Let's see if it makes sense for a major US city to utilizeits municipal solid waste (MSW) as a sustainable biomass feedstock.Using Chicago as a model Mid western US city where the average citizen produces MSW, how much bioenergy can be recovered from the entire population of the city? Compare this figure with the amountof bioenergy that could be produced by growing high yield"energy crops" on a portion of Illinois' vacantfarmland - amounting to 10% of total land area of the state.
