Abstract:
The demand for all forms of energy is growing rapidly, which is influenced by global economic growth and population growth. The use of fossil fuels, whose reserves are otherwise limited, leads to environmental pollution and climate change. The solution to the problem is achieved by increasing energy efficiency and using renewable energy sources. Biomass, as a renewable source of energy, means matter made of plant mass in the form of products, by-products, waste or residues of that plant mass in agriculture, forestry and associated industry, as well as the biodegradable part of industrial and municipal waste. Biomass is a clean fuel, without harmful and dangerous substances in it and is carbon neutral (it is part of a closed carbon cycle). Carbon from the atmosphere accumulates in newly grown plants, during the burning of biomass, carbon is released into the atmosphere again as carbon dioxide. While respecting the principle of renewable development (plant as many trees as are cut down), this energy source has no significant impact on the environment. By processing biomass, we can obtain different types of biofuels that represent an ecological alternative to the still dominant fossil fuels. With the combined production of heat and electricity in cogeneration plants, the utilization rate of biomass increases drastically - it reaches more than 85%. Biomass can be called a sustainable source of energy because its supplies are quickly renewed, its use is harmless to the environment with reduced emissions of gases with the greenhouse effect.
