New Perspec*ve -“Lowest Cost” Energy From
Vast Biomass 36, Landfill Gas 2
• -->> cont; •3 MAINLY WASTE:
✔ 3i Landfill Gas(LFG):
• Fair por(on of gas is let off as flaring(burning) even there is LFG management
system in place(Hofste2er BV, GC Environmental, Comcor Environmental +),
Some small old landfill sites can also recover energy (Deponigas ApS+), Much
higher u(liza(on % at large landfills, Power genera(on needs proper gas
filtering of siloxane, H2S etc(Unison SoluDons, Xebec, PpTek, SulfaCHAR,
Prodeval +), recovery around 30-35% range with large majority Reciproca(ng
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 commercializa(on(Renovare Fuels, Velocys+)
• Note: Current waste disposal on land fill is close to none in Germany,
Netherlands, Sweden etc, more 3-5 na(ons with 5% range: those na(ons are
not focused on LFG recovery as future energy source.
