Cassava Waste

Agricultural products such as cassava produce huge amounts of waste when processed into consumable goods. The waste generated is generally considered to contribute largely to environmental pollution. This study therefore investigates the waste management practice that is adopted by cassava processors in Ogun State, Nigeria. Five local government areas (LGAs) dominant in processing cassava were selected for the study on the basis of spatial location distribution, landmass, and population. The survey involved the use of structured questionnaires administered to cassava processors of the selected LGAs. The Statistical Package for Social Sciences (SPSS) software application and descriptive statistics were used for data analysis. Results of the analysis show that the majority (70%) of the cassava processors are females. Cassava peel constitutes 10% of the waste produced, of which 91% is heaped at refuse dumps in most communities. Results also reveal that 86.3% of cassava residues are used for animal feeds. Other findings show that the peels, when dried, are used as biofuel for cooking and there is a significant potential for biogas production. From the data captured from respondents during the study, most processors are willing to pay for an improved waste management system. The study therefore recommends the proper waste management of cassava waste to minimize environmental pollution.

Cassava Waste

Agricultural product like cassava produces huge amounts of waste when processed to consumable goods. The waste generated is generally considered to contribute largely to environmental pollution. This study therefore investigates the waste management practice that is adopted by cassava processors in Ogun State, Nigeria. Five (5) Local Government Areas (LGAs) dominant in processing cassava were selected for the study on the basis of spatial location distribution; landmass and population. The survey involved the use of structured questionnaires administered to cassava processors of the selected LGAs. The Statistical Package for Social Sciences (SPSS) software application and descriptive statistics were used for data analysis. Results of the analysis show that majority (70%) of the cassava processors are females. Cassava peel constitutes 10% of the waste produced, of which 91% are heaped at refuse dump in most communities. Results also reveal that 86.3% of cassava residues are used for animal feeds. Other findings show that the peels when dried are used as bio-fuel for cooking and there is a significant potential for biogas production. From the data captured from respondent during the study, most processors are willing to pay for an improved waste management system. The study therefore suggests proper waste management of cassava waste to minimize environmental pollution.

Purpose. Characteristics of the easily decomposed organic municipal solid waste flow: evaluation of composition, main components content and determination of possible recycling directions. Methods. System analysis methods, statistical processing of data were used. Results. Almost 60% of the municipal solid waste mass was composed of components containing biodegradable carbon – food and garden wastes, paper and cardboard, textiles, nappies, rubber and leather, wood. The total content and correlation between the main components depend on local conditions and change over time. The coefficient of variation was chosen as a criterion for assessing the variability of the content of individual components in the MSW total mass. It was shown that the most variable was the content of rubber and leather, as well as wood; the most stable characteristic was the content of food waste. The municipal solid waste management practice is to dispose of easily decomposed organic waste into landfill and dumps, which are sources of environmental pollution by e.g. greenhouse gases. The exception is some part of paper and cardboard. Given the obtained characteristics of wastes containing biodegradable carbon, we present the main directions of its recycling that are possible today. Conclusions. A group of wastes containing biodegradable carbon constitutes a significant proportion of MSW. The correlation between the different components of this group is a characteristic feature of the generation source and should be taken into account by developing an effective system of waste management for a particular city or region. The current waste management practice leads to waste disposal into landfill and dumps, which are sources of environmental pollution. On the other hand, such waste can be efficiently recovered, especially the largest by weight food, garden waste and paper and cardboard. However, a necessary condition for this purpose is their separation from the general municipal solid waste stream in the moment of waste generation.

This paper examines solid waste transportation in Ado-Odo/Ota Local Government Area of Ogun State. Adequate transportation of solid waste is one of the major challenges of waste managers in Nigeria because of inherent factors ranging from dearth of transport infrastructure to poor attitude of residents. Data were collected through the aid of questionnaires, personal observations, visitations to some villages and towns as well as dumpsites. The questionnaires were divided into two parts: household respondents and solid waste management staff. The data obtained were analyzed using Descriptive Statistics, Factor Analysis and Item Analysis. From the analysis of the data obtained from household and waste management respondents the mean and standard deviation reflect high degree of correlation and concurrence. From the principal component analysis of both the household respondents and waste management staff, there are two principal factors respectively that should be given higher consideration in solid waste management in Ado-Odo/Ota Local Government Area. These factors include waste collection and disposal method, frequency of collection and reliability of waste vehicles. Based on these findings, the study concluded that attitudinal change on the part of the household, government intervention on road maintenances, and adequate maintenance of PSP vehicles will go a long way in reducing the heaps of refuse and indiscriminate dumping of solid wastes in the entire vicinity of Ado-Odo/Ota Local Government Area in Ogun State, Nigeria.

Medical Waste Management

Background:Poor medical waste management has been implicated in an increase in the number of epidemics and waste-related diseases in the past years. South Africa is resource-constrained in the management of medical waste.Objectives:A review of studies regarding medical waste management in South Africa in the past decade was undertaken to explore the practices of medical waste management and the challenges being faced by stakeholders.Method:Published articles, South African government documents, reports of hospital surveys, unpublished theses and dissertations were consulted, analysed and synthesised. The studies employed quantitative, qualitative and mixed research methods and documented comparable results from all provinces.Results:The absence of a national policy to guide the medical waste management practice in the provinces was identified as the principal problem. Poor practices were reported across the country from the point of medical waste generation to disposal, as well as non-enforcement of guidelines in the provinces where they exit. The authorized disposal sites nationally are currently unable to cope with the enormous amount of the medical waste being generated and illegal dumping of the waste in unapproved sites have been reported. The challenges range from lack of adequate facilities for temporary storage of waste to final disposal.Conclusion:These challenges must be addressed and the practices corrected to forestall the adverse effects of poorly managed medical waste on the country. There is a need to develop a medical waste policy to assist in the management of such waste.
