Bioethanol is a fuel derived from renewable sources of feedstock. It is primarily created through a sugar fermentation process. Energy crops are the main sources of sugar required to create ethanol. Examples of these crops are corn, maize and wheat crops, waste straw, willow and popular trees, sawdust, reed canary grass, cord grasses, jerusalem artichoke, myscanthus and sorghum plants. Since bioethanol is derived from plants, it has enhanced the 'Lifecycle Carbon Dioxide' performance. This for the reason that the plants being utilized as feedstock use carbon dioxide. Thus, burning the fuel produces carbon dioxide which is then balanced by carbon dioxide taken from the air.
Bioethanol is therefore, good for the environment because the carbon dioxide emissions are reduced. An order from the European Union was issued to support the development of biofuel. Provided that the amount of fuel in not above 5 percent by volume, then bioethanol can be combined with petrol. This makes it a convenient, clean, and environmentally sound alternative for fossil fuels.
The proposal of bioethanol as a replacement fuel is not just about cost reduction but how it can also help the environment. According to the University of Surrey, these ‘environmental gains’ are the following:
*Reduction in consumption of fossil fuels
*Greener emissions when burnt in comparison to petrol
*Greener process, less waste and harmful emissions during production
*Less pollution to water, air and land
*Production of useful by-products
*Biodegradable fuel
*Cleaner power generation from CHP replacing electricity from the grid.
Thus, bioethanol is advantageous for the environment.
