Advantages And Disadvantages Of Biomass

However, despite its many advantages biomass still has many disadvantages. Firstly it is not as efficient as fossil fuels, for example the ethanol produced for cars via biomass is not even close to the efficiency of petrol and does damage to engines over time. It also has the potential to harm the environment through increase of methane gases which are produced as a bi-product if animal and human waste is used. Biomass also requires a large distance away from residential areas in order to burn it and a large amount of fuel in comparison to other energy sources which can have dramatic effects if large portions of forests are cut down to provide lumber.1

Biomass energy is a renewable energy source from living or recently living plant and animal materials which can be used as fuel. There are many ways in which we could produce this energy such as heat and steam. Also, instead of leaving waste in landfills, we’re reusing that waste and converting it into usable power. Pros: 1. Renewable. 2. Dependency on Fossil Fuels is Reduced 3. Protects air quality 4. Improves forest health. Cons: 1. Not 100% clean. 2. Requires a lot of water. 3. Not as efficient as fossil fuels.

acre of trees can. Hemp can also be used as a biomass fuel, as it is

Biomass is the entire mass of organisms in a certain area or section, which can be used as fuel to convert to electricity. When plants absorb energy from the sun and carbon dioxide from the air, the chlorophyll in the plants transform this raw energy into food, which is called photosynthesis. The process of photosynthesis gives the plant the needed energy to live, which is passed to the next consumer of energy. Because the energy used to keep every organism on Earth alive comes from the sun, when the organic matter is burned it releases the stored energy from the sun, which can be transformed into electrical energy. Although burning biomass to obtain the heat energy used to receive the needed electrical energy releases carbon dioxide, the energy source is available anywhere, unlike wind, hydroelectric, ocean, geothermal, and solar energy, which makes it available to anyone and cuts back on expenses to transport the energy.

Nowadays, biofuels have become essential for future economic development and environmental protection. Primarily, their environment-friendliness and low carbon emissions are emphasized as the main advantages. However, in reality, few investigations were made to find out the disadvantages of such renewable alternative, and it may bring much more negative impacts than its advantages.

A biofuels is a fuel that is produced through biological processes, such as agriculture rather than a fuel produced by geological processes. Hence a biofuel is a fuel which is gained from the living matter. A biofuel is a hydrocarbon that is made from a living organism hence we humans end up using this to power something. In a short amount of time, if a hydrogen fuel is produced from organic matter hence this is known as a biofuel being produced. Biodiesel is an fuel which is similar to fossil diesel. Therefore biofuel is any fuel from which energy is gained through a process of biological carbon fixation. Biodiesel can be produced from vegetable oil, animal oil/fats and waste cooking oils. A well known process used to convert these oils

Biofuels is a nickname to renewable fuels from biological source that can replace fuels that come from fossil fuels like gasoline and diesel. Unlike fossil fuels, biofuels can be easily produced from raw agricultural materials. These facts ensure that the reservoir of fuel will never

The Biomass energy is an organic matter that is used by photosynthesis. This is used to generate energy and the most common energy is coming from the wood of the trees, corn, municipal solid waste, and sugarcane. The biomass is used to create ethanol, biodiesel, bio oil and biogas. This in turns create electricity with steam turbines and gasifies to produce heat. The advantage of using the biomass over the fossil fuel is that biomass is a renewable carbon source, zero net carbon dioxide emissions, lower methane, sulfate, and hydrocarbon emissions, and the most important is no dependence on foreign oil. Another is the geothermal energy, in which it uses the heat from the earth to warm things up. The common source is cost effective, reliable, and environmentally friendly. The main sources of uses are to heat homes, greenhouse, industrial process heating mineral recovery, fisheries and also mitigate global warnings. Geothermal energy is more valuable than the fossil fuels because it is an inexhaustible energy source, lot less emissions in the atmosphere, more efficient than solar energy, work under any kinds of weather conditions. The fossil fuels are irreplaceable, create massive environmental pollution and are also causes the major factor of the global warming and the ozone layer depletion. Also the Biomass and the Geothermal are very inexpensive compare to the fossil fuels by almost 50 percent.

Through anaerobic digestion, methane gas is produced, which can then be refined for use as fuel. Biomass can also be converted into ethanol or biodiesel, which can serve as substitutes for currently used transportation fuels, decreasing the reliance on fossil fuel. Crops such as sugar cane or corn can be fermented to produce ethanol, while natural oils from palms or soybeans can be used to create biodiesel. Another way to harness the energy of biomass it to burn it. Even though the combustion of solid biomass may not be as environmentally sound as fermenting and refining it to make fuel, combusted biomass still emits less pollution than the combustion of other fuels such as oil and coal. The combustion of biomass can be used domestically to heat homes in place of oil or gas heaters, or even industrially to provide electricity to run machinery. With less of a negative impact on the environment, the use of biomass to create energy can decrease the world's reliance on fossil fuels, and decrease pollution through the conversion of waste into a usable energy source.

Biofuel is a fuel that is made up of dead biological matter. This is how a biofuel is distinguished from a fossil fuel." In order to be considered as a biofuel, the fuel must contain over 80% renewable materials"(1). The organic matter (biomass) that makes up biofuel can be gotten from corn, soybeans or various other photosynthetic plants. The specific type of biofuel produced from grains is Ethanol, the other one who produced from mostly oil and fat is Biodiesel. Biomass is organic instruments made by plants and animals. It is contains stored energy from the sun. At the bottom of the food chain, plants merge with solar radiation through photosynthesis. They then change it into chemical energy in the form of glucose, or sugar.

The production of fuel from photosynthetic organisms like plants and algae is a renewable process using solar energy; therefore, biofuel is a capable resource and biomass is obtained for its production is from harvesting forestry and other plant residues. Even garbage from domestic houses and food industries can also be used as starting material of oil production by thermochemical liquefaction.

The disadvantages of Biomass Energy are that affect the evaluation of biomass as a viable solution to our energy problem: the effects of the farming and production of biomass and the effects of the factory conversion of biomass into usable energy or electricity. There are as many environmental and economic benefits as there are detriments to each issue, which presents a difficult challenge in evaluating the potential success of biomass as an alternative fuel. For instance, the replacement of coal by biomass could result in "a considerable reduction in net carbon dioxide emissions that contribute to the greenhouse effect. We are all aware of the problems

Nation’s socio-economic development leads to increased use of energy which cannot be fulfilled using renewable energy sources. Biomass energy is generated

Direct combustion is the most common way of converting biomass to energy - both heat and electricity- and worldwide it already provides over 90% of the energy generated from biomass. Direct combustion of solid biomass fuel is well understood, relatively straightforward, commercially available, and can be regarded as a proven technology. Biomass combustion systems can be easily integrated with existing infrastructure. Direct combustion of biomass for heat generation is widely used in cold climate regions where there are significant annual demands for space heating and hot water. Domestic biomass -fired heating appliance in the developed countries have been improved with automation and standardized fuel supplies (e.g. wood pellets). Compared with traditionally open fireplaces, these advanced domestic biomass applications not only achieve efficiencies of over 70% but also with greatly reduced atmospheric emissions (Liu H. 20 II)

Biogas is biofuel and it generally refers to the gas produced from organic matter as it is broken down by biological means. It can be produced by anaerobic digestion or fermentation of biodegradable materials. It primarily comprises of methane, carbon dioxide, nitrogen, hydrogen and small traces of volatile compounds.
