plant diagram photosynthesis
CO2 from the atmosphere and water from the country are linked in the process of photosynthesis to produce carbohydrates, which are the building blocks of biomass. Solar energy, which drives photosynthesis is stored in chemical bonds of the structural components of biomass. If we burn biomass efficiently oxygen from the atmosphere combines with carbon in plants to produce CO2 and water. The process is cyclic, because carbon dioxide is then available for the production of new biomass. Typical sources biomass is? Lesa? Waste from industrial processing of wood? Agricultural waste? Urban wood waste? Waste water treatment & landfill? Other natural resources (straw, peat, bagasse, etc.) Unlike other energy sources, the use of biomass for energy is often to dispose of waste biomass, which would otherwise create a risk to the environment. Today, there are ranges of biomass utilization technologies that produce useful energy from biomass. • Direct combustion Gasification • • • Anaerobic digestion Methanol & ethanol production There are many problems that hinder the development of energy from biomass. In this regard, the formulation of sustainable energy policies and strategies to address these problems is really pre-condition for development and promotion of energy from biomass. Speed and residual fossil fuels releases CO2 into the atmosphere caused international concern and led to intense efforts to develop alternative, renewable sources, primary energy sources. Biomass, solar energy stored in chemical form in plant and animal materials are the most valuable and promising alternative fuels not only electricity, but also for other industrial and domestic applications on the ground. Provides not only food but also energy, building materials, paper, textiles, medicines and chemicals. Biomass is used for energy purposes, since man discovered fire. It is important to say that biomass absorbs the same amount of CO2 in the cultivation the report when burned as fuel in any form. This means that the biomass contribution to global warming, is zero. Moreover, biomass fuels contain negligible amounts of sulfur and their contribution to acid rain, is minimal. After millions of years, natural processes in land transformation of organic matter in today's fossil fuels: oil, natural gas and coal. In contrast, biomass fuels derived from organic matter in trees, agricultural crops and other living plant materials. CO2 from the atmosphere and water from the country are linked in the process of photosynthesis to produce carbohydrates, which are the building blocks of biomass. Solar energy, governed by photosynthesis is stored in chemical bonds of the structural components of biomass. If we burn biomass efficiently, oxygen from the atmosphere combines with carbon in plants produces no CO2 and water. This process is cyclical, because carbon dioxide is then available for production new biomass. Typical biomass resources include: • forest residues from logging and other forest wood waste • Waste sawdust from woodworking industry, cut-off, bark, etc. • agricultural waste residues, palm oil, rice husks, sugar cane, coconut shells, husks for coffee and cocoa, cotton & corn residues, etc. • Organic waste manure, waste, food processing. • urban waste wood, wooden pallets, packing material, etc. • Waste & landfill municipal wastewater, landfill gas, etc. • Other natural resources straw, peat, bagasse Fossil fuels not renewable. Oil, natural gas and coal we use today are gone forever. However, biomass fuels are renewable resources, the growth of new plants and trees replenishment supply. Unlike other energy sources, the use of biomass for energy is often a way to dispose of biomass waste materials that would otherwise create an environmental risk. In this document these technologies, the use of biomass to produce useful energy from biomass in comparison: • Direct Combustion • gasification • anaerobic digestion • Methanol & ethanol production to better illustrate the following chart (Figure 1) shows the consumption energy from biomass in selected Asian countries. Figure 1 Consumption of biomass in selected Asian countries. There are many problems hampers the development of energy from biomass. In this regard, the formulation of sustainable energy policies and strategies to address these problems is really pre-condition for development and promotion of energy from biomass. About the Author:
