TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Process: Preparation of biofuel e.g. ethanol produced from a renewable plant based feedstock (M3) involves(A) providing plant based feedstock containing starch material(25 wt.%);(B) milling plant based feedstock to an effective size to produce powdered meal, converting powdered meal into the mash by adding effective amount of water to powdered meal, which mash has a gel-like consistency;(C) cooking mash for effective cooking time at effective cooking temperature;(D) hydrolyzing cooked mash with use of a hydrolyzing agent for an effective amount of hydrolysis time and at an effective hydrolysis temperature and in the presence of a shock wave at least twice the speed of sound thereby liquefying a portion of the cooked mash;(E) adding effective amount of yeast to the hydrolyzed cooked mash and subjecting it to fermentation, thereby producing ethanol, carbon dioxide and stillage;(F) distilling at least a component of the fermented hydrolyzed mash and separately collecting the ethanol, the carbon dioxide and stillage; and(G) digesting the stillage anaerobically in a reactor vessel to produce biogas and solid waste.In the process (M1), the first biomass feedstock is high starch content material; the second biomass feed stock comprises fraction of sugar. The ratio of first to second biomass feedstock is 2:1- 6:1. Either first biomass feedstock or second biomass feedstock is a cellulosic material rich in five and six carbon organic molecules. The third biomass feedstock is cellulosic material rich in five and six carbon organic molecules is combined with first and the second biomass feedstock. The reduction of the first biomass feed stock is accomplished by modified wet milling. The mash contains a quantity of solid constituents that are disassociated to such an extent that any starch (97%) in the mash can by converted to sugar within a period of less than or equal to 45 minutes. The shock wave is created by steam injection at least three injection sites in series and is delivered during liquefaction of starches and during hydrolysis. The quantity of stillage from fermentation is exposed to a second microorganism in heated, plug flow anaerobic biological reactor creating methane. In the process (M3), the enzyme is alpha amylase and is added in at least one of step of c; d or e. The shock wave is generated by the injection of steam. The feedstock is biomass comprises a mixture of starch based materials, sugar based materials and cellulosic based materials, provided that biomass feedstock (25 wt.%) be comprised of a starch based material. The second shock wave of at least twice the speed of sound is provided in step h, during anaerobic digestion of the wet solid residue material. The fermentation is a continuous fermentation, and the reaction vessel in which anaerobic digestion occurs is operated as a plug flow reactor with back mixing. Preferred Component: The biomass sugar based material is selected from sugar beets, sugar cane, and molasses.    TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The biomass starch based material is selected from corn, barley and wheat. The biomass cellulosic based material is selected from straw, wood, paper waste, corn stover and switchgrass. EXAMPLE - No suitable example is given.
