Alterbiota

alterBiota is a concrete technologies company focused on cost-effective modernization and decarbonization of concrete — one of the world’s most important and carbon-intensive materials. Our patented process converts biochar produced from sustainable forestry waste into deltaC (∆C™), a renewable, drop-in liquid admixture that enhances concrete performance and reduces embodied carbon by up to 30%. Acting as a micro-filler, ∆C™ improves strength and enables lower-cement mixes while supporting scalable, low-carbon concrete production. As legacy industries like forestry and concrete transform with closures of pulp mills, steel blast furnaces, and coal fired power plants, ∆C™ offers a new paradigm for a scalable, value-added circular economy. Our digital platform, digitalΔggregate™, uses computer vision to capture aggregate size, shape, and gradation data, both in the field using a smartphone and inline during batching through our durable vision systems. It enables continuous quality control, mix optimization, and unparalleled visibility into material performance far beyond what traditional testing methods can provide. Together, ∆C™ and digitalΔggregate™ enable the future of precision concrete that is smarter and more sustainable — driving a circular, low-carbon future without a green premium.
