For a city of 3 million individuals discard 4lbs of solid waste per capita. Thirty percent of this waste is diverted to recycling. The remainder is compacted to a density of 1300 lb/yd3 and is landfilled into two 12-foot lifts per year.  Assume that 18% of the volume will be necessary for daily cover. Find: a) Volume waste + cover

A city receives 42 tons per day of a solid waste stream with chemical formula C4H17O to their waste to energy facility each day. Estimate the air requirements to combust this waste in cubic ft per day. Assume specific weight of air is 0.075 lb/cu ft and that air is 21% oxygen by weight.

With an assumption that the volatility of Waste Management (WM) is 14.49% per year, corresponding to ______ per month, ______ per week, and ______ per day.   A.   4.26%        /           2.07%              /           0.91%   B.   4.18%        /           2.04%              /           0.91%   C.   3.16%        /           2.01%              /           0.91%   D.   1.21%        /           0.28%              /           0.06%

Estimate the total theoretical amount of air that would be required under aerobic conditions to oxidize completely an organic waste with a chemical formula of C120H180O80N2.
