Fiberight Company

Fiberight? is a privately held company founded in 2007 with current operations in Virginia, Maryland and Iowa. As a clean technology company, Fiberight focuses on transforming post-recycled municipal solid waste? and other organic feedstocks? into next-generation renewable biofuels?, with cellulosic ethanol as its core product.

Some coproducts from Fiberight processes also include C5 sugar? based acids as well as other fiber content items such as SMA road fibers?, animal absorbents and fire retardant panel board. Their pilot plant facilities have been on-going during 2008-2009. In November 2009, Fiberight purchased a former dry-mill corn ethanol plant in Blairstown, IA.

Technology

Fiberight has developed a Targeted Fuel Extraction? (TFE?) process to cost effectively convert MSW? into cellulosic biofuel, plant energy and marketable electricity with maximal conversion efficiency focused on individual elements of the waste stream. Fiberight’s TFE process recognizes that sold waste is neither homogeneous? nor fully convertible to energy. Fiberight developed a system that bifurcates? organic and inorganic wastes and converts them according to type. TFE process separates, cleans and processes organic and hydrocarbon fractions then converts the organic fraction into cellulosic biofuel, the hydrocarbon fraction into plant energy and electricity, and the inert fraction into recyclables or beneficial products. Fiberight achieved high yield conversion factors at its Lawrenceville, VA pilot plant due to the robust enzyme catalysts? used in strategic partnership with three different enzyme suppliers.

Fiberight Key Process

• Pre-sort and primary pulping removes unsuitable waste materials to optimize process
• Separates organic from inorganic components for efficient conversion to biofuel and credit qualification
• Creates clean high BTU plastics stream for process energy – system requires minimal external energy inputs
• Wash stage for quality fractionation & ash removal
• Continuous fed batch – high solids loading for cellulosic sugar concentration
• Dirty vs. clean stage for water treatment
• Cellular disruption for yield maximization combined with sterilization stage
• Sterility management in enzymatic digestion & fermentation
• Secondary wash to overcome glucose inhibition & glucose losses
• Enzyme recovery enables high enzyme dosing and yield improvement while controlling cost
• Glucose concentration step improves ethanol yield & energy balance while obviating "stuck" fermentations
• By products for beneficial sale or energy production – plastic fraction ideal for energy
