Abstract :
To determine the Viability of electricity generation
from Municipal Solid Waste (MSW) in Ndola-Zambia.
Place and Duration of Study:
Department of mechanical Engineering (University
of Zambia) in Lusaka Zambia and the City of Ndola
between 2019 and 2022.
Methodology:
The demographic characteristic of the study was
drawn from Ndola with respondents from Ndola city
council, independent Waste pickers, Informal waste
pickers and selected housing units across the city
compromising of High cost , medium cost and Low cost.
To answer to the objectives of the study, the
researcher employed a survey approach with simple
random sampling method where qualitative as well as
quantitative survey questionnaires were used to gather
data, and entered into Statistical Package for Social
Sciences (SPSS), then tabulated and analyzed using
Excel and presented in percentages, frequencies, cross
tabulation and correlation.
The Waste to Energy (WtE) opportunities in Ndola
were carried out in the context of simulating two
scenarios: Biomethanation and Incineration. The
Intergovernmental Panel for Climate Change (IPCC)
default model was presented to estimate emission of
methane from municipal solid waste at kaloko landfill
site Ndola, Zambia.
Results:
Findings revealed that the estimated Net Annual
methane emission potential from solid waste landfills
was 22.09 (Gg/yr.) in the year 2015, giving a net power
Generation Potential of 7.57MW.The maximum methane
production rate by the IPCC default model was
calculated to be 32.2(Gg/yr.) and was observed during
the year 2035, giving a Net Power Generation Potential
of 11.07MW. The power generation potential for Ndola
was estimated at 21MW in the year 2015 resulting in
Energy Generation Potential of 0.52GWh from
incineration.
The Maximum Power generation potential was
estimated in the year 2035 giving a Net Power
Generation Potential from Incineration of 7.87MW.The
Energy Generation potential was found to be 0.75GWh
in the year 2035 at an efficiency of 25 percent.
Conclusion:
Biomethanation can be used as the most suitable
technology in Ndola due to availability of degradable
organic waste stream (134.13Gg/yr.), high efficiency
(25% to 30%); lowest annual capital ($0.1–0.14/ton) and
operational cost. Maintenance of methane emissions has
a direct impact on national energy security and
mitigating potential climate change. It can be assumed
that the increased volume of generated methane, from
increased solid waste in this landfill, is sufficient enough
to be considered for new standard landfill site
construction with methane capturing facilities.
