1. A Sustainable Biosolids Process & Fertilizer Product Dana G Taylor and Jeffrey C Burnham, Ph.D. Long-term effective biosolids solution High-value slow-release fertilizer Green sustainable business

2. The Biosolids Solution – Sustainability 61 MM ton U.S. Fertilizer Market Need 7.5 MM ton U.S. Biosolids Production AM Process Enhanced Efficiency Fertilizer Class A+/EQ Granulation Processing Slow-release N Nearly odorless Crop effective Competitive Ag economics Growing Population Requiring Increased Crop Production Increasingly Limited Disposal Options

3. Key Aspects of Business Model Do not transport biosolids cake very far Utilize a safe Class AA biosolids treatment Construct modular plants Emphasize redundancy Manufacture a valuable marketable product Be community positive Key Approaches

4. Create Value With Biosolids Recover value from biosolids Nitrogen Micronutrients Organics Amino acids Manufacture saleable enhanced-efficiency fertilizer Increased crop production value Create GREEN value: Reduction in GHG emissions for biosolids treatment and fertilizer manufacture

5. Biosolids Containing Enhanced Efficiency Fertilizer HIGH ‐ NUTRIENT SLOW ‐ RELEASE FERTILIZER 16 ‐ 0 ‐ 2 ‐ 17 ‐ 3 ‐ 16 (N ‐ P ‐ K ‐ S ‐ Fe ‐ Org) Characteristics: Spherical granules; 260/120/80 SGN 6-8 # hardness Dry - >98% solids no biosolids odor Application rates: pounds per acre - not tons 5

6. 6 The Ammonium Mix (“AM”) Technology Conversion of biosolids to high nitrogen granular fertilizer – Reacts concentrated acid and anhydrous ammonia with biosolids for a two step heat drying process – Couples nutrients to biosolids organic molecules to create a slow-release fertilizer Key is long reaction times under heat and pressure. Incorporation of high plant nutrient value Use of nutrient chemicals that positively reduce odorants
