Melbourne-based climate tech startup Kapture has successfully completed trials for carbon dioxide (CO2) sequestration in concrete. This marks a significant achievement in its mission to reduce emissions from both diesel and concrete production.
Addressing Carbon Emissions in the Construction Industry
Kapture, founded in 2022 by Raj Bagri and Jake Youngert, is targeting the construction industry’s carbon footprint. Cement, a core ingredient in concrete, is one of the most carbon-intensive materials used in construction.
The company has developed a process to capture CO2 emissions from combustion sources and embed them permanently into concrete.

Innovative Technology Enhances Concrete’s Strength and Reduces Emissions
Kapture’s CO2 sequestration technology not only reduces emissions but also improves the strength and durability of concrete. The company partnered with Western Australian concrete manufacturer PERMAcast to conduct trials of its carbon-embedded byproduct.
The trials demonstrated substantial reductions in CO2 emissions during concrete production without raising costs.

A Sustainable Solution for the Construction Industry
By replacing part of the traditional concrete ingredients with CO2-embedded byproducts, Kapture directly addresses the emissions from cement production. The technology offsets 0.7 to 1.2 tons of CO2 for every ton of the solvent used during cement manufacturing.
Looking Ahead
CEO Raj Bagri expressed optimism about the technology’s potential. He emphasized that the innovation offers a sustainable solution without compromising cost or performance. Kapture plans to release the byproduct for industry use in 2025, with further trials set for early next year in partnership with an Australian electricity utility.
The startup, which was part of Startmate’s 2023 cohort, initially focused on decarbonizing diesel generators with its low-cost membrane technology. Kapture’s continued success in both concrete and diesel sectors highlights its potential in accelerating emissions reductions across industries.
