Using the energy content (wet basis) of the waste components given in the table below, calculate the overall energy content of the waste having the composition shown. You can assume 100 lb of waste to make this easier. Then determine the composition of the left-over waste if 80 % of the cardboard, 60% of the yard waste, 50% of the paper, 30 % of the metals and 20% of the plastics are recovered or recycled. How does this affect the total energy content of the discarded waste? How about the energy content per mass (wet weight)?
