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 cement-making process could sharply reduce pollution from one of the world's most carbon-intensive industries. In a study published May 13 in ACS Energy Letters, researchers described an ...

China has witnessed a construction boom and thus an enormous amount of cement use in the past decades. At the same time, cement manufacturing technology has been upgraded rapidly. Here, based on ...

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 ...

Cement producers and their investors are navigating evolving risks and opportunities as the sector’s climate and sustainability implications become more prominent. While many companies now disclose ...

US-based company Vulcan Materials is a major producer of aggregates-based construction materials, including asphalt and ready-mixed concrete. A couple of years ago, the company installed an Insitec ...

Near-zero cement takes a huge bite out of emissions Cement has been a vital building block (pun intended) in constructing civilization. However, its manufacturing process has also made it a wrecking ...

Each year, manufacturers produce around 5 billion tons of portland cement — the gray powder that mixes with water to form the “glue” that holds concrete together. That’s nearly three-quarters of a ton ...

Concrete is everywhere: in buildings, roads, sidewalks, bridges and foundations for almost every structure imaginable. We make more concrete than we do any other material on Earth, and that volume is ...

This process can't avoid producing CO2 – but at least it comes out in a pure, cold state, pre-compressed to 10 bar and ready for easy capture and storage – and using substantially less energy and ...

One technology that is currently directly available is coprocessing in cement manufacturing. This offers a unique waste management solution, where the material is simultaneously used as both a highly ...
