A sample of dry solid waste has the following composition: 531 g carbon (C), 133 g hydrogen (H), and 335 g oxygen (O). How many Litres of air is required to combust the waste? Answer: Check
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)?
The majority of municipal solid waste is 64% paper. What ways would you suggest to reduce paper waste?

Determine leachate generated in a cell in a 12-month period. You may assume that: -Percolation through the cover is 15in -Water consumed by waste decomposition is negligible (Life 1 contains mostly fresh waste) -Water loss as water vapor in landfill gas is negligible (again due to fresh waste) -Initial moisture content in fresh waste = 0.20 -Weight of waste in the lift = 3000 lb/yd² -Weight of cover = 1500 lb/yd² -The following sketch depicts water in and out of a waste lift.
