12.6 Summary and Final Tasks

Summary

This last lesson covered topics that are practical, such as anaerobic digestion (it is part of digestion), and also topics that are more research-oriented, such as syngas fermentation and microbial fuel cells. The best application for anaerobic digestion is on farms, as a way to utilize waste from animals. Syngas fermentation could be a lower energy-intensive process that could make gasification/syngas fermentation less expensive than using FT synthesis. And, finally, microbial fuel cells are a unique fuel cell that can take advantage of bacteria to make electricity or clean up wastewater inexpensively.
