ARCA’s first commercial projects are to recover the byproducts of ming (missinealings and rock rock), to accelerate the natural process of the area called carbon mineralization, the conversion of gaseous co₂ in solid mineral form. In doing so, arca delivers a measurable, independently verified, and sustainable carbon footprint while making my waste safer, and creating jobs in the communities it hosts.

Why industrial minerals matter

Content of the article

Most industrial wastes such as feedstocks: Billions of Tonnets of industrial byproducts are already in the world.
Light step: There are many opportunities to integrate into existing industrial sites, with low energy, land and water needs.
Earth’s Strength: Removes co₂ For Millenia, with ROVUT MRV to ensure clarity.
Benefits of industry-community cooperation: It reduces environmental risks, creates jobs in host communities, and turns waste liabilities into valuable assets.
