Improvement of Water Quality in Howrah District of West Bengal by using Bio-fuel

This paper examines that transportation generates maximum pollution in Howrah district mainly in urban area. Development & urbanization has led this city population increased very rapidly in the recent past. Howrah has a well connectivity of multimode road network which is very benefiting the population but use of conventional fossil fuel slowly ruining the Biodiversity and National Wealth like Water. Vehicular emissions from transport sector are main sources of chemical hazard, which releases toxic gases to the atmosphere, like NOx, SO2 & CO, mixes with air & condense with water, evaporates to form cloud and then reaches the ground in the form of acid rain, which contaminates the fresh water sources & damages the water bodies/resources at large. This can be reduced by using of bio fuel in mixture 10% with the petroleum products. Bio fuel is a renewable fuel & does not have any harmful chemical that damages the environment. It is bio degradable in nature can be harvested in waste land or semi-arid land. It has high flash point & cost is less than petroleum products [1]. The Govt. of India & the Govt. of West Bengal has already announced different levy on bio fuel production in Howrah district & many cooperative societies also taken up the matter seriously at district level. Transportation sector emits pollution higher than any other sector, according to data around 73% in India 2005 [13] & it is forecasting that between 2020 the transport sector is going to have 21% increase in emission [12]. The major concern for west Bengal is that the transport emission mainly SPM10 & NO2 in industrial belt especially in Howrah district [14]. Howrah district was regarded as Manchester of West Bengal, because of its industrial growth in pre Independence era. Improper planning, and unlawful design has choked the district especially urban life, the city is famous for its multimode transport facilities.
