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 ...

This strange white paste might not look like much, but it might help solve the sand shortage, while making the cement manufacturing process capture carbon dioxide instead of emitting it. Scientists at ...

The billions of tons of cement made each year have an enormous carbon footprint: 8% of global emissions, or four times more than the airline industry. That’s both because of the energy used to make ...

A photobioreactor, which looks like a large vat of blue liquid with pink light shining, at Prometheus Materials. Stimulated by light, microbes in this bioreactor multiply and react carbon dioxide with ...

Cement production is responsible for around 8% of global carbon emissions. Using microalgae to make a key ingredient could drastically cut that carbon footprint. During a trip to Thailand on his ...

Concrete and steel production are major sources of CO2 emissions, but a new solution from Cambridge could recycle both at the same time. Throwing old concrete into steel-processing furnaces not only ...

The Carbon Cure process - making concrete production safer for the environment. Thomas Concrete is using a new technology called Carbon Cure, which merges science and technology to make the process of ...

It’s a major contributor to climate change — the way buildings and roads are made with concrete. It’s also a problem that’s growing as more of the world develops. So the race has been on to find ...
