  1. Catawba CountyRegional EcoComplex andResource Recovery FacilityUsing Existing Landfill Gas Project to Produce Additional Renewable Energy Jeff Ramsdell, Ph.D., P.E. Appalachian State University Barry B. Edwards, P.E. Director of Utilities and Engineering Catawba County

  2. The EcoComplex – Catawba County, NC

  3. Catawba County EcoComplex & Resource Recovery Facility Ecological-industrial park Synergetic waste and resource management, renewable energy production, and local economic development Public Private Partnerships 805 acres around Blackburn Landfill 452 tons/day of municipal and 88 tons of construction waste daily. 3MW grid-tied LFGTE - GE-Jenbacher engines.

  4. 1990 NC Waste Reduction Mandate • 1990 baseline 1.51 tons/capita • 10% by 2000 (1.36 tons/capita) • 15% by 2005 (1.28 tons/capita) • 20% by 2010 (1.21 tons/capita) • 25% by 2015 (1.13 tons/capita) • 34% by 2020 (1 ton/capita)

  5. FY 2008-09 at 1.10 tons/capita

  6. STRATEGY: INDUSTRIAL ECOLOGY

  7. Site Plan

  8. Landfill Gas to Energy

  9. Average output: 2.3MW + 8.1 MMBtus Waste Heat

  10. Blackburn Landfill, Catawba County, NC • Facility began producing electricity in November 1999 • Facility has operations at a 94% up-time • To date, facility has produced 168,000 MW electrical • + Electrical Sales of $5,698,595 • +$257,258.00 in REPI • +$279,041.00 in REC • Facility has provided electricity to approximately 600 average homes annually

  11. Current and Future Uses of Waste Heat from Electricity Production • Biodiesel Research & Production Facility • Algae Growth and Research for Mitigating CO2 • Biosolids Management Facility • Solid Waste Digester

  12. Private Industrial Partners Gregory Wood Products Pallet One

  13. Wood Waste Gasification 1.9MW, + 6.7MM Btus Heat

  14. Multi-Feed Anaerobic Digester Ag & Food Wastes Algae Animal Manures Mixed Paper Wastewater sludge

  15. Oilseed Feedstock Crops & Processing

  16. Oilseed Feedstock Crops Double crop potential of rapeseed/sunflower in NC: 3.5-5 tons/acre = 220 gal oil/acre/year. (7.7-11.2 tons/Ha/yr = 2,000 Liters Oil/Ha/yr)

  17. EcoComplex Feedstock Processing Station Capacity: 100,000 gal oil/year (~400,000 liters oil/year) Crop area (with double cropping): 450 Ac (180 Ha) Material handling: 1900 tons seed/year, 1300 tons of meal

  18. Cellulosic Ethanol/ Algae Alternative Cap

  19. Algae for Mitigating CO2 Gen-Set Heat employment: • Injecting CO2 into Algae ponds to facilitate growth • Blending Algae with oilseed meal to enhance livestock feed • Algae used as soil amendment in Greenhouse • Possible gasification in Bio-Energy Facility

  20. BIOMASS ENERGY POTENTIAL
