1. Problem 1
An Indian city is generating solid waste @ 1.2
kg/day per capita for four months and @ 0.5
kg per day per capita for eight months in a
year. The population of the city is 2.489
million as per the census of 2011. It is planned
to earmark land for land filling of the garbage
for a period of five years. Assuming the
landfill garbage density of 452 kg/m3 and a
10.5 m lift determine the area for (a) 25% soil
in cell volume (b) 30% soil in cell volume.

2. Problem 2
Estimate the landfill area needed to
handle 10 year’s Municipal Solid Waste
for a town of 250,000 people. Assume
per capita solid waste generation is 0.5
kg/day and landfill density of 600 kg/m³,
and a single 3m lift. Assume that 20
percent of the cell volume is soil used for
cover.

3. Problem 3
A landfill site is producing 3500 Nm3
biogas daily. H2S content of biogas is
0.87%. Determine the SO2 emission if this
gas is used in I.C. engines for the
generation of electricity. Also determine
the electricity generation capacity. The
heating value of biogas is 18.58 MJ/Nm3
and only 38.5% of the thermal energy is
converted into electricity by IC engine
coupled alternators.
