Growing Biomass is a rural, labor-intensive activity, and can, therefore, create jobs in rural areas and help stem rural to urban migration. Biomass is carbon based and can be composed of different mixtures of organic materials such as, Hydrogen, oxygen, nitrogen, and also small quantities of other atoms, which are mainly metals. For plants, carbon used from biomass is absorbed from the atmosphere as carbon dioxide using energy collected from the sun, during their process of photosynthesis. Plants may be eaten by animals and is then converted into animal biomass. If plant material is not eaten it is generally either broken down by some microorganisms, or burned, such as fossil fuels (coal, oil, and gas), which comes from biologic material.
In its narrow meaning, it's an equivalent word to biofuel that is fuel derived from biological sources. The broader sense of bioenergy consist of biomass, the biological material used as a biofuel, as well as scientific, economic, social, and technical fields related to using biological sources for energy. Types of biofuels Solid biofuels: Solid biofuels include manure, wood or charcoal burned as fuel as well as more recent innovations like high-density clean burning pellets. Solid biomass can be burned to produce electricity or heat either as part of a co-firing power plant or by itself. The most important advantages of biomass fuel is that it is most of the time got by waste-product of other processes, product or residue, such as farming, animal husbandry and forestry.
Biomass can be burned directly or biogas can be burned as the fuels or converted to the liquid bio fuels. Examples of the biomass and their uses for the energy- 1. Agricultural crops and the waste materials- burned as the fuel or were converted to the liquid bio fuels. 2. Wood and the wood processing waste- burned to the heat buildings, to produce the process heat in the industry, and to generate the electricity.
Alternative sources of fuel can be obtained from a variety of energy sources, including those derived from biomass, various liquid fuels, and even energy from the sun (The New Book). Researchers from the Department of Energy, or DOE for short, are searching for alternative sources of fuel. Many of the solutions involve the use of Biomass (The New Book). Biomass is created when plants, garbage, or any other natural waste is chemically changed through a process called fermentation (The New Book). During the fermentation process, bacteria are used to convert the natural waste into various gases and liquid fuels (The New Book).
Biofuels have the possibility to produce energy while decreasing overall CO2 emissions. In this paper, I will examine the basics of biofuels, their potential benefits, their history and recent developments, and the scientific, and ethical considerations that arise when talking about their use. Biofuels are “any type of liquid or gaseous fuel that can be produced from biomass substrates and that can be used as a (partial) substitute for fossil fuels” (Giampietro, Ulgiati, & Pimentel, 1997). Examples include ethanol, methanol, and biodiesel (Giampietro, 1997). There are many methods to extract biofuels from biomass.
It is a renewable and nourish able source of energy used to create bio gas or other forms of power. Some sources of bio mass are as: Agricultural residues: remains from agriculture, crops, and harvesting or processing of them. Food waste, from kitchen, restaurants, hotels preparation and processing, and post-consumer waste. Wastes from industry and co-products from manufacturing and industrial processes. Manure from cattle’s, pets, poultry house.
Ring structures incorporate two additional functional groups: the hemiacetal and acetal. A major part of the carbon cycle occurs as carbon dioxide is converted to carbohydrates through photosynthesis. Carbohydrates are utilized by animals and humans in metabolism to produce energy and other compounds. Carbohydrates are initially synthesized in plants form a complex series of reactions involving photosynthesis. They store energy in the form of starch or glycogen in animals and humans.
Biomass is a lignocellulosic material derived from living or recently living organic materials such as wood and agricultural residues. In a board vision, non-lignocellulosic materials like animal and municipal solid waste (MSWs) are also as termed biomass (Kambo & Dutta, 2014). There are many potential feedstock’s that may be utilized from a range of plant matter waste to agricultural waste. There are differences in the compositions of the biomass and there are many advantages to using biomass as an energy source. Poultry litter is heterogeneous material that consists of both lignocellulosic and non-lignocellulosic materials.
Photosynthesis is a biochemical process in which plant, algae, and some bacteria harness the energy of light to produce food. Nearly all living things depend on energy produced from photosynthesis for their nourishment, making it vital to life on Earth. It is also responsible for producing the oxygen that makes up a large portion of the Earth¡¦s atmosphere. Factors that affect photosynthesis are light intensity and wave length, carbon dioxide concentration, and temperature. Plants are autotrophs that mean they are able to synthesize food directly from inorganic compounds, instead of relying on other organisms.
Processes required converting source materials to fuels To understand biofuels, the first step is to understand what biofuels are. The definition of a biofuel is: any fuel whose energy is obtained through a process of biological carbon fixation. So, obviously, to produce biofuels, biological carbon fixation is an important procedure that is required. Biological carbon fixation is a process conducted by living organisms that convert inorganic carbon, mostly carbon dioxides, into organic compounds that can be used as fuel for living organisms. For example, photosynthesis is a process that happens in all kinds of living organisms that have chloroplasts.
