Briefings

Researchers at ETH Zurich developed a method where bacteria bind sand grains to create a solid, building-grade cement alternative. This process replaces traditional cement, offering a potential solution for sustainable construction materials. The study was published in October 2026, marking a significant step in bio-based materials science.

Key points

• Bacteria are used to bind sand grains together to form a solid cement-like material.
• The process offers an alternative to conventional cement for construction applications.

Context

ETH Zurich researchers have developed a bio-based construction material using bacteria to bind sand grains into a solid cement alternative, replacing traditional cement for sustainable building applications.

Limitations

The study is a preprint with limited scope; specific performance metrics, scalability data, and long-term durability results are not provided.
