The key objective of this research is to validate the methodology for measurement of off-gassing from storage of wood pellets as well as development of data on heat generation from wood pellets. Canada is one of the main producer and exporter of wood pellets. 90% of this production belongs to British Columbia. Thus development of ISO standards on off-gassing and self-heating of wood pellets are critical. The rate of off-gassing for a particular biomass traded as commercial products is required to be declared in the MSDS for the product.
