2. Comparison of traditional rainforest soils (left) with biochar plot (right)

3. Agronomic Benefits of Biochar Increase soil organic matter Improve cation exchange capacity Increase microbial activity Improve nutrient efficiency Improve soil pH Increase yields

4. Environmental Benefits of Biochar Sequesters carbon

5. Biomass Pyrolysis to Reduce Atmospheric Carbon* Current situation – 4.9 gigaton increase per year Pyrolysis -- 4.0 gigaton increase per year 50% of Global Crop Residues 50% of Global Forestry Residues Pyrolysis – 3.1 gigaton increase per year 50% of Global Crop Residues, 67% of Forestry and Below Ground Biomass (stumpage) Forest Thinning * Review of the pyrolysis platform for coproducting bio-oil and biochar

6. Environmental Benefits of Biochar Sequesters carbon Reduce nitrous oxide emissions Reduces carbon emssions by reducing fertilizer and lime application. Reduce nutrient runoff Other

7. GHG Emissions from Corn Ethanol Corn Production Fertilizer and Lime15% Nitrous Oxide Emissions 25% Seed and Pesticides3% Fuel, LP Gas & Electricity 7% Biorefinery Natural Gas 34% Electricity 11% Grain Transport & Other 5% Total100%

8. Biochar Revenue from Crop Residue One ton of crop residue =.45 to.67 ton of CO 2 $20 per ton CO 2 = $9.00 to $13.40 per ton crop residue $50 per ton CO 2 = $22.50 to $33.50 per ton crop residue

9. Pyrolysis Produces Biochar and Bioenergy

10. Co-products of Biomass Pyrolysis Biochar (high energy density solid) Bio-oil (high energy density liquid) Synthesis Gas (syngas) ( low energy density gas)

11. Bio-Oil & Syngas Operate pyrolysis facility Co-fire electricity production Transportation fuel (gas and diesel) Renewable ammonia Other

18. Indirect Land Use Conversion Food versus Fuel versus Carbon Corn Ethanol -- (compete with each other) Biochar Pyrolysis -- (compliment each other)
