Carbon capture and mineralisation for restorative infrastructure
An end-to-end solution making low carbon built environments viable.
%
of the world’s total CO2 emissions stay directly in the atmosphere.
In order to combat climate change, we need to remove CO2 from the atmosphere.
%
of the world’s CO2 emissions come from cement. It’s time to do something about it.
We’ve created a low-carbon cement replacement solution that simultaneously removes CO2 from the atmosphere.
In order to reach Net Zero emissions, we need solutions which counteract these effects – Earth Repair is one of these.
Cement manufacturing is responsible for most of the emissions in the concrete value chain. This calls for an overhaul of the concrete manufacturing industry’s reliance on Ordinary Portland Cement in a bid to reduce global CO2 emissions and hit Net Zero targets – Earth Repair can lead this industrial change.
Created entirely from feedstocks, such as ground natural minerals, and CO2 captured from the atmosphere, Earth Repair’s carbonated residue, a supplementary cementitious material (SCM), replaces the use of Ordinary Portland Cement (OPC) in the concrete manufacturing process.
Key Advantages
High-integrity removals
Fast & measurable CO2 removals, not just avoidance
Permanent CO2 storage
Stores captured CO2 as a concrete replacement
Low energy intensity
Less than 175 kWh per ton of CO2 captured and sequestered
Scalable solution
Low cost & efficient removals, plenty of feedstock
Diversified revenue
Advantageous economics for both SCM & CO2 markets
Displaces cement
Avoids emissions from the cement industry
Our SCM meets the ASTM standard.
Read about just one of the ways in which Earth Repair’s SCM meets these targets and get in touch for further information on how we achieve this.
Highly Scalable
With ground natural minerals, there is virtually limitless CO2 removal potential.
On-shore ground basalt alone has the potential to mineralise 130,000 Gt of CO2, while we would only emit 18,500 Gt of CO2 if we were to burn all available fossil fuels in Earth’s crust.
Earth Repair’s process is extremely energy efficient.
We need less than 200 kWh of electricity to capture and sequester a ton of CO2, which is an order of magnitude less than the competition.
Earth Repair’s Competitive Advantages
The Earth Repair process carbonates a feedstock to manufacture a carbonated residue which can be used in the concrete industry. This carbonated residue is a supplementary cementitious material or SCM. Our SCM replaces up to 30% of cement while improving the performance of concrete.
Earth Repair’s process improves both the quality and consistency of the feedstock to manufacture a valuable product for the concrete industry.
How we can outperform other low-carbon concrete providers.
- Earth repair is efficient from a resource perspective, such as low energy intensity and use of waste materials.
- Our product caters for the total concrete market, and is not a sub-set of this market such as the pre-cast market.
- Our process captures the CO2 from the atmosphere – it does not need a point-source of CO2. This both facilitates scalability and delivers high-quality carbon removal credits, which are typically of higher value than offset credits.
- The permanent store solution is embedded in the technology – there is no need for a geological store commonly found in the CCS industry.
- Under certain circumstances, Earth Repair could enable a negative carbon concrete, provided the cement could hold a large proportion of SCM produced by Earth Repair.
