Production of cellulosic ethanol from wood sawdust
Web[15]. Sawdust is the major waste from the furniture industry. It is primarily fine chippings of wood produced during sawing or cutting. It contains lignocelluloses and certain amount of moisture [16]. Sawdust serves as a cheap substrate for ethanol production, does not distort the human food chain and takes care of the environmental waste.

Wood Alcohol - Journey to Forever
WebJul 6, 2016 · 2. This is somewhat conjectural, but I think that sawdust is selective in terms of how polar the liquid is. Water and ethanol are both polar, but water significantly more so (ethanol is significantly less nonpolar at the CH3 end). To determine if this is indeed the case, I tried pouring some very low-viscosity (so that it tends to ball up less ...
