NOVELTY - System (200) comprises: a pyrolysis unit (201); at least two feeds in communication with the pyrolysis unit, where at least two feeds comprises a biomass feed, and at least one of a waste plastic feed and a Fischer-Tropsch wax feed; a separation unit (203) for separating the pyrolysis oil into at least two pyrolyzed component fractions according to their boiling range; a hydrotreating unit (207) for hydrotreating the pyrolyzed component fractions so as to yield one or more hydrotreated fractions; and an isomerization unit (209) for catalytically-isomerizing the hydrotreated fractions.    USE - The system is useful for producing isomerized product, preferably biofuels (claimed) for energy production. The system is useful for producing transportation fuels from waste plastic and biomass.    ADVANTAGE - The system is feed-tolerant (which allows for variability) and provides an economy of scale, while typically retaining the environmental benefits associated with such processing of such feeds.    DETAILED DESCRIPTION - System (200) comprises: a pyrolysis unit (201); at least two feeds in communication with the pyrolysis unit, where at least two feeds comprises a biomass feed, and at least one of a waste plastic feed and a Fischer-Tropsch wax feed, the feeds can be channeled into the pyrolysis unit sequentially or simultaneously so as to produce pyrolysis oil, and each feed can be varied so as to modulate the properties of the pyrolysis oil so produced; a separation unit (203) for separating the pyrolysis oil into at least two pyrolyzed component fractions according to their boiling range; a hydrotreating unit (207) for hydrotreating the pyrolyzed component fractions so as to yield one or more hydrotreated fractions; and an isomerization unit (209) for catalytically-isomerizing at least one of the hydrotreated fractions so as to yield at least one isomerized product.    DESCRIPTION OF DRAWING(S) - The figure shows a schematic representation of a system for producing fuel products from a multiplicity of feeds.
