The proper handling and disposal of medical waste in accordance with national guidelines is very important. This study was undertaken to investigate the state of medical waste and management practices in different hospitals in the north-eastern Free State Province, South Africa. A random sample of ten (10) hospitals was selected. Observation of operations was carried over a period of six months. A stratified random sample of 138 staff members spread across the ten medical facilities was selected and face-to-face interviews were conducted. The hospitals were grouped into 3 categories namely large, medium and small in terms of the number of hospital beds. Data collection through observation and covered waste generation, storage, handling, transportation, treatment and management procedures. Data analysis made use of SPSS to generate descriptive statistics, correlation coefficients and t-tests in hypothesis testing. The findings reveal that medical personnel do not treat medical waste as specified in official guidelines, there is no formal training for personnel, medical waste is not a key priority, there are low levels of environmental awareness, inappropriate treatment of waste at some sites, and inadequate budget allocations for medical waste management. These findings indicate that there is an urgent need for addressing issues of awareness for managers, better on-the job training for personnel, better systems for on-ward conveyance of waste from facilities to official medical waste treatment plants, an up-grade of existing incinerators and a consistent schedule of data capture should be implemented. / Thesis (Msc Env Science) North-West University, Mafikeng Campus, 2013

Disposal of regulated waste has become a major challenge for the generators. Disposal of such waste is regulated by local, state and federal agencies and the problem is intensified because of liability issues, public perception and increasing cost. This document describes the mechanical design, installation and testing of a system that employs bioremediation to disinfect regulated medical waste. Currently marketed treatment systems generally use either heat or extreme pH to disinfect medical waste. The most common and widely accepted of these, incineration, is rapidly losing favor because of undesirable emissions and hazardous by-product. The system described in this document is the first to use a biological process. The advantages of using this system include the absence of harmful effluents or emissions, low cost of operation, reduction of waste volume and disposal directly into landfill and sewers. The evolution of system design from conceptual stage to the design of a system for Lewis-Gale hospital is described. A general overview of the components is presented and the selection and testing criteria are explained. The components used in Lewis-Gale hospital are described with a detailed layout scheme. A detailed failure analysis was done for each component used in Lewis-Gale hospital. This is presented with contingency plans developed for prolonged system failure. Finally, the operators manual developed for the Lewis-Gale hospital is included. / Master of Science
