Fairview Swiss Cheese

• Anaerobic Digester Project

2
Project overview

• A feasibility study conducted by Penn State for
  Mercer County investigating the potential of a
  community digester to process manure and food
  waste into renewable energy.
• The study was funded by a PADEP solid waste
  planning grant.
• Fairview Swiss Cheese whey and Joy Cone batter
  waste are processed in an anaerobic digester
• The digester uses Mobilized Film Technology (MFT)
  to convert up to 95 of COD into biogas in 8
  hours.
• The effluent is processed in a waste water
  treatment plant, removing solids and discharging
  clean water
• The biogas will be used in an engine generator
  set (275 Kw) with heat recovery to process milk
• The projects estimated cost is 2.2 million with
  873,000 of the cost secured from State and
  Federal renewable energy grants.

• Offsets 65,000 gallon fuel oil purchases
• Generates up to 2,000,000 kWh electricity
• Reduced GGE by replacing fossil fuels with
  renewable energy
• Reduced whey and batter waste disposal costs
  50,000 annually

Annual Gas Usage
Usages are annual but not for the same time
periods
12
Potential Heating Fuel Cost Savings (MASH/MMS,
VoTech, MARC)

• Biomass boiler efficiency 80 (equal to present
  gas boiler system)
• Assume replacing 80 of current gas usage with
  biomass boiler
• Projected annual heating fuel savings
• Wood chips - 184,000
• Switch grass - 156,400

District Heating Systems using CHP
CHP Combined Heat and Power Uses Steam turbine
to Generate Electricity
14
Producing Electricityfrom Renewable fuels(PUC
Net Metering Ruling)

• Allows for net metering of electricity from
  renewable fuels
• Net metering allows trading Kwh produced for Kwh
  used
• Electricity produced enters the Grid

15
Annual Electric Usage
Usages are annual but not for same time periods.
16
Potential Electricity Generation and Savings
(MASH/MMS, VoTech, MARC)

• 200 Kw Generator
• Operating 240 days
• Projected annual Electricity Production
• 1.2 million Kwh
• Electricity savings 102,000
• based on 0.085 per Kwh
