CarbonFree is a mid-sized environmental services company based in San Antonio, Texas, focused on reducing emissions in hard-to-abate industrial sectors. It was founded on the principle that environmental impact and economic durability should advance together, and its SkyMine technology has operated commercially since 2016 to demonstrate carbon mineralization at scale. The company’s SkyCycle platform builds on that foundation by converting captured CO2 into high-purity calcium carbonate, using industrial co-products such as steel slag to support a circular solution, with installation, operation, and maintenance services for its customers. Its offerings target industrial clients pursuing decarbonization and resource recovery, delivering materials used across packaging, coatings, pharmaceuticals, and consumer goods. Within the environmental services industry, CarbonFree positions itself as a provider of carbon capture and utilization that couples emissions reduction with waste-stream repurposing. In late 2025, the company announced a distribution partnership with Univar Solutions USA LLC to explore distributing its endurocal calcium carbonate.
