Introduction

• Biomass is the renewable energy sources. You can look at the representation of biomass in the CR.
• Biomass is a product of photosynthesis of plants, in which takes different forms. Energy use are useful dřevnatějící and fibrous tissue and packaging (wood, straw, leaves and pericarp).
• Emissions from biomass are considerably lower than from fossil fuels: biomass is known as "CO2 neutral" (burning of the released CO2 so much is consumed for further plant growth) in wood is sulfur in the straw she was 0.1% ( 2% for brown coal), nitrogen is only 0.1-0.5% (fossil up to 1.4%)
• The content of heavy metals in fuels from biomass is close to zero. Some energy crops may be used to deliberate accumulation of heavy metals from contaminated soils and burning of heavy metals can be separated from flue gas.
• The energy contained in biomass (13-18 MJ / kg - by the water content) is comparable to Severočeské brown coal.
• Biomass can be used either by type for burning or to biochemically transform (fermentation, esterification) to more refined bio-fuels such as biogas, biodiesel or ethanol.
• Currently the best attainable in our so-called residual biomass, which are crop residue in agricultural and forestry wood waste whose quantity is estimated at 8 to 10 thousand tons / year.
• Another source of biomass plantations as energy crops (poplar, willow, příp.rostliny), which can be set up on unused agricultural land or on land devastated by human activities (landfills, dumps, contaminated soil).
• Harvested or residual biomass burning is regulated at different types of biofuels: chips, pellets, briquettes, bales.
• Ash from the incineration of biomass use as fertilizer.
• Production and biomass creates new jobs and strengthen the local economy - the money expended for fossil fuels goes outside the village and in the case of biomass remain in the community or region.
• Plantations of perennial crops and trees at suitable locations may play a positive role in protecting against water and wind erosion. These areas can also become a factor contributing to the ecological stability of landscape.
