The role of biochar on alleviating ammonia toxicity in anaerobic digestion of nitrogen-rich wastes: A review.

Published in Bioresource technology

This paper reviewed the mechanisms of biochar in relieving ammonia inhibition. Biochar affects nitrogen-rich waste's anaerobic digestion (AD) performance through four ways: promotion of direct interspecies electron transfer (DIET) and microbial growth, adsorption, pH buffering, and provision of nutrients. Biochar enhances the DIET pathway by acting...
