[Terrapreta] ? GHG emissions from Biomass Combustion ?

[Peter Read]

Hi 
provided it is fully combusted there should be no CH4 or CO
how much CO2 depends on the particular biomass but a good rule of thumb is 50% C by weight in dry biomass
So 1 tonne Biomass contains ~500Kg C yielding 500*44/12 Kg CO2 = ~1800Kg CO2

  Hi All, 

  Could anyone provide the figures Tony Lovell is asking for below;



  "Erich

  Thanks you for sharing our work with your colleagues at TP. 

  Would you or any of your colleagues be able to assist me with finding some information?

  I am looking for general parameters on how much of what GHG’s are produced due to the combustion of biomass. In particular if we were to combust say 1,000kgs dry matter of switchgrass or similar material how much CO2, CH4, CO, etc etc would be released. 

  Any assistance you can provide is greatly appreciated.

  Take care,

  Tony Lovell
