An Assessment of the Adequacy of the Methods Of Domestic Solid Waste Management in Kisii Town, Kenya

Urban domestic solid waste is increasingly being generated in many urban centres including middle sized towns. In many urban areas in developing countries there’s a growing need and awakening for meeting the waste disposal for the ever increasing population. This paper examines and analyses the varied treatment and disposal methods of domestic solid waste employed in Kisii town. The specific objective of the study include: to assess the adequacy of the available management systems of handling domestic solid waste (DSW) in Kisii town. A mixed methodology approach was taken into consideration. A sample of 110 households was obtained using the multi stage stratified sampling method. Data collection methods of the sampled size involved the use of questionnaires to 110 householders and direct interviews to 2 county officers in charge of DSW and observation integrated with photography. Data analysis was carried out using methods such as use of tables and graphs through SPSS. The results indicate that the storage facilities are inadequate for the residents, the collection times are not only insufficient but also irregular, the transportation means employed are limited, and disposal and treatment of the DSW is limited to mainly open dumping at the overfilled Nyambera dumpsite. In conclusion, the management methods of the DSW are inadequate and pose severe health risks to the residents of Kisii. It is recommended that, for effective domestic solid waste management adequate bins should be provided in the town, collection should be regular and indiscriminate in all estates, recycling, re-use, reduce and energy recovery should be introduced to move from challenges to opportunities. Finally, an integrated model of integrating CBOs and private groups in management of DSW is suggested to ensure sustainable solid waste management.

Effects of anthropogenic activities on the heavy metal levels in the clams and sediments in a tropical river.

The present study aimed to assess the effects of anthropogenic activities on the heavy metal levels in the Langat River by transplantation of Corbicula javanica. In addition, potential ecological risk indexes (PERI) of heavy metals in the surface sediments of the river were also investigated. The correlation analysis revealed that eight metals (As, Co, Cr, Fe, Mn, Ni, Pb and Zn) in total soft tissue (TST) while five metals (As, Cd, Cr, Fe and Mn) in shell have positively and significantly correlation with respective metal concentration in sediment, indicating the clams is a good biomonitor of the metal levels. Based on clustering patterns, the discharge of dam impoundment, agricultural activities and urban domestic waste were identified as three major contributors of the metals in Pangsun, Semenyih and Dusun Tua, and Kajang, respectively. Various geochemical indexes for a single metal pollutant (geoaccumulation index (I geo), enrichment factors (EF), contamination factor (C f) and ecological risk (Er)) all agreed that Cd, Co, Cr, Cu, Fe, Mn, Ni and Zn are not likely to cause adverse effect to the river ecosystem, but As and Pb could pose a potential ecological risk to the river ecosystem. All indexes (degree of contamination (C d), combined pollution index (CPI) and PERI) showed that overall metal concentrations in the tropical river are still within safe limit. River metal pollution was investigated. Anthropogenic activities were contributors of the metal pollution. Geochemical indexes showed that metals are within the safe limit.

Prediction of Urban Waste Disposal Based on ARIMA Model

The amount of municipal solid waste(MSW)transportation has become an important basis of handling urban domestic waste, at the same time, accurate predictions of time series data have motivated the researchers to develop innovative models for urban solid waste management.Therefore, predicting the MSW transportation amount in a scientific manner is one of the most essential parts of the urban waste management work. Based on the raw data of MSW transportation amount from 1993 to 2012 of Wuhan city, the capital of Hubei province, this paper chose Autoregressive Integrated Moving Average Model(also called ARIMA model), used Eviews software to process the data and test various effective inspection, then made a prediction of the amount of MSW transportation of Wuhan, and got access to the conclusions through comparing the original data and predicted one. The results showed that the predicted value of the amount of MSW transportation in 2013 was consistent with the original one, and would reach 214.82 wt in 2014. The results also demonstrated that, the MSW transportation amount prediction based on ARIMA model is practicable due to its high applicability and accuracy, offering decisive information for the urban environmental planning and urban domestic waste controlling.

Evaluation of Green Cement Manufacturing Seeking Joint Treatment for Urban Refuse

Sanitary landfill, Burning, Compost are the main method to dispose gabage in China.If urben refuse is put into the cement kiln, processing it, producing cement, it will benefit all. This mature method has no influence on neither the cement production nor the quality of cement products,however the indexes of all emissions in the manufacturing meet the national standards. Statistics show the heat generated by every ton of waste is equal to that of 183kg standard coals; the cinders are mixed in cement during the treatment process, thus 107kilograms substitute raw materials can be generated by every ton of waste, and 6 to 7 percent are added. Moreever, it reduces carbon dioxide emission 8000 tons for every 10,000 tons waste. This paper concludes: the utilization of cement kiln to incinerate domestic waste has obvious advantages in environmental protection and total investment does not cost much. The municipal engineering construction has the priority to use the products from domestic treatment cement factories, and domestic waste incineration cement factories should be under self-management. Also supportive policies as well as the readjustment of waste treatment management and interest pattern can promote the development of treating urban domestic waste by cement production.

Study on Dry-basis Separation Test for Urban Residential Waste

Abstract Since its implementation in 2000, China's urban domestic waste separation pilot program has achieved little success. The root cause lies in the lack of moisture control for crude waste from the source. If wet-basis waste is placed in bags, collected by waste bins/cans and transferred by vehicles, waste is difficult to be separated for collection, transport and disposal, and a large amount of materials lose the value of recycling. High moisture and rapid reproduction of microbes leads to serious pollution, collection and transfer of daily waste upon generation and soaring transport cost. Unsorted waste also greatly increases the difficulty in collection, transport and disposal. The study on dry-basis separation test helps achieve the separation and temporary storage of domestic waste through moisture control, facilitating the low-frequency placement, collection and transport of domestic waste. Based on the test, a new concept of low-frequency direct transport and separation of domestic waste on a dry basis is raised, and corresponding key technical equipment to be developed is specified.

Study on the Prediction Model of the Proportion of Each Type of Urban Domestic Plastic Waste

In order to conduct the integrated management in the whole process of plastics waste management, plastics waste generation should firstly be studied, especially the generation of each kind. The results of factors acting during the generation process should also be studied. Using Beijng as an example city, this paper established a predicting model for the generation and proportion of each shape and component of plastics waste, and analyzed the generation characteristics and trend of plastics waste in Beijing according to the predicting results. In terms of shape, the plastic film has the largest proportion. While in terms of component, PP and PE have the largest proportion among all the components.
