Lithos Carbon offers a permanent carbon capture solution for farms by leveraging enhanced rock weathering. They utilize crushed basalt rock dust, which not only sequesters atmospheric carbon dioxide through silicate mineral reactions but also enriches soil with essential plant nutrients. Their proprietary machine learning algorithms optimize this process for both maximum crop yield and carbon capture, managing aspects like soil pH regulation and pest resistance. Lithos handles the logistics of feedstock delivery, soil sampling, and application. Their carbon measurement is backed by rigorous research from Yale University and Georgia Institute of Technology, ensuring accurate tracking of captured carbon from farm to ocean. The company's business model involves partnering with farmers, managing the application process, and generating revenue from carbon removal credits sold to corporations, with a revenue-sharing component for the growers.
