Melbourne-based climate tech startup Kapture has announced the successful completion of carbon dioxide (CO2) sequestration trials in concrete, a major milestone in its mission to reduce emissions from diesel and concrete production.
Founded in 2022 by Raj Bagri and Jake Youngert, Kapture aims to tackle one of the construction industry’s most significant challenges: the carbon footprint of cement.
The company has developed a process to capture and store carbon dioxide (CO2) emissions from combustion sources, embedding the CO2 permanently into concrete.
This innovative approach not only lowers emissions but also enhances the strength and durability of the material.
In partnership with Western Australian concrete manufacturer PERMAcast, Kapture conducted trials to evaluate the performance of its carbon-embedded byproduct under real-world conditions.
The results exceeded expectations, demonstrating significant reductions in the CO2 footprint of concrete production without increasing costs.

Kapture’s technology replaces a portion of traditional concrete ingredients with the carbon-embedded byproduct, addressing the emissions associated with cement, one of the most carbon-intensive construction materials.
For every ton of the company’s solvent used, 0.7 to 1.2 tons of CO2 emissions are offset during cement production.
Kapture’s successful trials are a pivotal step in decarbonizing one of the most emissions-intensive industries, CEO Raj Bagri said, adding that the technology delivers a sustainable solution without compromising on cost or performance.
The byproduct is slated for industry use in 2025, and Kapture is preparing for further trials with an Australian electricity utility in early 2025. Details of this initiative will be announced soon.
The startup was part of Startmate’s 2023 cohort and initially focused on decarbonizing diesel generators with its low-cost membrane technology.
