An alternative way for the use of petrol to keep the environment pollution-free. 

The population is a grave concern in a country like India. The rise in population demands more resources in terms of food, shelter and energy. The energy requirement is met through various fuels produced from the non-renewable sources of energy, which is limited. The energy requirements from fuel are not only consuming our natural reserve of energy but also contributing to pollution. Usage of non-renewable sources of energy is affecting the living standards and endangering the environment. This necessity calls for an alternative source of energy.


Bioethanol - Bioethanol is the answer to this need.  The production of bioethanol is widely used for the generation of energy. Bioethanol is produced from waste generated from household and agriculture. Corn grain and sugarcane waste are commonly used for bioethanol production.

Bioethanol can be a replacement for petrol used in vehicles. Ethanol is made by the breaking down of the complex sugars in the corn grain and sugarcane into smaller molecules. The breaking down is performed by microorganisms in the absence of oxygen. This is termed as “anaerobic process”. 10% of this ethanol and 90% of petrol mixture is used as bioethanol. Countries like the U.S., U.K., Europe, China, etc. are already utilising this form of fuel.

Bioethanol may help to decrease the harmful emissions of gases from the vehicles. It can also reduce the CO2 levels in the environment. Greater acceptability and use of bioethanol will eventually bring a state of 'NO POLLUTION.'

Conclusion - As an individual, there are some ways you could stop the emission of harmful gases. One such way is the use of vehicles that use CNG as fuel. Secondly, reduce the use of private vehicles.
