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
