1、The natural gas produced in the landfill is called landfill gas.

2、Migration rule of landfill gas arising from non-sanitary municipal solid waste landfill

3、Biogas include marsh gas, landfill gas, digester gas. They distinguish by the producing location.

4、The collection and reuse of landfill gas put an end to the risk of explosion.

5、Extraction method of landfill gas was introduced based on practice experience.

6、A mathematical model of landfill gas migration was established under presumption of the effect of gas slippage.

7、The world's largest landfill gas plant sits atop the Puente Hills landfill—the largest in the U.S.—which accepts trash from Los Angeles County.

8、Leachate and landfill gas (LFG) are released continually in the process of landfill stabilization, which causes a series of resources and environment problems.

9、Sanitary landfill is a filling method that can control percolating and filtrating liquid and landfill gas, and universally adopted by developed countries.

10、Some use waste heat from industrial processes, others use fuels that would otherwise be wasted, such as landfill gas.

11、Based on the typical MSW composition in Shanghai, lab-scale simulated landfill columns were used to study the effects of different leachate recirculation operations on landfill gas (LFG) production.

12、Closure cover system is one of important parts of landfill site construction, it includes landfill gas discharge guiding layer, geotechnical film, drainage layer and plant cover surface soil layer.

13、The objective of the project activity is to provide electricity to the local power grid through the collection and recovery of landfill gas for power generation.

14、This paper gives the mathematical model of landfill gas based on the fuzzy seepage theory, and get the analytic result by use of fuzzy structuring element.

15、Some problems should be solved in construction of landfill gas electricity plant were pointed out, an appeal to government for supporting the project construction was made out.

16、Instead of letting this gas escape and pollute the air, some waste management companies are employing a capture and purification system that allows them to convert the landfill gas (LFG) into energy.

17、It provides basis for designing landfill gas control system and evaluation of environment, finds a new way for study of underground seepage problem such as mine gas and oil contamination.

18、In many countries power from landfill gas or waste-to-energy plants (like the one at Spittelau, outside Vienna, illustrated above) attracts subsidies of one kind or another because it saves emissions.
