David Penoyer, P.E. Senior Project Engineer. SCS EngineersTampa, Florida. Landfill gas (LFG) is a by-product of the decomposition of municipal solid waste in the anaerobic environment of a landfill.LFG is approximately 50% methane (CH4), 49% carbon dioxide (CO2), and <1% non-methane organic compo

1. T h e S t a t e ofL a n d f i l l G a s E n e r g yi n t h e U n i t e d S t a t e s Definition of “Renewable” - should LFGE be included?
Not here to debate this
However, as long as we put waste in the ground we will have LFG
Until we change our philosophy, let’s use itDefinition of “Renewable” - should LFGE be included?

4. Why does EPA care about LFG?
Methane is a potent global warming gas
Landfills are the largest human-made source of methane in the U.S.
Many cost effective options for reducing emissions
Most common is flaring
5. Why does EPA care about LFG? 1 MW generated by LFG equals:
Taking ~ 6,100 cars off the road for a year
Planting 8,300 acres of trees
93,000 barrels of oil each year
Reduces local air pollution
Creates jobs and improves economic development near landfills
12. Trend toward more direct-use projects
165,000 scfm
21 operational in 1990...100 operational in 2001 Technology Summary
Growth in Direct Use Projects
Greater Diversity in Project Types
Selection of technology is site specific
Technologies exist for low and high volumes of LFG production
Many proven/cost effective ways to utilize LFG
Niche technologies are gaining popularity, but are slow to emergeTechnology Summary

13. Currently, most projects generate electricity
Reciprocating engines
Gas turbines
15. Microturbines & LFG Units range from 30 kW to 100kW
Can operate at low LFG flows (50 scfm)
35-50% CH4
Low NOx, CO emissions (only 10% as much as IC engines)
16. Direct-use projects are growing
Direct thermal / Medium Btu
Boiler
High Btu
Leachate evaporation
Greenhouse
Vehicle fuel
Artists Studios
Aquaponics/Hydroponics
20. Fuel cell projects
PV on landfills “brightfields”
Wind turbines on landfills
Bioreactor landfills
New techniques for enhanced LFG recovery
21. Valuable energy source
400-600 Btu/cf
Reduce major heat-trapping gas - methane
Improved local air quality
Odor control
Sustainability
Avoided fossil energy emissions
22. Emission trading/offset opportunities
Federal RPS
DOE’s 1605(b) program
Possible new LFG tax credit - both Section 29 & 45
Utility restructuring
Green power/green pricing programs
23. A recognized renewable resource
Among the most cost-competitive
Green pricing opportunities
At least 90 utilities have developed or plan to develop GP programs
Customers are willing to pay premium prices for green power
