The Biorefinery in New York: Woody Biomass into Commercial Ethanol:  The Biorefinery in New York: Woody Biomass into Commercial Ethanol Cornelius B. Murphy, Jr. Tom Amidon SUNY College of Environmental Science and Forestry Syracuse, New York Outline::  Outline: Biorefining integrated with Bio-energy Biorefining integrated with Pulp and Paper Slide3:  The Wood-based Biorefinery:  The Wood-based Biorefinery Renewable, Sustainable Bioproducts: Fuels, Chemicals, Materials Renewable Resources to 'Green' Bio-Products Biomass Feedstock What::  What: Wood Growing, Procurement, Chipping, Chemical Processing – Forest Products Willow Biomass Growing, harvesting, Burning – Farmers/Wood Fuel Industry Fermentation of sugars to products and marketing – Ethanol Industry Slide6:  Slide7:  Where? Who?:  Where? Who? Conventional Wood Processing for Pulp/Energy in Ticonderoga, NY and Lyons Falls Biomass Willow – New York Field Trials in Tully, NY and Lyons Falls, NY Fermentation of Sugars in Oneonta or Fulton, NY When::  When: In the next year: Extraction of wood sugars at ESF Pilot Burning of extracted wood at Lyonsdale Ethanol from wood sugars at ESF Pilot Northeast Biofuels reconfiguration When::  When: Over the next three years Commercial scale extraction of wood sugars at Lyonsdale and shipping Extraction/burning - Lyonsdale/Oneonta Ethanol from Lyonsdale wood sugars produced at Oneonta/Northeast Biofuels Slide11:  Why – US Targets for a National Biobased Industry:  Why – US Targets for a National Biobased Industry NRC Report - 2000 Why – Paper Industry:  Why – Paper Industry Paper Industry – Cellulose for Paper and Lignin for Energy yields low profitability Insert a new process in front of the digester to extract hemicellulose and convert to ethanol, PHA’s etc. recover acetic acid and enhance energy efficiency Estimated Profit increase for complete Paper Industry application is $3.3 Billion/year (Thorp – PIMA ’04 Presentation) Total estimated at 1.9 Billon gallons ethanol and 600 Million gallons acetic acid for industry-wide application Why – Wood Burning Industry:  Why – Wood Burning Industry Wood burning industry – Marginal Economics and only lowest quality wood economic Evolutionary Change - Wood cost at $40-80 per dry ton ($0.02-0.04/dry pound) and extraction at 15% of mass recovered: 2/3 sugars 1/3 acetic acid/extractives Sugars at $0.07/pound and acetic acid/extractives at $0.30/pound Ave. $0.146/lb. value for the 300 pounds recovered from ½ to all of the wood cost Residue burned with cost reduction greater than the 20% of mass lost Biomass Willow an economic fuel crop Slide15:  Map showing concentration of existing ethanol facilities in the US Why–Wood Sugar Ethanol Production in Fulton, New York:  Why–Wood Sugar Ethanol Production in Fulton, New York New York Corn for Dairy Use – Most commodity corn shipped from Mid-West Corn Market Price fluctuation business risk Sugar source diversification beneficial short term/long term on business model Wood sugars locally grown and lower in cost Adjacent land with abundant low cost hardwood forests and good Biomass Willow growing potential 40% of New York corn production required to produce 150 MGPY of ethanol Slide17:  How:  How Fractionate Woody Biomass with a low cost and environmentally preferable system that preserves current uses Obtain a low cost, easy to clean up sugar stream Process advantageous for hardwoods Easy separation of valuable co-products How:  How Hardwoods are advantaged Use water as solvent Use Membrane/Filtration Technology Commercialize pentose fermentations Use conventional wood chips and preserve structure in process Biorefinery Core Competencies:  Biorefinery Core Competencies Feedstock Selection (Fast Growing and, perhaps Low or High Lignin/hemicellulose) Biodelignification (fungi, enzymes) Cellulose, hemicellulose, and lignin separation yielding 'usable' fractions (ESF Process/others) Cellulose, hemicellulose and lignin applications Waste and energy recovery Gasification for new products Slide21:  Conclusions:  Conclusions Wood holds great promise as the 'Biorefinery' feedstock of choice Cellulose, Hemicellulose, and Lignin will all enjoy broad utilization Advances in separations systems, biotechnology, biomass gasification, silviculture, and agro-forestry will establish the 21st century and beyond as the 'Age of Wood' We need to start with the low hanging fruit Slide23:  O2 Agenda 2020 Focus for the Future Meeting the Challenge of Deployment CO2 Breakthrough Mfg. Technologies Major Manufacturing Cost/Capital Reduction Significant Enhancement in Product Properties with Existing Assets Substantial Improvement in Energy Efficiency for Existing Processes Advancing the Wood Products Revolution  Improved Building Systems  Reduced System Costs Technologically Advanced Workforce From Workforce to Knowledge Workers in 7 years Positively Impacting the Environment Significant Reduction in Greenhouse Gases Decreased Ecological Footprint Future Industrial Connections:  Future Industrial Connections Paper Industry – Cellulose for paper and lignin for energy with hemicellulose and extractable such as acetic acid, turpentine, fatty acids, etc. for New Materials Wood burning industry – Lignin as fuel and all other components for new materials Purpose-built Biorefinery – All components available for new materials Technology appropriate may well differ depending on the industry Waste and energy recovery Gasification evolution has begun The Coming Age of WoodEgon Glesinger, 1949:  The Coming Age of Wood Egon Glesinger, 1949 …. forests can be made to produce fifty times their present volume of end products and still remain a permanently self-renewing source for raw materials…... Only forests - no other raw material resource - can yield such returns. The forest can, and so must, end the chronic scarcities of material goods that have harassed man’s experience since the beginning of history. Slide26:  Thank You
