It is generally accepted that organic materials in landfill will decompose as follows:
50% directly into CO2 and 50% into methane CH4
Greenhouse Gas (GHG) affect is as follows:
500 lbs. raw food waste (@ 80% water) = 100 lbs. organic material
100 lbs. x 50% CO2 = 50 lbs. CO2
100 lbs. x 50% CH4 = 50 lbs. x 23 (more damaging than CO2) Total CO2 equivalent =1,200 lbs.
1,200 lbs. CO2 equivalent = .55 MT CO2 equivalent per day
