Non-food plant biomass is subjected to hot-water extraction in a pressurized vessel at an elevated temperature up to about 250° C. and at a pH below about 7.0, to yield an aqueous extract containing hemicellulosic components, other wood-derived compounds, and a lignocellulosic residue. The separated aqueous extract or liquor is purified and concentrated through a multi-step process producing fermentable sugars. At each stage, inhibitory chemicals such as acetic acid, lignin, and furfural are separated and eventually recovered as commercial chemicals. The lignocellulosic residue may be further processed, as a material with enhanced resistance to sorption of water, for manufacture of improved pulp and paper, construction materials, pellet fuel, and / or other useful products.

The invention provides a method and apparatus for recovering food losses from the main recovery system, the handsorters, and the color sorters. A recovery shaker conveyor located beneath the main recovery system to catch food and vines which are tossed off the end of the main recovery system. The food and vines are turned over during the fall, thus loosening some food from the vine. The loosened food falls through the openings in the recovery shaker conveyor onto a recovery cross conveyor which is situated in between the chains of the recovery shaker conveyor and under the handsorters. Food which is rejected by the color sorters also falls onto the recovery cross conveyor and is directed toward a dirt sorter electronic system. The food which is rejected by the handsorters, is placed on a recovery sorter conveyor which is fed into the recovery cross conveyor for re-examination. The dirt, debris, and unsuitable food fall off the recovery cross conveyor through the dirt sorter electronic system to a trash chute and then to the ground. The remaining suitable food is then guided along a recovery feed conveyor which drops the remaining suitable food onto the discharge conveyor, where the suitable food is elevated and discharged into a receiving truck.
