Raw municipal solid waste (MSW) collected from a city contains 70% decomposable material that can be converted to methane. The water content of the decomposable material is 35%. An elemental analysis of the decomposable material yields the following mass percent: C:H:O:N:other = 44:6:43:0.8:6.2.
The methane production of the decomposable material is governed by the following stoichiometric relation:
CaHbOcNd + nH2O → mCH4 + sCO2 + dNH3
Given atomic weights: C = 12, H = 1, O = 16, N = 14.
The mass of methane produced (in grams, round off to 1 decimal place) per kg of raw MSW will be _______.
