Holy Sh*t: Building the Circular Bionutrient Economy with Biochar

Around the world, nutrient surpluses from livestock and sanitation systems are creating environmental headaches, while farmers and ecosystems struggle with nutrient scarcity. It’s time to close the loop.

In this webinar, Dr. Johannes Lehmann dives into how biochar technology can how biochar technology can underpin the circular bionutrient economy as a valuable resource for soil, crops, and the climate. You’ll learn how pyrolysis can drastically reduce waste volume and weight, capture nutrients in dry, transportable forms, and even recover nitrogen at meaningful scales.

Dr. Lehmann will also explore how biochar-based fertilizers can become cost-competitive when environmental benefits are factored in through carbon credits, market innovation, and life-cycle optimization. Building the circular bionutrient economy demands public-private partnerships and green alliances ready to turn “waste” into opportunity.
