NOVELTY - The method comprises collecting biomass at collection points, which are connected with a biomass refining plant (10) by a conduit loop, introducing the biomass into the conduit loop to form a slurry (46) of biomass and liquid, transporting the slurry of biomass and liquid through the conduit loop to the refining plant, where the biomass is subjected to cooking, removing water from the slurry and continuously reusing the water to transport additional biomass, and pretreating the slurry of biomass and water in a network to a pH favorable for later disintegration of lignin and cellulose bonds.    USE - The method is useful for collecting and refining lignocellulosic biomass.    ADVANTAGE - The method is capable of simply, effectively, rapidly and economically large scale collecting and refining the lignocellulosic biomass with reduced energy consumption.    DETAILED DESCRIPTION - The method comprises collecting biomass at collection points, which are connected with a biomass refining plant (10) by a conduit loop, introducing the biomass into the conduit loop to form a slurry (46) of biomass and liquid, transporting the slurry of biomass and liquid through the conduit loop to the refining plant, where the biomass is subjected to cooking, removing water from the slurry and continuously reusing the water to transport an additional biomass, pretreating the slurry of biomass and water in a network to a pH favorable for a later disintegration of lignin and cellulose bonds at the refining plant, joining streams of slurry transported from the collection points into a single slurry stream directed to the refining plant and splitting the water removed from the slurry coming from the refining plant for recirculation, and removing water to maintain a relatively constant amount of water circulating in the system. The slurry is pH-adjusted for introduction into the cooking phase. The conduit loops are connected the collection points to the refining plant. Each of the loops is operated independently, and is matched to the refining plant production capability.
