Introduction: Learning From Nature's Genius
Imagine a world where buildings repair their own cracks like healing skin, fabrics change their properties to adapt to temperature like pinecones, and carbon capture happens through materials inspired by seashells.
The Problem
Concrete production alone is responsible for approximately 8% of global emissions and plastic pollution affects every ecosystem 1 .
The Solution
The emerging paradigm looks to nature's circular economy where nothing is wasted and everything serves a purpose.
