The future of sustainable mobility: CO₂-absorbing highway that passively captures carbon through a chemical reaction.
Designed according to life's principles
Systems that have evolved over millions of years to be efficient, resilient, and sustainable.
Our inspiration
A range of carbon-absorbing organisms, including tube worms, the saguaro cactus and birds. Each of these organisms has evolved unique strategies for capturing and storing carbon in their environments.
How it works
The highway contains zeolite, a material that absorbs CO₂ from the air as vehicles drive over it. The captured CO₂ is then separated, transported, and filtered into calcium carbonate. This substance can subsequently be reused as a raw material for various products and applications.
Model building
To visualize the construction of the highway and the science behind it, two models were developed. On the left is a scale model of the highway showing the underground system. On the right is a molecular model of zeolite, a natural mineral that absorbs CO₂.
