Nature’s way of building—now engineered for the future.

Limestone has been locking away carbon for millions of years, naturally cycling it through the Earth’s ecosystems. Conventional cement-making disrupts this cycle—burning limestone at 1,450°C releases its stored carbon straight into the atmosphere.

At Biozeroc, we turn this process on its head. Inspired by how corals grow in the ocean, we use bacteria to grow limestone crystals. We deploy these crystals to bind aggregate together—just like cement does—but storing carbon instead of releasing it.

The result? A next-generation, carbon-negative cement: BioCement.

why Limestone?

Limestone is one of the world’s most time-tested building materials. It’s durable, versatile, and helps regulate temperature naturally. Here’s why it makes the perfect binder:

  1. Exceptionally durable
    Limestone has been used in construction for thousands of years—standing strong against weathering. While it does naturally corrode over time, the corrosion is superficial and won’t impact its structural integrity.

  2. Premium finish & versatility
    Our limestone-based binder is naturally white, making it a seamless replacement for white cement. Prefer a different look? We’ve got options.

  3. Built-in climate control
    Limestone absorbs and releases heat efficiently, helping keep spaces cool in summer, warm in winter—reducing energy costs and carbon footprints.

Limestone in History

Great architecture stands the test of time. These iconic limestone structures showcase the materials durability and legacy:

  • The Great Pyramid of Giza (4,600 years old)

  • The Parthenon (2,500 years old)

  • The Great Sphinx (4,500 years old)

  • The Colosseum (2,000 years old)

  • The Empire State Building (100 years old) – Featuring 5,700m³ of limestone in its iconic exterior
