NOVELTY - Producing ethanol using corn plant material comprising cobs and corn, by providing an ethanol manufacturing facility with which the downstream location is physically associated and that is remote from the farms that supply the ethanol manufacturing facility with feed material, receiving corn plant material comprising cobs having undergone the upstream processing, subjecting to further processing at the downstream location, and employing the material that has undergone the upstream processing as a source of fuel for processing a corn plant ingredient into ethanol.    USE - The method is used for producing ethanol using corn plant material comprising cobs and corn (claimed).    ADVANTAGE - The method is cost-effective, and consumes less energy.    DETAILED DESCRIPTION - Method for producing ethanol using corn plant material comprising cobs and corn, involves (a) providing an ethanol manufacturing facility with which the downstream location is physically associated and that is remote from the farms that supply the ethanol manufacturing facility with feed material, receiving, at the downstream location, from several farm fields, corn plant material comprising cobs having undergone the upstream processing, subjecting the material that has undergone the upstream processing to further processing at the downstream location, and employing the material that has undergone the upstream processing as a source of fuel for processing a corn plant ingredient into ethanol at an ethanol manufacturing facility with which the downstream location is physically associated, there being no consumption, of the material that has undergone the upstream processing, to dry corn at the downstream location, (b) providing an ethanol manufacturing facility with which the downstream location is physically associated and that is remote from the farms that supply the ethanol manufacturing facility with feed material, receiving corn, from several farm fields, as feed material at the ethanol manufacturing facility, processing corn into ethanol at the ethanol manufacturing facility, and using, in the processing, heat for which there has been employed, as a source of fuel, corn plant material comprising cobs having been subjected to the upstream processing, there being no consumption, of the corn plant material comprising cobs that has been subjected to the upstream processing, to dry, at the downstream location, corn that is processed into ethanol produced by the method, the ethanol produced by the method being processed from corn undried by consumption, at the downstream location, of the corn plant material comprising cobs, or (c) providing an ethanol manufacturing facility with which the downstream location is physically associated and that is remote from the farms that supply the ethanol manufacturing facility with feed material, receiving corn, from several farm fields, as feed material at the ethanol manufacturing facility, processing corn into ethanol at the ethanol manufacturing facility, and employing the corn plant material comprising cobs, that has been subjected to the upstream processing, as a source of energy for use at the ethanol manufacturing facility at which the corn is processed into ethanol, there being no consumption, of the corn plant material comprising cobs that has been subjected to the upstream processing, to dry, at the downstream location, corn that is processed into ethanol produced by the method, the ethanol produced by the method being processed from corn undried by consumption, at the downstream location, of the corn plant material comprising cobs, where the corn plant material comprising cobs and corn are subjected to upstream processing that has been performed upstream of an ethanol manufacturing facility by employing harvesting equipment to pick, from several farm fields, corn plant material including ear corn comprising corn and cobs as components, and to return a corn plant ingredient other than corn to the farm fields, employing the harvesting equipment, that has picked the ear corn, to accumulate, at the farm fields, corn plant material comprising cobs, and delivering corn plant material comprising cobs, from several farm fields, to a downstream location that is (a) downstream of the farm fields, (b) remote from the farms where the cobs are harvested and (c) physically associated with an ethanol manufacturing facility that receives corn as a feed material.
