 | |  Cargill North Carolina Landfill Gas Energy Project
| Location | Fayetteville, North Carolina | | End User(s) | Cargill, Inc. | | Sector(s) | Food products | | Landfill(s) | Cumberland County Landfill | | Landfill Size | 1.65 million tons waste-in-place (2000) | | Project Type | Boiler and Direct Thermal (process heater) | | Project Size | 500 standard cubic feet per minute (scfm) | | Environmental Benefits | Carbon sequestered annually by 1,400 acres of pine or fir forests, annual greenhouse gas emissions from 1,100 passenger vehicles, or carbon dioxide emissions from 14,600 barrels of oil consumed. Annual energy savings equate to heating 1,600 homes. Estimated emissions reductions of 0.0017 million metric tons of carbon equivalents. | | LMOP Partners Involved | DTE Biomass Energy, Enerdyne Power Systems |
What do soybeans and garbage have in common? Both represent a viable source of biomass energy and both are critical components of Cargill’s operations in Fayetteville, North Carolina. Cargill turns soybeans into oilseed. Next door, at the Cumberland County Landfill, tiny microbes turn garbage into landfill gas (LFG), an economical substitute for natural gas.
Cargill burns LFG to meet its thermal needs while extracting oilseed from soybeans. Oilseed is used in hundreds of food products, plus it can be used in industrial applications such as biodiesel fuel, building materials, plastics, adhesives, candles, crayons, and paint.
The project’s highlights include:
- Steam boiler and process heater consume a combined 30 million Btu per hour.
- LFG displaces about 20 percent of Cargill’s annual fossil fuel purchases.
- Gas collection system includes 62 vertical gas wells and two centrifugal blowers.
- 2-mile pipeline dips 85 feet under the Cape Fear River.
Before the LFG reaches Cargill, it is compressed and dewatered in a system designed, constructed, and operated by Enerdyne Power Systems (EPS), LMOP's 1999 Industry Partner of the Year, and DTE Biomass Energy. EPS is a LFG system developer, co-developer, owner, and operator who has forged partnerships with both the public and private sectors and has used their skills as developers to find innovative solutions to project problems.
