The aim of this study is to investigate the effects of poor solid waste disposal on a sustainable environment/development in the Mzamomhle urban informal settlement. According to Coffey & Coad, (2010) informal or squatter urban communities pay no municipal taxes, because of their informal status, and this fact has often been used as the principal argument against providing these communities with municipal services.

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

A project report submitted to the Faculty of Engineering, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Master of Science in Engineering. / The design of a waste handling system is closely related to the functioning of the manufacturing system that it serves. The study considered the design of a waste handling system at the factory Printpak Gravure in Industria. The system in use was considered cost inefficient, The system was examlned, operating variables were determined, A model of the system was constructed so that the effectiveness of alternative systems could be compared. The replacement system selected reduced machine downtime and resulted in a lower yearly operating cost. / Andrew Chakane 2018
