Biofuel to get new fillip in China, officials say
Posted: Wed, Jul 18 2007. 12:31 AM IST

    The Chinese Government is mandating a shift in ethanol 
production from corn to crops not commonly consumed for food. This 
will ensure no artificial shortage of food products. The 
conversion is predicted to be fairly simple. The new feedstocks 
will consist largely of sweet potato as well as cassava and 
sorghum. Sweet potato and cassava are both high yielding starch 
    However, I feel they may have their own problems. This is 
because sweet potato and cassava's high water content will mean 
they will need to be grown near ethanol production facilities to 
maintain a positive net energy balance.
