"We're taking CO2 out of the system" says carbon-capturing concrete maker Carbicrete

Montreal company Carbicrete has developed a method for sequestering carbon in concrete, claiming its product captures more carbon than it emits.

The technology cuts out the need for calcium-based cement, a key ingredient in traditional concrete that is responsible for around eight per cent of all global CO2 emissions.

"It's negative emissions," Carbicrete CEO Chris Stern told Dezeen. "We're taking CO2 out of the system every time we make a block."

Concrete locks carbon away "forever"

The company is one of many that is racing to find low-carbon or carbon-free alternatives to traditional concrete but is one of the only ones claiming to have achieved negative carbon.

Instead of cement, Carbicrete's system combines waste slag from the steel industry plus carbon captured from industrial plants that would otherwise have gone into the atmosphere.

"We're taking it from there and then injecting it into concrete and getting rid of it forever," Stern said.

More carbon is captured during the production process than is emitted during the manufacture of the concrete, making the resulting concrete carbon-negative according to Stern.

However, the process relies on emissions produced by other industries, so it is helping to reduce the amount of additional CO2 going into the atmosphere rather than actively removing it from the atmosphere.

But as CO2 captured from the sky via direct air capture (DAC) companies such as Climeworks becomes more affordable, concrete could start to play a part in lowering concentrations of atmospheric carbon.

"We'd love to get it from a direct air capture unit," Stern said. "We're not there yet just because the industry is not there yet but it's certainly well-positioned for us."

Technology could eliminate hundreds of megatons of emissions

Carbicrete, which was founded in 2016, licenses its technology to concrete manufacturers who can integrate it into their existing production processes for concrete masonry units (CMUs) and precast panels.

In collaboration with Quebec manufacturer Patio Drummond, the company is building up its production capabilities to 25,000 CMUs per day while the first building using material is set to be built in Canada at the start of next year.

Once scaled up, Stern believes the technology can help to reduce the 2.2 billion tonnes of carbon emissions that are generated by the cement industry every year.

"We can take care of megatonnes on a yearly basis, [capturing] anywhere between 100 and 300 [million tonnes of CO2]," Stern explained. "So it's definitely going to make a dent."

Process works without cement

Carbicrete's technology cuts out the need for cement, the binding agent that makes up around 12 per cent of traditional concrete but is responsible for half of the material's carbon footprint.

To make cement, calcium carbonate (usually in the form of limestone) is heated to around 1,480 degrees Celsius to extract calcium oxide.

This process releases carbon dioxide, which accounts for 40 per cent of limestone's mass, into the atmosphere. The energy-intensive process is usually powered by fossil fuels, creating additional emissions.

Carbicrete's method circumvents these emissions, cutting out approximately two kilograms of CO2 for every concrete masonry unit.

As a substitute, the company uses a waste byproduct from the steel-making process called slag, which contains calcium oxide.

In traditional concrete production, cement is cured with water, causing the calcium to react with the CO2 in the surrounding air and turning it back into strengthened calcium carbonate.

The company is currently scaling up its processes to produce 25,000 CMUs per day

But in Carbicrete's system, the calcium oxide is instead injected with CO2 captured from industrial sites. This curing process creates calcium carbonate, which helps to fortify the concrete.

"It's effectively doing the same job as hydration in a regular concrete product," Stern explained. "The chemical composition of a concrete block that we make is exactly the same as a regular concrete block but we take a different road to get there."

This curing process takes 24 hours and stores away three kilograms of CO2 per CMU by converting them into a stable mineral, alongside an additional kilogram of CO2 that is pulled from the surrounding air during the curing process.

"The only way CO2 will escape one of our concrete blocks is if somebody burns the block," Sten said. "And nobody does that on purpose."

The resulting carbonated concrete can have up to a 30 per cent higher compressive strength than conventional concrete, the company claims. And since its production process requires no heat, Stern says its energy consumption is "literally not comparable" to that of traditional cement.

System is dependent on steel slag supply

However, the scope of Carbicrete's potential is limited. Currently, its carbon curing process can only take place in the controlled environment of a factory, restricting its use to products such as CMUs and concrete panels that are cast in advance of being delivered to a construction site.

This precludes its use in liquid ready-mix concrete, which is cast and cured on-site to create a building's foundations and floors. To serve this market, Carbicrete is developing a new technology that won't be ready for another five to 10 years.

"It all comes down to how we can make a mobile, flexible curing system and have that on-site," Stern explained.

The technology can so far only be used on precast CMUs and panels rather than ready-mix concrete

Another problem is the supply of steel slag. Only around 250 million tonnes of the industrial byproduct are produced every year compared to four billion tons of cement.

"There's not enough steel slag to make enough concrete to serve the world's needs on a yearly basis," Stern said.

"It's possible to replace 10 to 20 per cent of the current concrete production," he added. "But concrete is the second most-consumed resource on the planet outside of water. So if we make a billion tonnes of concrete, that's a massive amount."

Potential of carbon-cured construction materials 

A number of other companies are exploring alternative methods to reduce the carbon footprint of concrete. Although these solutions are not carbon neutral, they are currently available at a much larger scale.

New Jersey-based Solidia uses carbon instead of water to cure a special cement that is low in lime, reducing CO2 emissions by up to 70 per cent.

Amazon's HQ2 in Arlington will be built using CarbonCure concrete

Meanwhile, Canadian start-up CarbonCure uses captured CO2 emissions to cure regular cement, reducing the amount of cement needed to create a batch of ready-mix concrete and cutting emissions by five per cent.

More than eight million cubic metres of concrete has already been made using the company's technology.

This equates to thousands of buildings, according to CarbonCure's senior director of sustainability Christie Gamble, as will also include "every cubic metre of concrete" in Amazon's new NBBJ-designed headquarters in Arlington, Virginia.

"Carboncure is on a mission to reduce 500 megatonnes of carbon emissions annually by the year 2030," Gamble told Dezeen. "To date, we've been able to reduce over 100,000 tonnes of CO2. We're proud of that reduction so far [but] we still have a long way to go."

CarbonCure injects CO2 into standard concrete mix from a pressurised tank

Elsewhere, UK company Carbon8 Systems has developed a modular technology that fits into a shipping container and can be installed at cement plants to capture their CO2 emissions.

These are then used to cure bypass dust – a powdery byproduct of cement production – creating a "carbon-negative aggregate" that sequesters cement industry emissions while also cutting out the emissions associated with mining and transporting traditional aggregate.

When taken together, UK Concrete estimates that these kinds of carbon capture, utilisation and storage (CCUS) technologies could deliver 61 per cent of the carbon savings the concrete and cement industry claims it needs to make to become net carbon negative by 2050.

"The answer is not that you use CarbonCure or this other sustainability solution," Gamble said. "The answer is: use both and incorporate all of these strategies."

Tips On Designing Creative Websites That Will Wow Your Clients

The global market keeps getting bigger and bigger, which should be good news for web designers – but there’s a catch.

The clients you can expect to serve are more sophisticated and want creative websites, not just the regular HTML and CSS.

You can’t deliver just anything and expect them to be happy. You’ll also have some serious competition to contend with. As a consequence, your website must adequately address an ever-growing need for improvements. Like in flexibility, responsiveness, and conversion optimization.

Fortunately, the cloud has a silver lining; and a bright one at that. Tools to meet these challenges and address them head on are readily available. With the most notable case in point being Be Theme, the largest and most versatile WordPress theme of them all.

With a tool like Be Theme at your fingertips, you’ll be more than able to successfully handle any challenge that comes your way.

Then, it’s simply a matter of following these 5 simple steps to design creative websites. They are eye-catching, impressive in their ability to convert visitors to users and guaranteed to put smiles on your clients’ faces.

5 Steps to Building Astoundingly Creative Websites

Step 1: Choose a Mesmerizing Color Palette

The color palette you use can make a difference between a so-so website and an attention-getting one. Choosing one should not be difficult if you follow a few simple rules:

its colors need to attract instant attention;

they need to be on-brand, and;

the color palette you select needs to visually support the message your app or website is designed to convey

Artist features BOLD color touches that will instantly attract attention.

This Be Theme pre-built website is another great example of what can be accomplished with an eye-grabbing color palette.

Carbon8 is an example of how to align the color palette with the website’s brand. It is done with its clever use of various shades of green. Note how the deep green element draws visitor’s eyes to the center of the page.

BeInsurance features a subtle, crisp color palette. It perfectly reinforces a strategy of using crisp, clear images to gain the clients you need.

BeFestival is a great example of using a color palette designed to appeal to a larger audience.

Step 2: Display Crystal-Clear Photos and Images

This step should be obvious. A crystal clear presentation suggests the business behind it goes the extra mile. That is when it comes to clearly present their products and services. Using the best images you can get your hands on can give you an extra edge over the competition.

BeStylist is an example of the advantage of displaying images with flair. The crisp image definitely supports the intended message.

Or, try something like RansomLTD; minimalist, yet crisp and powerful.

A pre-built website like Zajno illustrates how crystal-clear pics can be used to display your creativity.

The Design Shop employs flair and creativity to entice visitors with crisp and compelling images of your products.

Step 3: Show Visitors How Your Creativity Benefits Them

Creativity isn’t about you. It’s about serving your visitors. It can be extremely effective when it helps them imagine themselves actually using your product or service.

BeMarketing’s homepage video illustrates another way to show people how they can benefit from using your products.

Lane illustrates a fabulous approach you can use to express your structural design perspectives.

BeSimple takes a minimalist approach. It’s the typography and way the text is presented rather than the text itself that’s effective.

BeTravelBlogger provides the basis for a travel blogger’s dream site. You can use it to present your travel adventures and escapades with a super-cool layout of graphics and snippets.

Step 4: (Over)use “White” Space

Yes, it’s true. White space is a design element you can sometimes overuse without causing harm. In fact, in many cases “more is better”, as is obvious in the following examples.

Makespace has a clean design that allows the eye to focus on key elements, imagine, and create.

BeSketch & The Drive New York are two examples where plenty of white space is used to great effect.

When white space is part of the brand it can really help to drive the message home. BeIcecream is an extreme example of how plenty of white space can be used to great effect.

Step 5: Make Your CTAs Grab Them By The Eyeballs

If you don’t have CTA buttons that can’t be ignored, your website isn’t going to convert as many visitors into users as you hoped or planned. You want those buttons to be big, bright, and bold enough to make people feel they absolutely have to be clicked on.

BeDrawing’s CTA button is above the fold as it should be, and it clearly stands out. You can’t help but notice it the instant you’ve finished reading the headline. Its centering on the page makes it serve as a gate that invites visitors to enter.

Stuart makes effective placement and use of 3 clearly defined CTA buttons.

Your CTA can match other elements on the page and still easily attract attention. A great example of this is BeKids, where the color of the button matches the color of other hero section elements.

Building Creative Websites – a Summary

Follow these surefire steps (with the help of a surefire website building tool) and you’re well on your way to satisfying the most demanding of clients. Crisp, stunning visuals, a cleverly chosen color palette and the clever use of white space, images that enable visitors to see themselves using your products, and the all-important bold and beautiful CTA buttons give you the combination for success.

Success typically breeds additional work. Sometimes web design is not as much fun as it used to be. If you suddenly find yourself juggling projects and deadlines to the point you’d be better off using pre-built websites.

You’ll find the most generous gallery of more than 450 creative websites on Be Theme that you can customize to your liking. Start using them now and you’ll never have to worry about juggling projects and deadlines!

White space is the #1 visual element you need to have on your website. That means you need as much space as possible to highlight your creativity.

  Makespace lets you imagine and create. It has a clean design that allows the eye to focus on the most important elements.

You can create a similar creative website with BeSketch or The Drive New York. These are pre-built websites where white space is used to enhance the experience and emphasize the critical elements on the page.

    BeIcecream is perhaps THE most extreme when it comes to white space. It’s part of their brand and it drives the message home like none other.

Step 5: Make your CTAs grab them by the eyeballs

If you want the website to convert visitors into users, then you need CTA buttons they can’t ignore. You’ve got to make the big, bold, and brighter than the sun—this way, you get their attention and compel them to click.

BeDrawing has a CTA button clearly stands out above the fold: it’s got a bold color, big enough to draw your attention to it the second you’re done reading the headline. It’s centered on the page (acting like a “gate” that you need to click to move forward).

Stuart uses clearly defined buttons for the CTA (the one you want your visitors to click).

Another way to direct attention to your CTA is to have it match other elements on the page. A great example is BeKids, where the blue of the CTA button matches some of the visual elements in the hero section.

This curing process takes 24 hours and stores away three kilograms of CO2 per CMU by converting them into a stable mineral, alongside an additional kilogram of CO2 that is pulled from the surrounding air during the curing process.

"The only way CO2 will escape one of our concrete blocks is if somebody burns the block," Sten said. "And nobody does that on purpose."

The resulting carbonated concrete can have up to a 30 per cent higher compressive strength than conventional concrete, the company claims. And since its production process requires no heat, Stern says its energy consumption is "literally not comparable" to that of traditional cement.

System is dependent on steel slag supply

However, the scope of Carbicrete's potential is limited. Currently, its carbon curing process can only take place in the controlled environment of a factory, restricting its use to products such as CMUs and concrete panels that are cast in advance of being delivered to a construction site.

This precludes its use in liquid ready-mix concrete, which is cast and cured on-site to create a building's foundations and floors. To serve this market, Carbicrete is developing a new technology that won't be ready for another five to 10 years.

"It all comes down to how we can make a mobile, flexible curing system and have that on-site," Stern explained.

The technology can so far only be used on precast CMUs and panels rather than ready-mix concrete

Another problem is the supply of steel slag. Only around 250 million tonnes of the industrial byproduct are produced every year compared to four billion tons of cement.

"There's not enough steel slag to make enough concrete to serve the world's needs on a yearly basis," Stern said.

"It's possible to replace 10 to 20 per cent of the current concrete production," he added. "But concrete is the second most-consumed resource on the planet outside of water. So if we make a billion tonnes of concrete, that's a massive amount."

Potential of carbon-cured construction materials 

A number of other companies are exploring alternative methods to reduce the carbon footprint of concrete. Although these solutions are not carbon neutral, they are currently available at a much larger scale.

New Jersey-based Solidia uses carbon instead of water to cure a special cement that is low in lime, reducing CO2 emissions by up to 70 per cent.

Amazon's HQ2 in Arlington will be built using CarbonCure concrete

Meanwhile, Canadian start-up CarbonCure uses captured CO2 emissions to cure regular cement, reducing the amount of cement needed to create a batch of ready-mix concrete and cutting emissions by five per cent.

More than eight million cubic metres of concrete has already been made using the company's technology.

This equates to thousands of buildings, according to CarbonCure's senior director of sustainability Christie Gamble, as will also include "every cubic metre of concrete" in Amazon's new NBBJ-designed headquarters in Arlington, Virginia.

"Carboncure is on a mission to reduce 500 megatonnes of carbon emissions annually by the year 2030," Gamble told Dezeen. "To date, we've been able to reduce over 100,000 tonnes of CO2. We're proud of that reduction so far [but] we still have a long way to go."

CarbonCure injects CO2 into standard concrete mix from a pressurised tank

Elsewhere, UK company Carbon8 Systems has developed a modular technology that fits into a shipping container and can be installed at cement plants to capture their CO2 emissions.

These are then used to cure bypass dust – a powdery byproduct of cement production – creating a "carbon-negative aggregate" that sequesters cement industry emissions while also cutting out the emissions associated with mining and transporting traditional aggregate.

When taken together, UK Concrete estimates that these kinds of carbon capture, utilisation and storage (CCUS) technologies could deliver 61 per cent of the carbon savings the concrete and cement industry claims it needs to make to become net carbon negative by 2050.

"The answer is not that you use CarbonCure or this other sustainability solution," Gamble said. "The answer is: use both and incorporate all of these strategies."
