(Phys.org) -- While the largest contributor to anthropogenic greenhouse gas emissions is the power industry, the second largest is the more often overlooked cement industry, which accounts for 5-6% of ...
One of the biggest problems in dealing with carbon dioxide emissions is the making of the key component of cement: lime (calcium oxide). Now, a small company with the cute name Sublime Systems appears ...
Scientists are proposing a new way to make cement by replacing limestone with volcanic rocks like basalt, a shift they say could dramatically cut emissions tied to one of the world’s dirtiest ...
A new technique can produce cement using waste from demolished buildings, which researchers say could save billions of tonnes of carbon by 2050. “We have definitely proved that cement can be recycled ...
The company says it can produce all sorts of goods from one type of rock, unlocking a new “industrial revolution.” ...
Researchers at the University of British Columbia have developed a new cement production process powered by electricity. This method cuts carbon dioxide emissions by up to 98 percent and uses 70 ...
Cement is necessary for making concrete, which is foundational in constructing buildings and infrastructure around the globe because it is relatively low-cost, strong and durable. But making cement ...
Researchers on Wednesday said they were a step closer to solving one of the trickiest problems in tackling climate change—how to keep making cement despite its enormous carbon footprint. In a world ...
Not only could the new process help sequester CO 2 from the ever-warming atmosphere, it also results in concrete with uncompromised strength and durability. "More interestingly, this approach to ...
Norway’s Statoil saves hundreds of millions of euro in avoided carbon taxes by using CCS. Since 1996, the Sleipner gas field has stored about one million tonnes CO2 a year. A second project in the ...
