8. 8 INFILCO DEGREMONT, INC 8 Zero Waste policy to reduce greenhouse gas emission Organic waste contains high carbon energy Anaerobic digestion of High-solids organic becoming increasingly popular New business opportunities BACKGROUND Organic waste – a clean & renewable Energy source

9. 9 INFILCO DEGREMONT, INC 9 WHAT IS HiSAD  High Solids Anaerobic Digestion – Patented Technology  Low CAPEX/OPEX process  20 % or greater organic wastes  Excellent candidate for co-digestion

10. 10 INFILCO DEGREMONT, INC 10 HiSAD is a combination of solids digester and anaerobic filter HiSAD…

11. 11 INFILCO DEGREMONT, INC 11 HiSAD… HiSAD system combines benefits of unmixed high solid digester and anaerobic porous media filter >70% VSR achievable Solid digester can be operated at 37 o C for 12 days or 55 o C for 7 days Phase separator collects and recirculates liquid digestate continuously through anaerobic filter Process Description:

12. 12 INFILCO DEGREMONT, INC 12 HiSAD… Process Advantages/Strengths: Achieves >70% volatile solids reduction (VSR) without mixing in both stages Produces greater volume of biogas and high quality biosolids (Class A permit pending) and final liquid effluent Greatly reduces final biosolids disposal volume Energy saving technology Wide range of application - organic wastes including animal manure, organics in solids waste, food waste, etc System resilient to highly variable feed waste Short SRT, small footprint Most operation can be automated, eliminating need for professional wastewater plant operator
