Humanity has long wrestled with how to unlock the carbon stored in agricultural and forestry waste without paying an enormous energetic or chemical toll. A new scientific review proposes that the answer may lie in something already present in many processing environments: mechanical energy itself. By stressing certain materials with vibration or ultrasound, researchers can generate the reactive chemistry needed to break down plant matter into fuels and useful compounds — a quieter, gentler path toward a more circular use of the carbon we already produce.
