Question

- A landfill initially received 10,000 tons/day of waste. This receipt rate increases 10% per year. The landfill is closed at the end of the fourth year. Calculate the yearly gas production for 20 years after opening. What is the peak gas production in m
^{3}/yr.

Step 1

Consider landfill emission constant as 0.305 per year.

Consider generation potential as 100 m^{3}/tonne.

Step 2

Find the mass of wet waste per year for year 1 using the relation;

Step 3

Calculate the mass of wet waste per year for year 2, 3, and 4 by adding 10 % increment of receipt ra...
