Biomass refers to renewable organic material derived from plants and animals, used as a fuel source. To obtain bio-energy from biomass, it can be directly burned for heat, converted into electricity, or processed into biofuels like ethanol and biodiesel.
Here’s a more detailed explanation:
What is Biomass?
Biomass is a renewable resource, meaning it can be replenished naturally.
It includes a wide variety of organic materials, such as wood, agricultural residues (like straw), food waste, and even animal manure.
Biomass is considered a sustainable energy source because it can be regrown in a relatively short time, unlike fossil fuels.
Obtaining Bio-energy from Biomass
There are several ways to harness the energy stored in biomass:
Direct Combustion:
Biomass can be burned directly to generate heat, which can be used for heating, electricity generation, or industrial processes.
Conversion to Electricity:
Heat generated from burning biomass can be used to boil water, producing steam that drives turbines to generate electricity.
Conversion to Biofuels:
Biomass can be processed through various methods, such as fermentation or anaerobic digestion, to produce biofuels like ethanol and biodiesel.
Anaerobic Digestion:
In this process, microorganisms decompose organic matter in the absence of oxygen, producing biogas, primarily methane, which can be used as a fuel.
Gasification: This process converts biomass into a gas fuel, which can be burned to produce heat or electricity.
