The mandated demand for bioethanol in Australia and overseas is currently limited by the availability of sugar based feedstocks, meaning that Agave can make a significant contribution to a low-carbon future, especially utilising marginal lands.
The best energy crops will maximize the amount of biomass that can be grown per hectare, with least inputs and although the greatest attention is currently on ethanol, sugars from agave energy crops could also be processed into a number of alternative fuels.
Bioethanol, is ethanol sourced from biological sources and is principally produced by fermentation of starch or sugars, but increasingly there will be more produced from cellulosic feedstocks, thus significantly increasing yields from biomass.
Agave low-lignin cellulose fibre has high levels of sugars and is a candidate for Generation 2 technology ethanol production from cellulose. Of the new crops or processes proposed for ethanol production, certain Agave varieties are the only new energy crop ready to go into the ground now. Apart from corn, sorghum and sugar cane, most other potential ethanol-generating crops are years away from field tests. Clearly, a demand for low input ethanol-producing feedstocks exists now.
