Biomass EnergyBioenergy is nowadays being extremely popularized throughout the world due to its wide usage possibilities either in liquid, gas or solid state. The advantage of bioenergy is possibility of storing primary fuels, and its availability due to its adaptability to energy demands. Its advantage is also seen in lower level of greenhouse gases emission in comparison with fossil fuels since equal quantity of carbon dioxide required for its growth is released in the process of bioenergy combustion.

Biomass is an energy source obtained from the products of vegetal and animal origin (wooden mass, straw, saw dust, corn stalks, sunflower stalks, leaves, stable manure, communal and industrial waste). Biomass combustion is used for generating steam needed for providing heating in households and industry. In certain percentages biomass is also used in thermal power plants instead of fossil fules. Electric efficiency has been increased by 35% in biomass-fired power plants. Additional advantages include management and exploitation of waste as well as agricultural, household and wood industry residues.


Biogas EnergyBiogas is created by fermentation of agricultural, domestic and industrial waste. It consists of approximately 60% methane, 35% carbon dioxide and 5% mixture of hydrogen, nitrogen, ammonia, hydrogen sulphide, carbon dioxide, oxygen and water vapor. Taking into consideration the methane quantity it contains, biogas can be used as fuel as well. Its caloric value is proportional to methane quantity. Biogas is mostly used as combustion fuel in boilers or gas turbines for obtaining thermal and/or electric energy.


Liquid biofuelsThe use of liquid biofuels for transportation and for electricity production implies the use of biodiesel and bioethanol. Biodiesel is non toxic and biodegradable fuel. It is obtained from waste edible oil, oil rape, soya beans, sunflower and animal fat. Its quality is equal to light oil obtained in crude oil processing, so it is used as diesel engine fuel.
Bioethanol is mainly produced by fermentation of sugar-based raw materials, i.e., from sugar cane, sugar beet or grains. It is used as a fuel additive in petrol engines, as low mixture (up to 10% of bioethanol and 90% of petrol) which doesn't require engine adaptation. Only adapted engines can run on higher blends (up to 85% ethanol and 15% petrol) or even pure bioethanol.
