The study focused on waste management and environmental sustainability in Uyo, the capital city
of Akwa Ibom State. To achieve this objective, two hypotheses were formulated using waste
recycling and waste landfill as variables of waste management. This study relied on Ecological
Modernization Theory (EMT) as the theoretical framework. The survey research design was used
and the study population was 1,457,020. 400 respondents were chosen as sample size using Taro
Yamane’s sample size determination technique. Data analysis was done using simple linear
regression analysis. The findings revealed that waste management practices significantly
influence environmental sustainability in Uyo Capital City. Specifically, the findings revealed
that waste recycling and landfill practices have significant effect on environmental sustainability
in Uyo Capital City. Based on the findings, it was recommended that Akwa Ibom State Government
should ensure that waste recycling is incorporated into the Akwa Ibom State Environmental
Protection and Waste Management Agency (AKSEPWMA) frameworks, with periodic reviews to
support its adoption as part of sustainable development goal. Also, the environmental regulatory
agencies such as Akwa Ibom State Environmental Protection and Waste Management Agency
(AKSEPWMA) and the Akwa Ibom State Ministry of Environment should strengthen monitoring
and enforcement mechanisms to ensure all waste landfill comply with national and international
environmental standards.
