[Terrapreta] ? GHG emissions from Biomass Combustion ?

[Tony Lovell]

Peter

Thanks for such a prompt response - which of course leads to more
questions!!

What happens to the other 50% of material in the biomass that is not C? And
if the combustion happened in a less than complete manner, eg in a bushfire
or burn to clear land, what would the mix of GHG's be like?

Tony

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
