A method which could revolutionise the production of concrete and slash emissions in the global building industry has been developed.
Concrete is the world’s most-used material, with 500kg produced for every person on the planet, a year.
But it is also hugely energy intensive, and responsible for about 7.5 per cent of emissions.
The process was discovered by the University of Cambridge and used electrically-powered arc furnaces for steel recycling to simultaneously recycle cement, the carbon-hungry component of concrete, which is responsible for almost 90 per cent of its emissions.
The researchers behind the discovery describe it as “an absolute miracle”.
They proved how used cement can serve as a replacement for a material called lime flux during the steel recycling process. Lime flux, which removes impurities in the steel, would normally end up as a waste product. But in replacing it with used cement, the cement is also recycled and can be used to make new concrete.
Concrete is a mixture of four things – cement, sand, stones and water.
Professor Julian Allwood from Cambridge’s Department of Engineering, who led the research, told The National: “Cement is the active ingredient and the one that’s associated with all the emissions.”
That is because it is made through a process called clinkering, where limestone and other raw materials are crushed and heated to about 1,450°C in large kilns.
“That’s such a high temperature that you essentially have to reach it by burning fossil fuels. So combustion emissions is about half of the emissions,” said Prof Allwood.
“But the other is the chemistry of converting limestone into cement automatically releases carbon dioxide into the atmosphere. That is the other half of the emissions.
“So the cement has already given up its Co2. There is no new chemical reaction required. In effect what we are doing is reactivating the cement.”
He said his team were motivated to seek a solution to the problem because although there are some options for making cement with less emissions, there are none for making the material with zero emissions.

“And yet the UK, and many other countries, rightly, are committed to zero emissions in the relatively near future.
“Without it means no cement and building with other very limited options,” he added.
Tests carried out by the Materials Processing Institute, a partner in the project, showed that recycled cement can be produced at scale using an electric arc furnace.
But the researchers say it could produce zero emission cement, if the electric arc furnace is powered by renewable energy.
“The important thing is that for the first time there is a route to getting to zero emissions cement. Our estimate of the maximum volume we could make is based on the fact that we know the world’s steel recycling industry will double in size, at least, in the next 30 years,” said Prof Allwood.
“Because the supply of scrap steel has gone up. If we assume that all of them use our process, we could maybe get up to a quarter of today’s supply of cement.”
You could look at that in two ways, he said.
“One is to say oh where is the other three quarters going to come from? But the better way to look at it is all the rest of it is going to have to stop because of our commitment to getting to zero emissions. At least we now have an option for having some cement,” added Prof Allwood.
Earlier this month, it was revealed that researchers aim to harness heat generated by the sun to manufacture building materials such as glass, steel, ceramics and cement, showing that generating heat of 1,000°C heat is possible without using fossil fuels.
They have found a way to improve the efficiency of solar receivers, which concentrate and build heat with thousands of sun-tracking mirrors.
Researchers led by a team in Switzerland used quartz to trap sunlight, in a process known as the thermal-trap effect, proving a receiver with a normal efficiency of 40 per cent at 1,200°C that uses a concentration of light from 500 suns can hit 70 per cent efficiency when shielded with 300mm of quartz. To obtain that performance would normally require the light from 1,000 suns.

'Worse than a prison sentence'
Marie Byrne, a counsellor who volunteers at the UAE government's mental health crisis helpline, said the ordeal the crew had been through would take time to overcome.
“It was worse than a prison sentence, where at least someone can deal with a set amount of time incarcerated," she said.
“They were living in perpetual mystery as to how their futures would pan out, and what that would be.
“Because of coronavirus, the world is very different now to the one they left, that will also have an impact.
“It will not fully register until they are on dry land. Some have not seen their young children grow up while others will have to rebuild relationships.
“It will be a challenge mentally, and to find other work to support their families as they have been out of circulation for so long. Hopefully they will get the care they need when they get home.”

Rating: 3.5/5
Mercer, the investment consulting arm of US services company Marsh & McLennan, expects its wealth division to at least double its assets under management (AUM) in the Middle East as wealth in the region continues to grow despite economic headwinds, a company official said.
Mercer Wealth, which globally has $160 billion in AUM, plans to boost its AUM in the region to $2-$3bn in the next 2-3 years from the present $1bn, said Yasir AbuShaban, a Dubai-based principal with Mercer Wealth.
“Within the next two to three years, we are looking at reaching $2 to $3 billion as a conservative estimate and we do see an opportunity to do so,” said Mr AbuShaban.
Mercer does not directly make investments, but allocates clients’ money they have discretion to, to professional asset managers. They also provide advice to clients.
“We have buying power. We can negotiate on their (client’s) behalf with asset managers to provide them lower fees than they otherwise would have to get on their own,” he added.
Mercer Wealth’s clients include sovereign wealth funds, family offices, and insurance companies among others.
From its office in Dubai, Mercer also looks after Africa, India and Turkey, where they also see opportunity for growth.
Wealth creation in Middle East and Africa (MEA) grew 8.5 per cent to $8.1 trillion last year from $7.5tn in 2015, higher than last year’s global average of 6 per cent and the second-highest growth in a region after Asia-Pacific which grew 9.9 per cent, according to consultancy Boston Consulting Group (BCG). In the region, where wealth grew just 1.9 per cent in 2015 compared with 2014, a pickup in oil prices has helped in wealth generation.
BCG is forecasting MEA wealth will rise to $12tn by 2021, growing at an annual average of 8 per cent.
Drivers of wealth generation in the region will be split evenly between new wealth creation and growth of performance of existing assets, according to BCG.
Another general trend in the region is clients’ looking for a comprehensive approach to investing, according to Mr AbuShaban.
“Institutional investors or some of the families are seeing a slowdown in the available capital they have to invest and in that sense they are looking at optimizing the way they manage their portfolios and making sure they are not investing haphazardly and different parts of their investment are working together,” said Mr AbuShaban.
Some clients also have a higher appetite for risk, given the low interest-rate environment that does not provide enough yield for some institutional investors. These clients are keen to invest in illiquid assets, such as private equity and infrastructure.
“What we have seen is a desire for higher returns in what has been a low-return environment specifically in various fixed income or bonds,” he said.
“In this environment, we have seen a de facto increase in the risk that clients are taking in things like illiquid investments, private equity investments, infrastructure and private debt, those kind of investments were higher illiquidity results in incrementally higher returns.”
The Abu Dhabi Investment Authority, one of the largest sovereign wealth funds, said in its 2016 report that has gradually increased its exposure in direct private equity and private credit transactions, mainly in Asian markets and especially in China and India. The authority’s private equity department focused on structured equities owing to “their defensive characteristics.”

Tributes from the UAE's personal finance community
• Sebastien Aguilar, who heads SimplyFI.org, a non-profit community where people learn to invest Bogleheads’ style
“It is thanks to Jack Bogle’s work that this community exists and thanks to his work that many investors now get the full benefits of long term, buy and hold stock market investing.
Compared to the industry, investing using the common sense approach of a Boglehead saves a lot in costs and guarantees higher returns than the average actively managed fund over the long term.
From a personal perspective, learning how to invest using Bogle’s approach was a turning point in my life. I quickly realised there was no point chasing returns and paying expensive advisers or platforms. Once money is taken care off, you can work on what truly matters, such as family, relationships or other projects. I owe Jack Bogle for that.”
• Sam Instone, director of financial advisory firm AES International
"Thought to have saved investors over a trillion dollars, Jack Bogle’s ideas truly changed the way the world invests. Shaped by his own personal experiences, his philosophy and basic rules for investors challenged the status quo of a self-interested global industry and eventually prevailed. Loathed by many big companies and commission-driven salespeople, he has transformed the way well-informed investors and professional advisers make decisions."
• Demos Kyprianou, a board member of SimplyFI.org
"Jack Bogle for me was a rebel, a revolutionary who changed the industry and gave the little guy like me, a chance. He was also a mentor who inspired me to take the leap and take control of my own finances."
• Steve Cronin, founder of DeadSimpleSaving.com
"Obsessed with reducing fees, Jack Bogle structured Vanguard to be owned by its clients – that way the priority would be fee minimisation for clients rather than profit maximisation for the company.
His real gift to us has been the ability to invest in the stock market (buy and hold for the long term) rather than be forced to speculate (try to make profits in the shorter term) or even worse have others speculate on our behalf.
Bogle has given countless investors the ability to get on with their life while growing their wealth in the background as fast as possible. The Financial Independence movement would barely exist without this."
• Zach Holz, who blogs about financial independence at The Happiest Teacher
"Jack Bogle was one of the greatest forces for wealth democratisation the world has ever seen. He allowed people a way to be free from the parasitical "financial advisers" whose only real concern are the fat fees they get from selling you over-complicated "products" that have caused millions of people all around the world real harm.”
• Tuan Phan, a board member of SimplyFI.org
"In an industry that’s synonymous with greed, Jack Bogle was a lone wolf, swimming against the tide. When others were incentivised to enrich themselves, he stood by the ‘fiduciary’ standard – something that is badly needed in the financial industry of the UAE."
So what is Spicy Chickenjoy?
Just as McDonald’s has the Big Mac, Jollibee has Spicy Chickenjoy – a piece of fried chicken that’s crispy and spicy on the outside and comes with a side of spaghetti, all covered in tomato sauce and topped with sausage slices and ground beef. It sounds like a recipe that a child would come up with, but perhaps that’s the point – a flavourbomb combination of cheap comfort foods. Chickenjoy is Jollibee’s best-selling product in every country in which it has a presence.
