Large-Scale Biochar Production from Crop Residue: A New Idea and the Biogas-Energy Pyrolysis System

Shenqiang Wang, Xu Zhao, Guangxi Xing, Linzhang Yang

Abstract


Biochar is an effective means to withdraw carbon dioxide (CO2) from the atmosphere and consequently influence the trend of global climate change. However, there still are substantial knowledge gaps for this idea to be applicable. One big question is how to produce biochar from biomass on a large scale. Our idea is to use biogas produced from agricultural wastes as thermal energy for biochar production from cheap crop residues. A continuous biogas-energy pyrolysis system has been designed and successfully piloted to utilize crop residues for biochar production.
