- 148 -Appendix C: Carbon release and sequestration from wood in landfillCalculations to determine the carbon dioxide and methane release from landfill as wood decomposesAssumed 50% of wood mass is carbon.Molar mass carbon = 12So 1kg wood = 0.5 kg Carbon.g/mol.Molar Mass CO 2 = 44 g/mol0.5 kg = 41.67 moles of carbon. Molar Mass CH 4 = 16 g/mol41.67 moles of CO 2 41.6666 moles of CH 441.6666 x 16 = 666.6741.67 x 44 grams = 1833.34 grams.gramsSo 1 kg wood --> 1.83 kg of CO 2Or 1 kg carbon --> 3.67 kg CO 2So 1 kg wood --> 0.67 kg ofCH 4Or 1 kg carbon --> 1.34kgCH 4
