1 Building lifetime relationships with our clients and employees. Organic Waste Fuels Vehicle Fleet in Sacramento Omni Resort June

2 Convert Food Waste to energy (fuel) and fertilizer. Divert organics from landfill Produce Low Carbon CNG Vehicle Fuel Project Overview

3 Project Background South Area Transfer Station Sacramento, CA Unused site Sacramento County RFP Clean World and Atlas Disposal were awarded the project BioCNG selected for biogas to vehicle fuel upgrading Public-private partnership Clean World owns and operates the digester Atlas Disposal owns the CNG fueling station 3

4 SATS Site BeforeAfter

5 Feedstocks Source-separated organics Off-spec. packaged food 25 Tons per day- recently expanded to 100 TPD capacity

6 Pre-processing Technology DODA System Removes Contaminants Grinds and slurries wastes De-packages off-spec food.

7 Anaerobic Digestion Process

8 Anaerobic Phased Solids Separate hydrolysis and methane formation 3 tank system Thermophilic temperature High Solids ( 25%) Capability

10 Biogas to Vehicle Fuel

11 Biogas/Vehicle Fuel Benefits Significant savings over gasoline and diesel Lock in future fuel cost long term “Greenest” fuel resulting in a significant carbon footprint reduction Complies with CNG fuel specs and engine warranties 11

12 Biogas Treatment Requirements/Considerations Hydrogen Sulfide Removal Gas Compression Moisture Removal Siloxane/VOC Removal Carbon Dioxide Removal Fuel Requirements: Engine Manufacturers Specifications, SAE J1616

13 13 Skid-mounted BioCNG 100 Currently handling scfm Produces the equivalent of 330 to 400 gallons of diesel fuel per day* Phase 2 increases production up to 1,400 DGE *All biogas produced by the Clean World digester is currently being processed for vehicle fuel.

14 Package Engine Generator Operates in parallel with vehicle fuel production Includes gas conditioning A portion of waste gas from fuel production will go to the generator.

15 CNG Fueling Station 250 psig “buffer” storage 4,500 psig CNG storage Fast-fill dispensers

18 Miles Driven (x1000) CO 2 e Emissions (tons) Garbage Truck Municipal Sweeper Transit Buses Regional Freight Truck Bio-CNG v. Diesel Emission Reductions 10 garbage trucks converted from diesel to Bio-CNG – reduce 1,000+ tons CO2e annually

19 Federal Renewable Fuel Standard Credits Renewable Identification Numbers (RINs) Means to track, register and monetize environmental attributes of alternative vehicle fuels Available through 2022 Direct payment from producers– not a tax credit The Advanced Biofuel (D-5) RIN is currently trading at $0.52= $0.87/ DGE 19

20 California Low Carbon Fuel Standard CARB digester pathway= -15g/MJ carbon intensity Compared to diesel net carbon credit 110g/MJ $40/ton CO 2 =$ 4.64/decatherm (MMBtu) $0.60/ DGE

21 A Success Story A Productive Partnership Clean World Atlas Disposal BioCNG Advanced Technology A Growing Business Multiple Environmental Benefits
