NOVELTY - The method for using biomass with which a plant serves as main component for the biomass production, where the plant is igniscum-hybrid CPVO 2007/0149 belongs to the family of Polygonaceae, comprises cultivating the plant on an agrarian surface, cutting the plant in the vegetation phase as damp harvesting above the root bundle, supplying the harvested plant with a residual moisture (20%) immediately to a fermentation process in a bioreactor and then removing after the biogas fermentation. The harvested plant is supplied immediately to a burning process.    USE - Method for using biomass with which a plant serves as main component for the biomass production, where the plant is igniscum-hybrid CPVO 2007/0149 belongs to the family of Polygonaceae (claimed).    ADVANTAGE - The method ensures effective usage of higher biomass with higher energy values that delivers high calorific- and high biomass final products.    DETAILED DESCRIPTION - The method for using biomass with which a plant serves as main component for the biomass production, where the plant is igniscum-hybrid CPVO 2007/0149 belongs to the family of Polygonaceae, comprises cultivating the plant on an agrarian surface, cutting the plant in the vegetation phase as damp harvesting above the root bundle, supplying the harvested plant with a residual moisture (20%) immediately to a fermentation process in a bioreactor and then removing after the biogas fermentation. The harvested plant is supplied immediately to a burning process. The harvested plant and/or the biomass are alcoholically fermented, in which grape residues from the wine and wine spirit preparing are supplied. The harvested plant and/or biomass are supplied to biological waste from food and/or battle wastes and are pyrolised and pelletized so that charcoal develops. The harvested plant and/or the biomass is milled in a dust fine manner, and then injected over a nozzle into a reactor, and is mixed with sludge and then burned. The supply of fuel and atmospheric oxygen is carried out in temperature-dependent manner so that the burn process is temperature-constantly regulated in the incinerator. After harvesting, the harvested crop in a compactifying unit carried along with a harvesting machine is pressed or compactified, and then supplied to compactified harvested crop after the harvest process either directly the incinerator or a storage silo. INDEPENDENT CLAIMS are included for:    (1) a harvest mechanism; and    (2) incinerator for biomass.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic collocation of wet procedure and dry harvest procedure (Drawing includes non-English language text).
