Meet the Changemaker Spotlight: Dr. Deborah Aller

Soil Scientist.
Circular Systems Leader.
Evidence-Led Innovator.

Dr. Debbie Aller works where soil health, waste management, and climate action intersect. From early biochar research to leading applied field trials in New York State, her focus has remained clear: translate science into circular solutions that work in the real world.

Her research explores how biochar can transform waste streams into regenerative inputs — improving compost systems, reducing emissions, strengthening soils, and embedding pyrolysis directly into waste infrastructure.
