Waste Characterization
Relatively Inert Moderately Decomposable Decomposable
Methane Generation Potential L0 (m3 methane/tonne) 20 120 160
Methane gas density: .6557 kg/m3 (source = BC Gov. )
160 x .6557 x 25 (CH4 = 25x times more than CO2e)/1,000 = 2.6 metric tonnes CO2e diverted per metric tonne food waste. Carbon cost @ $50mt = $50mt x 2.6 = $130 mt
1 metric tonne of food waste dehydrates to 200kg of usable biomass.
Combustion of biomass displaces natural gas as the fuel. Carbon dioxide emissions are deemed to be “carbon neutral� inmost HGH programs because the carbon dioxide is part of the carbon-cycle. Based on 8,610 BTU per pound the emission reduction is .00387 tonnes carbon dioxide per pound of biomass combusted (8.5 tonnes CO2e per metric tonne of biomass). Brightspot Climate Inc.
