Imagine you have been hired as a consulting engineer by a city to investigate the possible use of landfill gas generated by the expected decomposition of different types of municipal solid waste. for your calculations, assume maximum theoretical landfill gas production will be applicable by neglecting the production of new bacterial cells as described in our textbook. (a) estimate the percent (by volume) of landfill gas that is methane from a rapidly decomposing waste with an assumed composition of c68h111o50n. (b) estimate the percent (by volume) of landfill gas that is methane from waste hardwood lumber, which has an assumed composition of c88h126o55n3.
