About
Starstone is an Israeli startup founded in 2023, based in Rehovot, that is transforming the concrete industry by utilizing biological building blocks to produce biology-based cement. Their innovative approach aims to significantly reduce CO2 emissions associated with traditional cement and concrete production, which is a major contributor to global emissions. The company's solution will not require quarries or kilns, thereby reducing the production value chain and offering a scalable and cost-efficient approach. Starstone is currently working on a non-loadbearing precast concrete MVP, estimated to be commercially ready by 2026/2027.
