Abstract: | Because landfill gas (LFG) contains an abundance of methane, the utilization of LFG as a renewable energy source is becoming
popular in many countries. LFG, however, contains various trace constituents, some of which may pose problems during utilization.
For example, siloxanes and halogenated volatile organic compounds (VOCs) can cause difficulties when present in the fuel of
gas engines. In addition, many VOCs and mercury have harmful effects on human health, especially on the health of workers
at landfill sites and people living near the landfills. Energy recovery from LFG is expected to make great progress in the
near future, particularly in Asia, but we found little information on the trace constituents of LFG in this region. Therefore,
we sought to characterize the trace components in LFG generated in two landfill sites in China and one site in Japan, to determine
the typical concentrations of these trace components in LFG, and to compare their concentrations among landfill sites in Asia.
We concluded that the trace components in LFG at the sites studied were mainly siloxanes generated from sewage sludge and
harmful benzene, toluene, ethylbenzene, and xylene compounds from petroleum products. |
