Climate alchemy: Team turns carbon dioxide into super-strong fibers

In an effort to mitigate human-caused climate warming, scientists are focused on ways to remove carbon dioxide from the atmosphere. One of the more novel ways to do this has just been announced by scientists at the Brookhaven National Laboratory (BNL) … Continue reading Climate alchemy: Team turns carbon dioxide into super-strong fibers

Revolutionary “true zero carbon” cement uses electrolysis, not furnaces

Traditional concrete manufacturing processes result in a ton of CO2 for every ton of cement produced – and since we’re talking about somewhere around 4.1 billion tons globally just in 2022 – more than half of that in China alone – cement is a massive c… Continue reading Revolutionary “true zero carbon” cement uses electrolysis, not furnaces

New recipe makes concrete that absorbs more CO2 than it emits

Concrete is one of the most common materials on Earth, thanks to its high strength and low cost – but it’s also one of the largest single sources of carbon dioxide emissions. Engineers at Washington State University (WSU) have developed a new method fo… Continue reading New recipe makes concrete that absorbs more CO2 than it emits

Factory-sized facility being built to produce carbon-negative concrete

Concrete has been used in construction for thousands of years, it’s everywhere. But its production is a major contributor to global carbon emissions, and we’ve seen much research aimed at reducing its environmental impact. One such project spun out of … Continue reading Factory-sized facility being built to produce carbon-negative concrete

Green new concrete recycles building waste and captured CO2

Concrete is the most widely used building material in the world, but it comes at a huge environmental cost. Engineers in Japan have developed a new technique to make concrete by recycling waste concrete and combining it with captured carbon dioxide.Con… Continue reading Green new concrete recycles building waste and captured CO2

Novel cement uses discarded clay to cut carbon footprint by two thirds

As a widely used material across the globe, cement has a massive environmental footprint and accounts for around eight percent of our CO2 emissions, but scientists hope to eat into this problem by making tweaks to the recipe. A research team has now co… Continue reading Novel cement uses discarded clay to cut carbon footprint by two thirds

Self-healing concrete eats CO2 to fill its own cracks in 24 hours

Concrete has a massive carbon footprint, so technologies that boost its performance and enable it to last longer could have profound benefits for the environment. This has led to the development of self-healing concrete that can repair its own cracks, … Continue reading Self-healing concrete eats CO2 to fill its own cracks in 24 hours

World’s first graphene-enhanced concrete slab poured in England

As the mostly widely used material on Earth, concrete has a massive carbon footprint that scientists are working to chip away at in all sorts of ways. Recent research projects have demonstrated how the wonder material graphene could play a role in this… Continue reading World’s first graphene-enhanced concrete slab poured in England

Eco-friendly concrete swaps out sand for activated clay

Given its status as the most widely-used manufactured material on Earth, reducing the huge environmental footprint of concrete would have significant consequences for the health of the planet. Researchers at the National University of Singapore (NUS) h… Continue reading Eco-friendly concrete swaps out sand for activated clay

Fresh recipes for low-carbon concrete take out $20-million XPrize

A six-year competition to capture CO2 emissions from operational power plants and convert them into useful products has drawn to a close, and produced dual winners with technologies that promise to reduce the environmental footprint of concrete. The US… Continue reading Fresh recipes for low-carbon concrete take out $20-million XPrize
