Introduction:
Biotechnology is a modern branch of ‘Biological Sciences’
utilized integrated principles of Biology and Engineering,
to enhance the industrial production and researches for human welfare like; production of bio-fuels to save the earth by reducing emission of green house
gases. Bio-fuels are alternative fuels made from plants and plant-derived
resources used mainly for the transportation means by two types; bio-ethanol
and biodiesel. Bio-ethanol, used as substitute for petrol for road transport
vehicles, is mainly produced by the sugar fermentation process of cellulose
which is mostly derived from maize and sugarcane. Biodiesel on the other hand
is mainly produced from oil crops such as rapeseed, palm, and soybean which
have received much attention in recent years. The vast majority of energy is
currently derived from fossils fuels, limited non-renewable and polluting
resources. First generation bio-fuels are produced by fermenting plant-derived
sugars to ethanol, while, second generation bio-fuels will also focus on using
residual non-food parts of current crops as well as other crops that are not
used for food purposes, such as switch grass, cereals that bear little grain
and more fibers, wood chips, etc.
Competent micro-organisms can be developed by ‘Genetic
Engineering and Cell Culture Principles’ to make
efficient ‘Microbial Culture’ of Algal, fungal, Bacterial resources
populations for effective enzymatic catalysis to breakdown the hemi-cellulose into
sugars, which can be fermented further for the production of bio-fuels,
efficiently to meet the current requirement. The
advances of Biotechnological tools may unravel the problems of poor
production rate and better policies can be formulated to save our environment
form the increasing level of hydrocarbons,
greenhouse gases, smokes etc. produced from the burning of conventional
energy sources like coal, petrol, diesel and wood charcoal. The level of air and water pollutants also can be reduced
by using cellulosic wastes for the production of green energy to run our
transportation like; CNG on the minimum rate of pollutants in respect to
conventional fuels which produces more pollutants in the atmosphere. To stop
ever-increasing petroleum products consumption and emissions in transport
sector, alternatives of CNG and bio-fuels can help a lot to reduce air
pollutants to save us. Bio-fuels can replace 30% of current transportation
energy, which will reach up to 50% by 2025, with much of the increase in demand
from developing countries. Many countries are setting up new initiatives for
the production and use of bio-fuels for transportation. India has enhanced
their bio-fuels production upto 20% which was only 5% earlier and it will
continue further for sustainable environment by increase biomass yield
per hectare, reducing greenhouse
emissions etc.
Production Strategies:
Biofuels are
produced from the Bio-mass basically through enzymatic catalysis of for
producing bio-gases, biofuels like as bio-diesel, ethanol, etc.
- The solid biological substances like as wood or
Sugar cane waste can be burnt in to power generators for producing heat directly
to run turbines and electricity production as well.
- The oilseed crops such as Jatropha curcas found
enriched in oil (27 – 40%) and how it will be used (e.g., to fuel cars or power
generators). Jatropha oil has been used in India for several decades as
biodiesel for the diesel fuel. This tropical crop has great potential for fulfilment the forthcoming requirements of
Disel, especially in India.

3. Microbial basically Bacterial breakdown, of
manure via anaerobic catalysis for producing Methane gas as green energy
resources.

Applications of Biofuels Technology:
Biofuels
are primarily used as renewable replacements for fossil fuels in
transportation, water warming, electricity generation, lightening and cooking purposes
with very lower-carbon alternative and minimizing the waste and pollutants being
made from biological organic matters like plants, agricultural waste, and algae
etc. Such biofuels are known as clean and afe energy resources for saving our
earth and forthcoming generations as well. They also reduce the pollutants,
greenhouse gases, and can be used in existing engines through blending some proportion
of ethanol like as, E10 gasoline widely known as biodiesel blends.
Transportation Fuel: The biggest application, substituting for
gasoline (bioethanol) and diesel (biodiesel) in various vehicles, including
heavy-duty transport and aviation.
Heating: Used as a replacement for heating oil in
homes and industrial settings.
Electricity & Power: Can be burned for thermal
energy or used in power plants for captive power generation.
Bioproducts: Converted
into other valuable products like hydrogen or used for cleaning oil spills.
Cooking: Biogas can serve as a cooking fuel,
especially in off-grid areas
Cleans
Oil Spills and Grease: Biofuel is known to be
environmental-friendly. It can also help clean up oil spills and grease. It has
been tested to work as a potential cleaning agent for areas where crude oil had
contaminated the waters.
