Summary of Benefits
Cellulosic Ethanol
– No competition with food – Very favorable LCA owing to minimal indirect land usage – Minimal resource inputs in terms of energy, materials, and water – Potential ultimate low cost due to low feedstock cost – Net electrical output due to combusting other waste products (lignin) |
CBP (specifically)
– Lower long term cost since it does not require addition of enzymes, which are expensive – Potential for improvements to throughput and efficiency by engineering organisms (such as C. phytofermentans) |
