Ten cubic kilometres of concrete, equivalent to the volume of Mount Everest, are used in construction projects every year, resulting in huge volumes of emissions. But a new eco-friendly cement may help to reduce...
Scientists at the Swiss Federal Laboratories for Materials Science and Technology (Empa) have developed self-pre-stressed concrete elements. Their innovation makes it possible to build leaner structures that use less material. A team of scientists...
Cement manufacturing accounts for around 7 percent of global CO2 emissions. Alternative types of cement use new ingredients, but the effects of these on performance are largely unexplored. A Swiss research institute hopes to...
MIT researchers have discovered a way to eliminate carbon emissions from cement production, a major source of greenhouse gas emissions. Cement, the world’s leading construction material, accounts for around 8 per cent of all...
Nearly every construction project uses cement. But cement manufacturing consumes the third-most energy among industries worldwide. It’s the second-largest emitter of carbon dioxide, producing around 6 per cent of the primary greenhouse gas causing...
An Australian firm has developed a new technology that can harness carbon dioxide emissions and transform them into eco-friendly building products. It has been operating a pilot plant since the beginning of 2016. Mineral...
While cement manufacturing is one of the most carbon-intensive industrial processes, an international team of researchers has found that the widely used building material eventually reabsorbs much of the CO2 emitted when it was...
Egyptian authorities are planning to build a new coal-fired power plant to improve the country’s energy supply. Environmentalists are campaigning against this. The country’s cement industry depends on coal. And European countries are more...
A Canadian start-up has developed a technology to recycle carbon dioxide gas back into solid concrete, which lowers its carbon footprint. The company looked to natural carbonation reactions for inspiration, such as coral formation...
China used 6.4 gigatons of cement between 2011 and 2013, two gigatons more than the US did over the course of the entire 20th century. Urbanisation and a state-owned cement industry are some of...
A new molecular analysis of concrete’s structure leads to a new formula that would reduce its greenhouse gas emissions and produce better, stronger concrete. Concrete is a leading contributor to global warming, producing between...
A new study shows that mercury levels in the upper oceans are three times higher than they were in the Industrial Revolution times, raising concerns about the amount of mercury in our fish and...
A consortium led by the Swiss Federal Institute of Technology Lausanne (EPFL) has developed a new blend of cement that can reduce the carbon footprint of cement by up to 40 per cent. Applied...
