Question: A mixture of decomposable solid waste having chemical formula as C 1 3 6 H 2 2 2 O 1 0 0 N 2 is

A mixture of decomposable solid waste having chemical formula as C136H222O100N2 is sent for anaerobic digester for biogas generation. Using 1 kg of solid waste as a basis, determine the volume of methane and carbon dioxide generated. The specific weight of methane (CH4) and CO2 are 1.395 m3/kg and 0.505 m3/kg, respectively. Atomic weight (unit = kg/k-mole) of C, H, O and N are 12,1,16, and 14, respectively. Anaerobic digestion reaction is given:CaHbOcNd+(4a-b-2c+3d4)H2O
(4a+b-2c-3d8)CH4+(4a-b+2c+3d8)CO2+dNH3
