Biomass energy pros and cons in a nutshell | Renewable Green Energy Power. Biomass energy is a renewable energy source derived from biological materials that are called biomass. As with all renewable energy sources biomass energy has its pros and cons. Biomass Fuels The most common sources of biomass are wood, waste of biological form (i.e. sawdust), animal manure, landfill gasses, biofuel crops (i.e corn) and garbage (Municipal Solid Waste). It should be noted that in the case of garbage and the waste to energy processes (i.e. burning municipal solid waste for the production of heat and/or electricity) it can only be considered renewable if the fuel used is purely of biological origin and does not contain any non-organic materials otherwise it cannot be considered sustainable.
In effect biomass energy results from sun. The circle of biomass (see picture 1) starts from plants that use sun’s energy in their photosynthesis process that makes them grow and thus store energy into their leaves and roots. Picture 1 Biomass Energy Pros Renewable energy. About the Author. Advantages and Disadvantages of Biomass. Speaking of resources, the world changes pace everyday. First there was evolution which took us from wood to steel to iron (and more), then development happened and took us to the stage that we are in now.
Now we see that there are distinct shifts in policies which have taken us back to our roots and have been able to reacquaint us with the natural resources that we once used. One of those resources was biomass. This article will try to give you an in-depth review on the advantages and disadvantages of biomass energy. What is Biomass Biomass is biological matter that is acquired from plants and animals and has large amounts of carbon as well as traces of oxygen, nitrogen, hydrogen, alkaline earth and heavy metals in it. The main sources that are used to formulate biomass are wood, alcohol fuels and solid waste. Advantages of Biomass Uses Renewable Resources: Biomass is derived from sources like plants and animals, in short, sources which are replaceable. Disadvantages of Biomass.
How Biomass Energy Works. Biomass is a combination of organic and biological materials usually composed of both plants and animals. It is composed of stored energy derived from the sun, and can release a new source of energy when physical and chemical processes are applied to it. Most biomasses materials come from wood, trees, grasses, agricultural crops, garbage and other urban wastes. Human and animal wastes are sources for biomass energy too. • The most well known source of biomass energy is by burning of wood. This produces heat, light, electricity and steam which are also forms of energy to be used for household and industrial purposes. • There is another simple way of how biomass energy works. . • Agricultural crops like corn and sugarcane undergo the fermentation process to produce fuel like ethanol, which is used for trucks, cars and other means of transport. • Vegetable oils and animal fats can be converted to produce biodiesel which is also used in vehicles and other kinds of transportation.
Biofuel. A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms. Examples of this carbon fixation occur in plants and microalgae. These fuels are made by a biomass conversion (biomass refers 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. Bioethanol is an alcohol made by fermentation, mostly from carbohydrates produced in sugar or starch crops such as corn, sugarcane, or sweet sorghum. Biodiesel can be used as a fuel for vehicles in its pure form, but it is usually used as a diesel additive to reduce levels of particulates, carbon monoxide, and hydrocarbons from diesel-powered vehicles.
