Briefings

A researcher named Karen Antorveza Paez at the Department of Architecture at ETH Zurich is developing a method where bacteria bond sand grains to create solid building elements, replacing high-temperature rock firing. This approach aims to reduce CO2 emissions in construction by avoiding the combustion of rocks. The project is still in early research phases with no commercial products available yet.

Key points

• Karen Antorveza Paez, who holds a doctorate from ETH Zurich, is leading research at the Department of Architecture to develop bacterial bonding for sand construction.
• The proposed method avoids firing rocks at over 1,000°C, aiming to significantly lower CO2 emissions compared to traditional cement manufacturing.

Context and limitations

This is a preprint research article from October 2026. No commercial products exist yet, and the specific bacterial strains, growth conditions, and long-term durability data are not provided.
