Question

Write a short note on biofuels.....!!!

Answer 1

Biofuel is a fuel that is produced through contemporary biological processes, such as agriculture and anaerobic digestion, rather than a fuel produced by geological processes such as those involved in the formation of fossil fuels, such as coal and petroleum, from prehistoric biological matter. Biofuels can be derived directly from plants, or indirectly from agricultural, commercial, domestic, and/or industrial wastes.Renewable biofuels generally involve contemporary carbon fixation, such as those that occur in plants or microalgae through the process of photosynthesis. Other renewable biofuels are made through the use or conversion of biomass (referring to recently living organisms, most often referring to plants or plant-derived materials). This biomass can be converted to convenient energy-containing substances in three different ways: thermal conversion, chemical conversion, and biochemical conversion. This biomass conversion can result in fuel in solid, liquid, or gas form. This new biomass can also be used directly for biofuels.

Answer 2

Biofuel

Explanation:

Biofuel is an energy source that is derived from renewable plant and animal materials. Biofuels play a valuable role in reducing carbon dioxide emissions. Biofuels is one of the largest sources of renewable energy that is used today and it is made from organic matter or wastes. Currently, it is used in transport sector, it is blended with existing fuels like petrol or diesel.

Examples of biofuels are ethanol (made from corn or sugarcane), biodiesel (made from vegetable oils and animal fats), green diesel (made from algae and other plants), and biogas (methane made from animal manure and other waste).
