree and watching it grow or picking up trash on your street — both awesome things you should totally do, by the way — it can be hard to see the positive impact your actions have on the environment.

So, when you mail in a box full of your used bottles, it might leave you wondering what exactly they will be used for.

Rest easy: Those bottles could end up doing amazing things for a community in need.

After TerraCycle collects your bottles and many others like yours, they repurpose them into something entirely new and awesome, like park benches. That’s right, someone might be enjoying a lovely afternoon in the park sitting on your favorite hair sudser.  

And that’s just the beginning.

Thanks to Garnier, some of these bottles also go towards the creation of awesome eco-friendly projects, like this community garden in Harlem, which is made up of 1,500 pounds of recycled personal care waste. Just imagine, your bottle might be living out its destiny helping to grow fresh and sustainable nutrition for an entire community.

Some recycled bottles even get turned into recycling bins, inspiring others to follow your lead in saving the planet.

That’s a lot of impact for something that regularly goes overlooked. But your little bottle can’t do all that on its own.

The commitment to living sustainably, limiting landfill waste, and ultimately saving the planet is very much a group effort.

Change happens on all levels — from the factory floor to your shower. And while companies like Garnier and TerraCycle are making a major effort, it’s up to us as individuals to keep the green trend going and make sure beauty products stay out of landfills.

So far, the group effort seems to be working —more than 10 million bottles have already been diverted.

That’s a huge impact, but it’s only the beginning. More and more companies are prioritizing sustainability and more consumers are adopting these impactful recycling practices.

When it comes to the environment, we can only afford to move forward.

Turns out this amazing planet and a single shampoo bottle have something in common — they are both just too precious to waste.

Every decision impacts the Earth, especially when it comes to personal products.

Did you know that every time you buy something, you can make a big difference to the planet?

It's true. Just ask Brad Kahn.

He is the director of communications at the Forest Stewardship Council (FSC), a nonprofit that works tirelessly to promote responsible management of the world's forests, so he knows quite a bit about protecting the Earth. And part of it, he says, is making good choices in the store.

Any time you make a purchase, he says, "you're actually making a decision about the environment."

"I think people don't really realize how pervasive forest products are. Virtually every business on Earth uses forest products in one way or another," he continues.

The good news is, it isn't hard to make smart choices for the environment.

It just starts by choosing products from companies that are working to do good.

L'Oréal, for instance, has aglobal program dedicated to integrating sustainability into all areas of their business.

For example, all of L'Oréal's U.S. facilities incorporate 100% renewable electricity — and they will be carbon neutral by 2019.

And that's not all.

Danielle Azoulay, head of corporate social responsibility and sustainability for L'Oréal USA, says that the company's size is part of what makes their environmental efforts so important.

"At L'Oréal, we take a holistic approach to sustainability. From carbon emissions reductions to water stewardship in our factories, we're working to improve our environmental footprint across the company, every day," she writes.

"We've been focusing on light-weighting and integrating recycled materials into our packaging," she continues, "and [we] continue to encourage our consumers to recycle products once they're done using them."

"As the largest beauty company in the U.S. and the world, when we apply these changes across our brand portfolio, we have the opportunity to make an enormous positive impact on our communities, translating to big wins for the planet," she explains.

It also helps that organizations like the FSC help shoppers easily identify these sustainably packaged products from brands — like Garnier — that are committed to reducing their harmful impact on the planet. All you have to do is glance at a product's packaging, and if you see an FSC logo — which usually shows up on the back — you'll know it's certified as forest-friendly.

When it comes to the beauty industry in particular, doing the right thing is important.

Industry organizations and media point to data briefings from market researcher Euromonitor that indicate the global cosmetics industry produces more than 120 billion units of packaging every year.

That's why, for their boxes of hair color and skin-care products, Garnier, a brand in L'Oréal's portfolio,uses all FSC-certified paper. It's one of many strategies — along with similar thought given to plastics, glass, and energy use — that the brand uses to reach their sustainability goals.

That means, for example, that someone looking for a bright new look could buy shampoo that comes in recycled plastic and hair color in sustainably-sourced cardboard.

You're also keeping those bottles out of landfills. In 2014, Americans discarded about 33.6 million tons of plastic — a number that we can all impact by making smart choices, backing the brands that are committed to doing better. For example, all of Garnier's shampoo and conditioner bottles are made of recyclable PET plastic.

Looking out for packaging with sustainable materials is a simple shift that doesn't force you to compromise your beauty and personal care needs.

You still get to stick with the routine that's best for your hair and skin — and feel even better by making smarter choices for the planet, too.

To put it in perspective, Kahn says:

"There is no chance of life on Earth without healthy forest ecosystems. I don't think that's an exaggeration because forests provide much of the air we breathe, something like two-thirds of the water that we drink, the carbon storage to have a stable atmosphere. … We really rely on forests every day."

So when you've seen the FSC logo on your packaging, and you know your shampoo bottle is made from recycled plastics, feel free to sing your heart out with that shampoo bottle in the shower — as one of our planet's heroes, you've earned that joy.

What if cement could help save the planet? Thanks to this discovery, it might.

True
UCLA Optimists

Earlier this year, a Swiss startup began removing CO2 from the atmosphere using a large vacuum-like machine.

Their ultimate goal is to start reversing the damaging effects of climate change by reducing CO2 — a major component of atmospheric pollution — on a global scale.

While the machine's development is a huge step forward, one little problem remains — where does all that collected CO2 go?

Gaurav Sant, a professor of civil and environmental engineering at UCLA, has one solution: turn it into cement.

(And we're not just talking about any old cement.)

Sant has figured out how to make a stronger, more lightweight, more structurally sound cement out of — wait for it — CO2.

Believe it or not, the regular construction of cement is responsible for 9% of the world's CO2 emissions. And it is widely accepted that CO2 emissions play a huge role in global warming and, by effect, climate change.

Sant, along with his team at UCLA, decided to try to turn two negatives into a positive. They found a way to integrate CO2 into the production of cement, thereby keeping it out of the atmosphere and upcycling it into something useful and even profitable.  

It all started from tiny cement cylinders created by Sant's 3D printer.

Well, that and a pretty important discovery of how CO2 can help accelerate the cement-making process.

In simplest terms, Sant's team discovered that the CO2 in flue gas streams from coal and natural gas power plants accelerates the mineral-making processes that can be used to create cementing agents. They decided to use CO2 to produce a new type of concrete that they've named CO2NCRETETM.

Curious how they did that? Here's the breakdown.

When a mineral called portlandite absorbs CO2, it turns into limestone, which is a cementing agent. While this process normally takes years to happen naturally, Sant's team figured out how to make it happen quickly — 450 pounds of CO2 into several tons of CO2NCRETETM quickly — and efficiently using their 3D printer.

Unlike traditional cement-making on a construction site, 3D technologies allow them to create basic construction pieces out of their new CO2-based concrete that fit together perfectly.

This means they can make cement pieces that are stronger, more lightweight, and more structurally sound.

"As a child that played with Legos, I have long recognized that the idea of constructing buildings and infrastructure like a large Lego set is (a) fast, (b) intuitive, and, (c) offers improved quality control since 'factory made' pieces are simply assembled on site," Sant explains in an email.  

What sort of impact could this have on reducing global CO2 emissions? Turns out, a pretty big one.

According to Sant and his team, if CO2NCRETETM were to be mass-produced globally, it could reduce CO2 emissions from traditionally made cement by 50%. And since those emissions currently make up 9% of all CO2 emissions on the planet, that's no small amount.

What's more, since there's been little change made in the construction industry over the last two centuries, it's primed for an efficiency makeover.

"CO2NCRETETM has the potential to serve as an example of how CO2 emissions — even those associated with dilute CO2 streams — can be repurposed to create value and minimize environmental impact," writes Sant.

[rebelmouse-image 19475647 dam="1" original_size="1280x854" caption="Photo by Robert Jones/Pixabay." expand=1]Photo by Robert Jones/Pixabay.

And it's not like this goal is a faraway dream. They've made incredible progress on this new cement and are starting to shop it around.

They've figured out how to streamline the cement-making process so it takes much less time and energy than it did initially. They've also done an analysis of the construction market and see huge potential for such a sustainable product.

"This is especially significant as jurisdictions, globally, including states and nations, seek to limit CO2 emissions and impose CO2 penalties on industrial processes," writes Sant.

And in terms of progress with CO2 capture, Sant's work could offer an economically viable alternative to storing the CO2 underground, which can get pretty expensive.

If the world recognizes the economic value of upcycled cement along with the environmental impact, this discovery could revolutionize the future of construction.

Engineering solutions like this can offer a way to mitigate climate change and be profitable at the same time. Now it's just about keeping an open mind and seeing the enormous potential in a small, concrete cylinder.

As for Sant and his associates, they're just thrilled to be on the precipice of real, necessary change.

"As humans, we all want to make positive impact," says Sant. "To be a part of the solution is a very empowering accomplishment that we wish to socialize."
