TRCPA - Just thinking out loud...Malaysia produces 10 million MT of EFB waste per year; QL purchased Boilermech, which produces a biomass boiler and sells into several countries; QL was on track to complete their EFB to pellet production facility and presumably is up and running. With this as a backdrop and the statements found in QL's quarterly reports, I would have to agree with you they appear to be on track to need several multiples of KDS installed to support their plans.
QL has reported that EFB pellets produce 80% of the energy of coal. The selling point of course is that EFB pellets are a renewable energy source. Combined with the other information above, QL would seem to be targeting the replacement of coal fired power plants with EFB pellet fired plants.
This would seem to underscore your thoughts about where the next sales will or have come from. Time will tell, but I still believe there are other projects that may come to fruition sooner or in parallel with QL. Information about Brazil became very scarce and I wouldn't rule out something from SA.
fwiw,
