Organics Recycling Facility Feasibility Study
Organics Recycling Technologies
Aerobic Composting FacilitiesAdvantages
Greenhouse gas reduction
Simple operations
Beneficial reuse of materials
Stabilized material output
IssuesOdors
Feedstock composition requirements
Moisture control
Limited markets for compost
No renewable energy production
11
Conventional Anaerobic Digestion FacilitiesAdvantages
Greenhouse gas reduction
Renewable energy source
Accelerated processing period
Generates revenue
IssuesSignificant capital and operational costs
Complicated operations and pre-processing requirements
Inflexible to waste stream variations
Bacteria are fluid and temperature dependent
12
Organics Recycling Technologies
Organic Recycling Biomodule (ORB)
Combination of anaerobic & aerobic composting in innovative module:
Able to process wide variety of organics found in waste stream & sewage sludge
Recirculation of liquids
Geomembrane vessel
Biogas collection piping
Odor control
Stormwater management control
Low level of pre-processing

Organics Recycling Facility Site Layout
Biosolids Processing Advantages Renewable energy opportunities
Increases energy productionAssists in creating nutrient-rich compostAs solid waste it counts as recycling
17
Biosolids Recycling
Energy to power 380 homes annually
18
Organics Recycling Facility Renewable Energy Generation
Assumptions87 TPD25 year project life$36 per ton tipping fee (including administrative fee)$.07 per Kwh buyback15% total cost contingency
Total Capital Costs = $7 million
Net Project Revenues = $4.6 million Net Present Value
Return on Investment = 22%
Economics improve with inclusion of additional materials such as biosolids

Sustainable Solid Waste Program Partnering Opportunities
Complies with requirements of both State legislation & County Comprehensive PlanReduces solid waste system costsEnhances economic developmentPotential to create 100+ green jobsGenerates renewable, sustainable energyReduces greenhouse gasesCreates beneficial secondary uses for materials that would otherwise be landfilled
28
Benefits of a Sustainable Solid Waste Management Program
RecommendationReceive presentation from staffEndorse sustainable solid waste management program including materials recovery facility, organics recycling facility and flow control
Next StepsAt Dec. 14 BCC meeting, County staff will be requesting
specific authorization to begin design and permitting process for materials recovery facility and organics recycling facility
