Write a short article (300 words or so) explaining to another student why biofuels were developed, and why there is a drive towards the use of ethanol as a petroleum (gasoline) substitute and why some American scientists argue that there should be a move away from producing ethanol from corn, towards producing it from cellulose. Give chemical reasons as to why it is more difficult to manufacture ethanol from cellulose than starch.
Biofuels are primarily derived from biomass or bio-waste. Biofuels can be used in a large number of applications, but they have attracted a lot of attention as a possible alternative to petrol in the transport sector. They are thought to be a good way of potentially reducing the emission of greenhouse gases and they can also be considered as a means to reduce the consumption of fossil fuels that are increasingly limited in availability.
Producing ethanol from corn is wasteful and is not sustainable. This is because only a small ...
Why are biofuels being developed? Why is there a drive towards the use of ethanol as a petroleum substitute and why are some American scientists claiming that there should be a move towards producing ethanol from cellulose.
