  1. Pine Terpene Biofuels & Renewable Chemicals Jennifer Lauture, MSc Student Gary Peter, Professor School of Forest Resources & Conservation Alan Hodges, Extension Specialist, Food & Resource Economics

  2. Biofuels & Co-products 1st GENERATION BIOFUELS 2nd GENERATION BIOFUELS Extraction Deconstruction • Sugar • Ferment to EtOH • Sugar • Starch • Amylase + ferment to EtOH • Oil, animal feed • Oil • Transesterification to biodiesel • Glycerin • Lignocellulose • Sugar Platform • Size reduction + degradation + fermentation • Power, lignin • Gas Platform • Anaerobic digestion to biogas • Gasification + catalytic synthesis to liquid fuel • Power • Liquid Platform • Cracking / pyrolysis + upgrading Non-edible parts of food plants & undomesticated grasses & trees which have high heterogeneity & low chemical uniformity Come from domesticated plants breed & selected for concentration & yield of edible food molecules

  3. Southern Pines: The Renewable Chemicals, Biofuels & Bioenergy Star BIOLOGICALLY FEASIBLE SUSTAINABLE Growth exceeds removals High harvest index, energy positive, carbon negative due to low inputs Largest biomass supply chain in the world serves large markets for “traditional” lignocellulose products High value markets for mono- and diterpenes collected as co-products Pinene can be converted to JP-8 & JP-10 jet fuels Wood & wood pellets for electricity Lignocellulose biofuels from pine being commercialized? • Grows on land not suitable for food production • Year long carbon accumulation • Established growing systems based on robust empirical knowledge • Early stages of domestication • 3rd generation of breeding • Genetic engineering & clonal propagation methods developed • Naturally synthesizes & stores lipids & terpenes in wood • Inducible synthesis of terpenes in wood • Wood terpene content as high as 40% of wood dry weight

  4. Pine Terpenes Biosynthesis • Pines naturally synthesize a diversity of terpenes as defense compounds • Terpenes accumulate in naturally to >20% in heartwood • Constitutive synthesis • Inducible synthesis • Pinenedimers meet most specs for jet fuel Pine Chemicals is a $3 Billion/Y Global Business Pine Extraction Pulp mill Specialty Resins Live Tree Crude Products Gum Turpentine & Rosin CTO & CST Wood Turpentine& Rosin 850,000 Mg/y 450,000 Mg/y 5,000 Mg/y Final Products Specialty Chemicals Flavors & Fragrances Industrial Biofuels

  5. FDACS Office of Energy Award: Develop Cost Effective Tree Tapping Methods • Tree size & health with stimulators • Age • Stand treatment history • Thinning • Fertilization • Pinestraw raking • Fertilization • Inducers • Methyl jasmonate • Ethephon • MeJ + Ethephon • In-tree injection post tapping • Second year tapping of MeJ treated trees • Experimental design detects interactions between stand and tree features with inducers • Test ARA (Applied Research Associates) hydrotreating method • Target is < $800/ton J.
