Amazon and Brimstone deepen collaboration on eco-friendly cement, achieving successful preliminary testing.
Amazon has announced a significant step towards achieving its sustainability goals by partnering with Brimstone, a company that produces lower-carbon Ordinary Portland Cement (OPC). The e-commerce giant has signed a commercial agreement to reserve annual volumes of Brimstone's OPC and supplementary cementitious materials from Brimstone's upcoming plant in Oakland, California.
The collaboration began with successful third-party tests, designed with Amazon's concrete consultants, which confirmed that Brimstone's OPC meets ASTM C150 standards and performs comparably to conventional cement in key properties such as workability, compressive strength, and durability. Amazon and Brimstone plan to conduct more comprehensive testing through 2025 and 2026, evaluating factors like sulfate resistance and aggregate reactivity across a broader range of concrete mixes and applications.
Brimstone's path to commercialization is well-defined with existing regulation, know-how, and material safety protocols. The company produces ASTM C150 Ordinary Portland Cement, the most widely used cement in the world. Brimstone has developed a more efficient, economical, and sustainable process for producing industry-standard materials, and its cement is available at competitive prices.
The potential benefits of using Brimstone’s lower-carbon cement include reduced carbon emissions from Amazon’s concrete construction, supporting its sustainability and climate goals. The commercially viable lower-carbon cement produced at competitive prices using established regulation and safety protocols will allow Amazon to scale this technology across a large volume of its construction projects.
In summary, Amazon’s future plans involve scaling, testing, and integrating Brimstone’s sustainable cement solutions broadly for building construction, which is expected to drive significant reductions in the carbon footprint of its infrastructure development. The testing phase aims to evaluate durability, sulfate resistance, aggregate reactivity, and other properties across a wider range of mix designs and applications using larger material volumes from Brimstone's Oakland, CA plant.

The partnership between Amazon and Brimstone, focusing on lower-carbon Ordinary Portland Cement (OPC), represents a significant step in the e-commerce giant's environmental-science and sustainability efforts. The collaboration will investigate the use of Brimstone's OPC in business construction projects, potentially reducing carbon emissions while maintaining comparable performance in key properties such as workability, compressive strength, and durability. Expanding this technology, now commercially available at competitive prices, can provide substantial environmental benefits for Amazon's infrastructure development through technology.
