New Perspective -“Lowest Cost” Energy From
Vast Biomass 36, Landfill Gas 2
• -->> cont; •3 MAINLY WASTE:
3i Landfill Gas(LFG):
• Fair portion of gas is let off as flaring(burning) even there is LFG management
system in place(Hofstetter BV, GC Environmental, Comcor Environmental +),
Some small old landfill sites can also recover energy (Deponigas ApS+), Much
higher utilization % at large landfills, Power generation needs proper gas
filtering of siloxane, H2S etc(Unison Solutions, Xebec, PpTek, SulfaCHAR,
Prodeval +), recovery around 30-35% range with large majority Reciprocating
Engine special flexible power generator(Siloxa AG, GE Jenbacher - Clarke-
Energy+),
• 1MW+ capacity(can produce more than 1MW per hr) type system can use Gas
Turbine, a few add CHP for higher recovery, or profitable Landfill gas to liquid
fuel is a pilot+ level commercialization(Renovare Fuels, Velocys+)
• Note: Current waste disposal on land fill is close to none in Germany,
Netherlands, Sweden etc, more 3-5 nations with 5% range: those nations are
not focused on LFG recovery as future energy source.
