Targeted Fuel Extraction Process

Fiberight developed a Targeted Fuel Extraction (TFE) process to cost effectively and efficiently convert municipal solid waste (MSW) into cellulosic biofuel, plant energy and marketable electricity.  Fiberight recognized early on that sold waste is neither homogeneous nor fully convertible to energy in its raw state.  The TFE is an remarkably innovative system that separates, cleans and processes organic and hydrocarbon fractions of the waste stream.  Once separated, the organic fraction is converted into renewable fuels, including cellulosic biofuel, the hydrocarbon fraction into plant energy and electricity, and the recyclable fraction is sold to as recycled content feedstock to manufactures and generates an additional revenue stream.

Innovative technologies, proven on a commercial scale, such as enzyme recycling and cellulosic sugar concentration have been developed to achieve high yield renewable fuels at a low conversion cost.  During 2009, Fiberight demonstrated the value of robust enzyme catalysts used by our strategic technical partner, Novozymes.  Fiberight is now able to forecast, with extensive data to back-up us up, its ability to produce cellulosic ethanol on a commercial scale.

We understand the different compositions of materials contained in the nation’s MSW and we’ve perfected our ability to convert these materials into renewable fuels, without generating dangerous emissions or effluents.  This is what differentiates Fiberight’s technology from other less efficient thermal or chemical waste to energy projects. Most importantly, the technology platform has been tested at an industrial scale, all the way through finished transportation grade fuel; making Fiberight one of the first companies in the US to achieve this important milestone.

TFE – An Optimized Processes

  • MSW, used as feedstock for production, generates revenue, as opposed to being an expense.  A tip fee, competitive to landfill tip fees, is charged to accept MSW from the solid waste generator / hauler.  The solid waste hauler deposits MSW on the tipping floor.
  • In a continuous fed fashion:
    • First sort removes unsuitable waste, such as inert materials and large bulky items
    • Second sort separates the curbside-type recyclables from food waste and other organics in the waste stream
      • Additional revenue generated from marketable recyclables recovered:
        • Cardboard & Paper
        • Plastic (ideal for energy production)
        • Metal
        • Wood
        • Textiles
  • The organics go through a primary wash for ash removal and cellular disruption for yield maximization combined with a sterilization stage
    • High solids loading for cellulosic sugar concentration and efficient conversion to renewable fuels and credit qualification
    • Glucose concentration step improves fuel yield & energy balance while obviating “stuck” fermentation
  • Enzymatic digestion & fermentation
    • Secondary wash to overcome glucose inhibition & glucose losses
    • Enzyme recovery enables high enzyme dosing and yield improvement while controlling cost
  • Closed-loop waste water treatment
  • Once renewable fuel production is complete a digestate fiber is available for compost production or can be pelletized for energy recovery
