The construction sector in the UAE is at the forefront of a drive to use recycling building materials to reduce the damage caused to the environment by traditional methods.
Constructing and running buildings has a major climate impact, accounting for 37 per cent of emissions that cause global warming, according to the UN Environment Programme. Typically, around a quarter of a building’s carbon footprint is accounted for by its construction, with continuing emissions, for heating, cooling and powering appliances, responsible for the remainder.
The UAE, which has a very active construction sector, is involved in efforts to decarbonise buildings. An art and architectural installation called Stoot recently unveiled in the UAE was made with recycled materials from a Swiss company, Oxara, cofounded by Dr Gnanli Landrou, who grew up amid traditional clay-brick and cement houses in Togo in West Africa.
A Dubai design practice, Mula Design Studio, founded by Abdalla AlMulla, an Emirati architect, collaborated in the installation’s creation. Oxara’s patented technology mostly uses construction waste, such as old concrete, brick and excavated material, cutting carbon emissions and the amount of construction waste that ends up in landfill.
"By building Stoot, we proved that the technology and the product is ready to be used, and the performance is positively aligning with what we’re expecting; we’re achieving higher compressive strength. Validation tests are continuing with a local company,” Dr Landrou said.
The material is not suitable for load-bearing parts of high-rise towers, but could be used in non-structural elements in skyscrapers, and for lower-rise buildings.
"This means we’re talking about villas, we’re talking about three or five-storey residential houses, we’re talking about Arabian houses, private villas – that’s where we see the opportunity," Dr Landrou said.
Oxara will enter the Swiss market next year and Dr Landrou said that the technology could be deployed in the UAE within the next six months to a year.
The energy efficiency of buildings is forecast to improve, but a 2023 UNEP report, Building Materials and the Climate: Constructing a New Future, said that efforts to cut emissions from producing and deploying the key things that buildings are made from – cement, bricks, steel and aluminium – have "lagged".
As a result, the embodied carbon of a building will account for a growing proportion of its lifetime carbon footprint, rising from about 25 per cent now to 50 per cent "in the next few decades". There is a need, the report stated, to reduce the "extraction and production of raw materials" by, among other things, reusing building materials.
Making bricks accounts for about 2.7 per cent of global greenhouse gas emissions, mostly from the CO2-generating kilns used to fire them. Cement production is responsible for around eight per cent of emissions because of the kilns that create clinker, a major part of cement, which with water, sand and gravel, makes concrete.
Producing one tonne of cement generates between 561 and 622kg of CO2, according to a study published last year in Renewable and Sustainable Energy Reviews. About 60 per cent of this comes from the decomposition of limestone (which has the chemical formula CaCO3) to calcium oxide (CaO), the study indicated, with a further 30 per cent caused by the burning of fossil fuels to heat the ingredients, and the remaining 10 per cent from powering other equipment.
Sustainable future
Oxara claims that its products cut the carbon emissions associated with standard cement production by up to 90 per cent. What Dr Landrou described as the "massive urbanisation trend" in the global south and emerging economies meant that there was an opportunity in these regions to "define what is the next cement". He indicated that there is enough construction waste in the UAE for the production of the company’s raw materials.
"If we look at Dubai, there’s about 5,000 tonnes of construction and demolition waste that goes to landfill every day. Every year you’re talking about one million tonnes of demolition waste. There’s a huge amount of this resource," he said.
About 70 per cent of solid waste produced in the UAE comes from construction and demolition.
Dr Aseel Takshe, who chairs the Department of Public Health at the Canadian University of Dubai, said that "several promising materials" were being considered for eco-friendly buildings, such as "biomaterials including bamboo, recycled steel and plastics, engineered wood products and precast concrete".
She also said that firms could consider modular and prefabricated construction to reduce waste.
There has been, Dr Takshe said, "a significant push" in the UAE" to strengthen regulations to promote environmentally friendly construction and building design.
"These initiatives demonstrate that the UAE is … encourag[ing] more environmentally construction methods and building design, aligning with global sustainability goals and the country’s vision for a greener future," she said.
The wider picture
Professor Kevin Paine, of the Department of Architecture and Civil Engineering at the University of Bath in the UK, said that within the concrete industry, "there’s a push to clean up their act".
"Everyone I speak to in the concrete industry is very, very keen to be more sustainable, to be as low carbon [as possible]," he said.
He added, however, that he "hadn’t yet seen an alternative that’s good enough at scale" to replace concrete and that reducing its carbon footprint was not easy. If it was, he said that "it would have been done by now".
"I’ve seen technologies that do work in various places that have a good local source of material that will work in a certain way," he said.
"I don’t think there’s a single technology that’s going to replace concrete or change the way concrete is made. There are going to have to be different technologies around the materials that are available."
One issue with the use of recycled building materials to cut the embodied carbon of buildings is limitations in supply where it is needed, he suggested: in fast-developing parts of the world, there may not be enough demolition waste, and shipping such waste in would negate carbon benefits from using it.
At Queen’s University Belfast in Northern Ireland researchers are looking at using waste materials with high silicon dioxide (SiO2) content to replace standard cement, with significant reductions in carbon emissions. Prof Marios Soutsos and colleagues have developed a method to produce sodium silicate powder from waste glass.
"The work we’ve done is with a local waste-collection company," Prof Soutsos said. "The company was keen to convert [the waste glass] into sodium silicate because of the increase in the price of their waste material."
Another way to reduce the carbon footprint of concrete is to use in it a quantity of wollastonite, a calcium silicate mineral that also contains small amounts of aluminium, iron and magnesium.
A study on wollastonite powder published in October in Innovative Infrastructure Solutions found that concrete containing it "exhibited better performance", heralding "a new era of sustainable material for advancing civil engineering infrastructure".
Researchers have also looked at using rice ash husk to replace a portion of the cement in concrete, although the impact on carbon emissions is less dramatic than using recycled materials.

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.”

Going grey? A stylist's advice
If you’re going to go grey, a great style, well-cared for hair (in a sleek, classy style, like a bob), and a young spirit and attitude go a long way, says Maria Dowling, founder of the Maria Dowling Salon in Dubai.
It’s easier to go grey from a lighter colour, so you may want to do that first. And this is the time to try a shorter style, she advises. Then a stylist can introduce highlights, start lightening up the roots, and let it fade out. Once it’s entirely grey, a purple shampoo will prevent yellowing.
“Get professional help – there’s no other way to go around it,” she says. “And don’t just let it grow out because that looks really bad. Put effort into it: properly condition, straighten, get regular trims, make sure it’s glossy.”
Day 5, Abu Dhabi Test: At a glance
Moment of the day When Dilruwan Perera dismissed Yasir Shah to end Pakistan’s limp resistance, the Sri Lankans charged around the field with the fevered delirium of a side not used to winning. Trouble was, they had not. The delivery was deemed a no ball. Sri Lanka had a nervy wait, but it was merely a stay of execution for the beleaguered hosts.
Stat of the day – 5 Pakistan have lost all 10 wickets on the fifth day of a Test five times since the start of 2016. It is an alarming departure for a side who had apparently erased regular collapses from their resume. “The only thing I can say, it’s not a mitigating excuse at all, but that’s a young batting line up, obviously trying to find their way,” said Mickey Arthur, Pakistan’s coach.
The verdict Test matches in the UAE are known for speeding up on the last two days, but this was extreme. The first two innings of this Test took 11 sessions to complete. The remaining two were done in less than four. The nature of Pakistan’s capitulation at the end showed just how difficult the transition is going to be in the post Misbah-ul-Haq era.
