Lignocellulosic feedstocks

When will the oil run out? Various estimates put this anywhere from 20 years from now to more than a century in the future. The shortfall in energy might eventually be made up by developments in nuclear fusion, fuel cells, and solar technologies, but what can substitute for gasoline and diesel in all the internal combustion enginepowered vehicles that will continue to be built worldwide until then? And what will stand in for petrochemicals as sources of building blocks for the extensive range of “synthetics” that became indispensable during the twentieth century?...

Finally, to produce an optimal Feed Conversion Efficiency (FCE) for cows and maximise returns, it is vital to combine good rumen function with good nutrition. This report supports the idea that to realistically achieve this goal, dairy farmers should utilise their pastures as a high quality forage base. If and when there is a necessity to supplement the feed ration with higher levels of starch and/or forages, the alternative aforementioned processes could also be undertaken.

The global annual potential bioethanol production from the major crops, corn, barley, oat, rice, wheat, sorghum, and sugar cane, is estimated. To avoid con/icts between human food use and industrial use of crops, only the wasted crop, which is de0ned as crop lost in distribution, is considered as feedstock. Lignocellulosic biomass such as crop residues and sugar cane bagasse are included in feedstock for producing bioethanol as well. There are about 73:9 Tg ofdry wasted crops in the world that could potentially produce 49:1 GL year−1 ofbioethanol.
