Solid Carbon is a selected participant in a Green Concrete Testing Program on behalf of a major global hyperscaler that is aggressively searching for low-carbon concrete solutions that can scale to data center demand worldwide. The program is designed to move beyond “labcrete” by combining literature review, lab testing, truck trials, and full-scale mock-ups to prove out mixes that deliver both deep carbon reductions and real jobsite performance.​​

In this collaboration, an independent third-party technical lead, is benchmarking embodied carbon, coordinating testing, and validating constructability so the hyperscaler can confidently deploy new mix designs across a rapidly growing global portfolio. Their goal is not just a few showcase pours, but a repeatable playbook for low-carbon concrete that can be replicated across many regions and contractors.​

Solid Carbon’s contribution centers on engineered, carbon-negative ingredients such as biochar-based additives that permanently store biogenic carbon in the concrete matrix while enabling significant reductions in cement content and overall Global Warming Potential. For this project we contributed both BioLOCK 2.0 and BioPOZZ along with the technical advice and guidance on how to batch with our materials. These materials are a key component of the broader roadmap to carbon neutrality in concrete, complementing clinker reduction, alternative binders, and performance-based specifications.​

As the industry pushes toward ever-lower embodied carbon targets for mission-critical facilities, carbon-negative technologies like biochar move from “nice-to-have” to essential infrastructure. By turning slabs and foundations into durable carbon sinks at this scale, the program is demonstrating how next-generation concrete can help the sector meet aggressive climate commitments without slowing down construction.​​

For Solid Carbon, participation in this program is both a proving ground and a launchpad: every successful truck trial and field pour helps de-risk adoption, refine mix guidance, and build the evidence needed to roll out carbon-storing concrete wherever the hyperscaler builds next. It is a pivotal step toward a future where high-performance concrete is not just low carbon—but actively part of the carbon removal toolkit for the built environment.
