WHAT IS CAPTURECRETE®?

The concrete industry contributes to approximately 8% of global CO2 emissions, primarily stemming from cement production.

Carbon Limit’s CaptureCrete® is an innovative solution that combines Direct Air Capture (DAC) technology with CO2 mineralization to reduce the carbon footprint of concrete significantly. CaptureCrete® puts carbon-capturing technology directly into the hands of cement & concrete manufacturers. They can license the formula to create the additive on-site and use it in any concrete.


Furthermore, every time CaptureCrete® is used in concrete it generates high quality carbon credits of 1000+ year permanence. Carbon Limit’s forward credits
are validated by Bureau Veritas under Covalent’s Certification Standard, and are available for pre-purchase.

how
it works

CaptureCrete® is a proprietary blend of natural minerals and CO₂-reactive materials that absorbs and permanently sequesters atmospheric CO₂ in concrete, via mineralization.

FOOTPRINT

Dual decarbonization: Pre-cure at point ofmanufacturing and post-cure as concretestarts capturing CO₂  from the atmosphere.

Atmospheric CO₂ reduction & storage

Concrete made with CaptureCrete® actively attracts CO₂ pollution from the surrounding atmosphere and stores it permanently via CO₂ mineralization.

CaptureCrete® is available in two forms, designed to harmonize with a wide spectrum of concrete products and mix designs

how to use it

1
Source CaptureCrete® material, as you would Fly ash, Slag, or other materials.
2
Blend and add CaptureCrete® to your product mix.
3
Deploy CaptureCrete® concrete, the rest is business per usual.

MAKING THE INVISIBLE
VISIBLE

The images show three samples that were exposed to the same amount of CO2. 

A phenolphthalein solution was used to assess the extent of carbonation. The areas which are not pink are the carbonated areas.

CARBON FOOTPRINT REDUCTION

Carbon capture and sequestration in concrete using CaptureCrete® can reach as much as 100 kg of CO2 per ton of concrete.

Employing CaptureCrete® SCM also offsets the CO2 emissions of the replaced conventional cement.

In total, using CaptureCrete® could potentially reduce the concrete's CO2 footprint by as much as 75%.
