TECHNOLOGY FOCUS - CHEMICAL ENGINEERING - Preferred Method: Milling comprises subjecting the dried biomass feedstock material to a first hammer milling step to reduce the size to less than 5/16 inches in diameter, subjecting the product to a second hammer milling step, and screening to recover a classified product of - 80 mesh. Attrition milling of the classified product is carried out to obtain an air classified product having an upper size limit of less than 140 to 200 mesh size. The dried starting material with a size within the range of + 30 to - 6 mesh is pelletized prior to the hammer milling. Drying is carried out using heat resulting from combustion of the explosible powder in an oxidizing gas. An additive is added to the biomass feedstock material.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Component: The additive comprises boron, calcium, phosphorus, magnesium, silicon, sulfur, aluminum, iron, titanium, tantalum, zirconium, and/or zinc. It comprises titanium dioxide, coal, ultra clean coal, metal, sulfur dust, or phosphorus dust.    TECHNOLOGY FOCUS - METALLURGY - Preferred Component: The additive comprises bronze.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The biomass feedstock material comprises crops, wastes and residues, starch crops, grains, rice, barley, rye, oats, soybean, maize, wheat, sugar cane, sugar, cocoa bean, sugar crops, con, grasses, industrial hemp, Giant reed, cotton, seeds, husks, seaweed, water hyacinth, algae, microalgae, herbaceous and woody energy crops, wood chips, bamboo, wood, stem wood, cellulose, lignin, hardwoods, American sycamore, black locust, eucalyptus, hybrid poplar, hybrid willow, silver maple, softwoods, cedar, pine, Monterey pine, invasive types of brush, fishmeal, fat, whey, agricultural wastes, rice straw, chaff, wheat straw, sugar cane bagasse, corn stover, con stalks, biochar, forestal wastes, sawdust, shavings, lumber wastes, pulp and pulp waste, mill wastes, thinned woods, brush, municipal and industrial solid wastes, construction wastes, demolition wood wastes, urban wood wastes, yard wastes, agricultural residues, livestock wastes, dry manure solids, poultry wastes, intermediate enzymatic and acid hydrolysis bio-solid byproducts, waste solids from biological processes of ethanol fermentation, and methane production, or anaerobic digested corn stalks.    TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The additive comprises plastic, polyester dust, a hydrocarbon-bearing solid, polypropylene, polystyrene, acrylonitrile butadiene styrene, polyethylene terephthalate, polyester, polyamides, polyurethanes, polycarbonate, polyvinylidene chloride, polyethylene, polymethyl methacrylate, polytetrafluoroethylene, polyetheretherketone, polyetherimide, phenolics, urea-formaldehyde, melamine formaldehyde, or polylactic acid.
