Abstract
Anthropogenic activity induced emissions have led to significantly
increased environmental degradation. The greenhouse gas emissions
generation rates are stimulated by technological innovations including solid
waste management technologies. In this study, categorized household solid
wastes from Ilorin metropolis were collected, sorted and weighed vis-a-vis
population densities and income groups. The classifications are high income
low density area (HILDA), High Income High Density Area (HIHDA), Low
Income Low Density Area (LILDA) and Low Income High Density Area
(LIHDA). Data were processed for potential emission generation from solid
waste management technologies. Result shows that householders generate
high food composition (25%) in comparison with other household refuse
categories. Occupants’ lifestyle with respect to domestic waste composition
is influenced by income level, as high income earners generated more
disposables. Strong nexus exist between household income-population and
all the technologies considered except composting. Order of emission
generation rate per week from the waste management technologies is
landfilling> anaerobic digestion> incineration> composting. Landfill
technology produces the highest CO2 emission (0.0015- 0.65 KgCO2e/week)
for all waste categories and HIHDA householders have the highest values
while anaerobic digestion has the least emission equivalent (0.0 – 0.01
KgCO2e/week). High contributive waste management method to global
warming should be replaced with environment-friendly techniques
