How it works
- Biofuel are liquid or gaseous fuels made from plant or animal material
- Bioethanol is qualifies as a biofuel, because it is made from plants like corn
- To be used as a fuel, bioethanol must be mixed with petrol, and typically a mixture will contain 10% bioethanol and 90% petrol
- It is made from sugary and starchy parts of crops such as sugar cane, corn or wheat
- Bioethanol cannot be used as a fuel on its own
- It can only make up 10% of the fuel
- It has to be mixture with petrol which is the normal car fuel
- There has only be a slightly difference between bioethanol and petrol
- Bioethanol absorbs water from the atmosphere, so it is not a pure ethanol
- It has a lower energy density than fossil fuel, and able to drive fewer miles than normal car fuel
- Bioethanol made from corn in the US has been blamed for driving up the price of corn and other grains.
Implement or not
We believe the company should deliberately think about the advantages and disadvantages of bioethanol first. Do not use the ethanol right ahead, because there is some disadvantages you would like to deliberately think about, and the disadvantages might cause even more terrible things in the future than what had happen to the Earth now. For example, bioethanol cause corn price to rise. Another reason is it only make up 10% of the biofuel, so it is not a big change to our environment.
