Asked Sep 28, 2019

A landfill receives 10000tons/day of waste. This receipt rate increases 10% per year. The landfill is closed at the end of the fourth year. Using the exponential model calculate the yearly gas production for 20 years after opening. What is the peak 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 rate.

Similarly, calculate and...
