New London site locks CO2 in recycled concrete for carbon removal
Innovative project captures and stores carbon dioxide in concrete mix
A new project in London is recycling construction waste into concrete that captures and stores carbon dioxide. The project, which is being led by the University of East London and Imperial College London, is using a groundbreaking process that involves capturing carbon dioxide from the atmosphere and then injecting it into recycled concrete mix.
How does it work?
The process starts by capturing carbon dioxide from the air using a technology called direct air capture (DAC). DAC uses a chemical process to bind the carbon dioxide in a solid form, such as calcium carbonate. The solid form is then mixed into recycled concrete, where it reacts with the other ingredients to create a strong and durable material.
The recycled concrete not only has the potential to reduce carbon dioxide emissions, but it also has a number of other benefits. It is stronger and more durable than traditional concrete, making it ideal for use in construction projects that require a high level of strength and resilience.
What are the benefits?
The new carbon-capturing concrete has a number of benefits, including:
- Reduced carbon dioxide emissions: The process of capturing carbon dioxide from the air and storing it in concrete helps to reduce carbon dioxide emissions, which is a major contributor to climate change.
- Increased strength and durability: The carbon-capturing concrete is stronger and more durable than traditional concrete, making it ideal for use in construction projects that require a high level of strength and resilience.
- Reduced construction costs: The use of recycled concrete can help to reduce construction costs, as it is less expensive than traditional concrete.
- Improved air quality: The process of capturing carbon dioxide from the air helps to improve air quality, which is beneficial for human health and the environment
