Perceptions of workers on the benefits of institutional source sorting: A case of the Council for Scientific and Industrial Research - Institute of Industrial Research (CSIR-IIR), Accra, Ghana
The management of solid wastes at the workplace in Ghana is characterised by mixed wastes pickup delays, dustbin overflows and leakage of plastic bags into the environment. Benefits from the pilot of source sorting as a mitigation measure at the workplace are unavailable in literature. Hence, the study employed descriptive statistical tools to assess the advantages of a piloted source sorting system at the CSIR-IIR. The sampled size was 100 staff with an 80% questionnaire recovery rate. The analysis of data showed that, the implementation of segregation at source transformed the social approach of workers towards waste management. Most workers (97.7%) preferred sorting their wastes at source irrespective of the location of the generation point. A congenial environment was created by the source separation infrastructure, which made staff worked better, (70% responses). The majority of staff (95.2%) confirmed the savings made by the Institute on the cost of landfilling. The sorting at source improved cleanliness of the compound (97.6% responses) and eliminated open-air burning of wastes (95.1% responses). In all, the source segregation was beneficial to the social, economic and environmental well-being of staff and management of the Institution.
