New Hydrothermal Pretreatment Process Improves Biofuel Production

In Canada, researchers from the University of British Columbia developed a new process to improve how bioreactors break down organic material into methane gas up to 172 percent, which could help lower the cost of biofuels. The new fermentation process, called hydrothermal pretreatment, could be easily implementable and lower costs due to smaller bioreactors. It treats the organic material with carbon dioxide at high temperatures and pressures before it goes into fermentation, and doesn’t require or create toxic chemicals. How effective the process is depends largely on the type of biomass used, with refractory materials like pine residues and Douglas fir bark delivering the best results. While they aren’t ready to bring it to industrial scale, they are hopeful about the results thus far.
