1. A method of on-farm processing a biomass feedstock into useful industrial chemicals, comprising:
- (a) placing a non-sterilized biomass feedstock at a density of approximately 11 lb/ft3 to 21 lb/ft3 or maintained in bales on a false floor within a single sealed vessel with an overhead delivery system and delignifiying said biomass feedstock by adding a transition metal and a peroxide to produce a delignified biomass;
(b) subjecting said delignified biomass from (a) to a solid-substrate reaction to produce cellulase, said solid-substrate reaction comprising inoculating the delignified biomass through the overhead delivery system with a thermophilic anaerobic microorganism and maintaining a first temperature range of 50-65°
C. within the single sealed vessel to produce a delignified biomass with attached cellulase and to produce fermentation residues;
(c) subjecting said delignified biomass with attached cellulase from (b) to a simultaneous cellulolytic and solventogenic solid-substrate reaction by inoculating the delignified biomass with attached cellulase of (b) with an anaerobic microorganism through the overhead delivery system and maintaining the single sealed vessel at a second temperature range of between 25-40°
C. under anaerobic conditions to produce industrial chemicals and fermentation residues; and
(d) percolating a media from the overhead delivery system through the biomass to remove fermentation residues and industrial chemicals during (b) and (c) and collecting said percolated media from beneath the false floor and separating industrial chemicals from said media and recycling the media back to the overhead delivery system.

Abstract
A method for on-farm processing a biomass feedstock into a useful industrial chemicals includes the steps of (a) delignifying the biomass feedstock to produce a delignified biomass, (b) subjecting the delignified biomass to cellulase production, (c) subjecting the delignified biomass with attached cellulase to simultaneous cellulolytic and solventogenic reactions to produce useful industrial chemicals (d) collecting and separating the useful industrial chemical from the fermentation broth and (e) collecting the fermentation residues.
