The same approach can be used to quantify total GHG savings/
avoidance from the ISWM system. It should be noted that the effect
of diverting organic waste from the landfill in GHG emissions
reduction would be accounted in GHG emissions from the existing
landfill. Therefore, when aggregating technologies, GHG savings
from individual treatment methods via avoided organic waste
landfilling should be excluded in order to avoid double counting.
Net GHG emissions from ISWM system can be quantified as
follows;
