[biofuelwatch] Bagasse for cellulosic ethanol



As far as I can make out, from the story about China investing in many biofuel plants in Nigeria, using largely bagasse. It seems bagasse comes from the remains of the sugar, or sorghum plants, once the food part of the plant has been extracted.

So this is not actually using food to make fuel, but using the crop residues.

Presumably the residues could be used to heat things locally, or fuel the sugar refinery etc, instead of making biofuels for China. But apart from that use, is this quite a good way to produce biofuel, from residue that would otherwise biodegrade and produce carbon anyway?

Or are they actually using the food parts of the plants for biofuel as well?

There is an article about this at http://www.ncsu.edu/bioresources/BioRes_03/BioRes_03_2_0452_Dawson_B_Cellulosic_Ethanol_Bagasse.pdf

Biofuels are a wide range of fuels which are in some way derived from biomass.

Your idea?
