WASTE DISPOSAL TECHNIQUES AND PLANNING IMPERATIVES IN PORT HARCOURT METROPOLIS

Solid waste collection is a crucial aspect of urban sanitation, especially in rapidly growing cities like Port Harcourt, Nigeria. This study investigates the waste disposal techniques in Port Harcourt metropolis. The study was guided by two research question. Using experimental survey research designs, data were collected from 175 solid waste workers employed by service providers to the Rivers State Waste Management Agency (RIWAMA). Findings revealed that the primary source of waste was residential areas (49.1%), followed by institutional, industrial, and commercial sources. Waste composition included food waste (22.3%), plastic (19.4%), sanitary waste (14.3%), and other hazardous materials such as glass and heavy metals. While nearly half of the respondents reported using RIWAMA receptacles for waste disposal, a significant number still engaged in unsafe practices such as open dumping (19.4%) and burning (8.5%). These practices expose waste workers to a range of occupational hazards, including respiratory infections, skin diseases, and musculoskeletal injuries, due to poor handling techniques and lack of personal protective equipment. The study also found that many waste workers operate under informal employment conditions, lacking adequate training, healthcare access, and safety regulations. The research highlights the urgent need for policy interventions, improved waste infrastructure, public education on proper waste disposal, and better protection for waste workers. Strengthening institutional frameworks and promoting source segregation can significantly reduce health risks and improve environmental quality in Port Harcourt Metropolis.
