Aim: A Community-Based Anaerobic Digester was designed in this study for sustainable solid waste management in Ile-Oluji, Ondo state Nigeria. Methodology: Waste samples were collected from selected households for a period of one month and the components and percentage composition were determined. Afterwards, the physico-chemical characteristics of the substrate was investigated and the result used to design a community-based anaerobic digester. Results: The quantity, components and characteristics of waste generated was determined. The rate of waste generation was found to be 0.2kg/capita/day while the organic fraction of the total waste generated was found to be 55.7%. Physico-chemical characterization of the substrate was also investigated.  The pH was found to be 6.36 ± 0.18, while the alkalinity 692.81 ± 78.62.  The moisture content was found to be in the range of 71.20 ± 4.63%. Total solid was in the range 38.91 ± 5.25 while volatile solid was found to be 26.44 ± 2.83. carbon oxygen demand was found to be 834.33 ± 12.61, total phosphorus was in the range 4.20 ± 0.33. The Carbon on a dry weight basis was found to be in the range 60.41 ± 2.38, while nitrogen was found to be 4.79 ± 1.03. The C/N ration was found to be 21.61. The biogas yield ranged from 0 – 320 cm3 and 0 – 380cm3 per litre of substrate for biodegradable-only samples and biodegradable-cow dung samples respectively, for a forty days period of retention. The cylindrical dome type biogas digester was chosen for this study because of its simplicity in design and maintenance coupled with lower set up cost. The optimum volume of hydraulic chamber and gas storage chamber were designed to be the same as 850m3. Volume of fermentation chamber and sludge layer were calculated to be 2014m3 and 246m3 respectively, while the height and diameter of the fermentation chamber were 7m and 17m respectively. Conclusion: Anaerobic digestion of the biodegradable fraction of solid waste is a viable alternative that government and non-government organizations can key into for the improvement of public health especially in developing countries. The standardization of digester design parameters may pose challenges because of varying climatic conditions and complex socio-economic factors across different geographical contexts. Solutions may have to be adapted and localized to achieve a sustainable world.

Waste Management Practices

Rapid urbanization and uncontrolled population growth in the city of Akure create a huge generation of municipal solid waste (MSW) and waste management authority has not been able to manage it properly. This has led to inefficient waste collection methods, insufficient coverage of the collection system and improper disposal of solid waste. This paper investigated municipal solid waste management practices in Akure, Ondo State, Nigeria. Simple random sampling was used in selecting 392 respondents within the eight districts in the study area. Information was collected on socio-economic characteristics of the respondents; nature and compositions of municipal solid waste and solid waste management practices in the study area. The study showed that female respondents (58.2%) were more than male (41.8%) in the study area. Also, a larger proportion of the respondents earned above N40,000 per month. More than one-third of the respondents (37.8%) created squander from vegetable and food remains, next to this were plastic (19.1%), paper (8.2%) and metal waste (6.6%). Further findings showed that the majority of the respondents (66%) do not segregate waste before disposal while the wastebasket was commonly preferred to collect waste due to its affordability. The study concluded that despite the establishment of waste management authority, most of the wastes collected was not sorted before disposal while the majority of the respondents preferred to burn their waste. The study recommended that government and non-governmental organizations should pay much attention to the issue of waste management in the area as waste was not properly managed.

Waste Management System

Kampung Rawajati di Jakarta yang menerapkan sistem pengelolaan sampah berbasis masyarakat merupakan alternatif upaya mengatasi sampah rumah tangga. Penelitian ini bertujuan mengetahui pengaruh sistem tersebut terhadap penurunan berat sampah rumah tangga. Dengan desain studi potong lintang, penelitian ini dilakukan pada sampel 175 ibu rumah tangga yang dipilih secara acak. Hasil penelitian ini menunjukan bahwa pengelolaan sampah berbasis masyarakat dapat menurunkan berat sampah sebesar 28,3%. Analisis regresi linier ganda memperlihatkan bahwa kegiatan pengelolaan yang berpengaruh terhadap penurunan berat sampah adalah kegiatan reuse, daur ulang, dan pembuatan kompos (nilai-p < 0,05). Pembuatan kompos merupakan variabel yang berkontribusi terhadap penurunan berat sampah 657,3 gram setelah dikontrol variabel perancu. Penurunan berat sampah ditemukan lebih besar pada rumah tangga yang mendapat pelatihan. Tidak ada perbedaan penurunan berat sampah menurut jumlah anggota keluarga, penghasilan rumah tangga, dan pengetahuan ibu. Disarankan agar Pemerintah DKI Jakarta dapat melakukan replikasi model pengelolaan sampah berbasis masyarakat kepada wilayah lainnya, dengan memberikan pelatihan pengelolaan sampah kepada masyarakat.Kata kunci : Pengelolaan sampah berbasis masyarakat, berat sampah, pengolahan dan minimasi sampahAbstractKampung Rawajati in Jakarta applies community-based solid waste management system as an alternative way to overcome household waste problem. The objective of the research is to assess the effect of community-based solid waste management on reduction of household waste weight. This study has crosssectional study design and was conducted on 175 housewife as respondent who were selected randomly. The data was collected by interview using structured questionnaire and weighing of household waste. The result shows that the community-based solid waste management can reduce 28.3% of household waste weight (weight before: 1.845 gram/house/day and after: 1.324 gram/house/day). Multiple linear regression analysis shows that variables affecting thereduction of solid waste including re-using activity, recycling, and composting (p-value <0.05). Composting represents the biggest effect to reduction (657.26 gram) after controlled by potential confounders. The reduction was higher among household with waste training and number of trained household member. It was found that number of family member, family income, and mother knowledge are not significant. It was recommended to the Government of DKI Jakarta to replicate this community-based waste management system to other regions by providing training facilities on solid waste management.Keywords: Community-based on solid waste management, waste weight, processing and minimizing of solid waste

Generation of solid waste (SW) is a major problem in urban areas, thus its management is one of the important obligatory functions to not only urban local authority but also for the inhabitants. The citizens expressed their concerns about the waste management system in KCC and associated problems that they are encountering. Waste generation in Khulna City Corporation is around 455 tons of municipal solid waste/day and generation rate is now 0.75 Kg/capita/day on an average. Existing public utility services and facilities are not adequate to meet the demand of disposing these massive amounts of wastes and that’s why several problems are arising. There are some deterrents in the KCC’s solid waste Management system, arising from both the city corporation authority and the citizen of different levels. With a view to address the problem from through community participation, this paper intends to evaluate the potential of community based solid waste management approach in context of Khulna city.

Management of wastes which is a part of the daily activities of man is an important aspect of environmental management. Over the years, there have been concerted efforts made towards adequately solving the problems created by improper waste management and disposal in Nigeria cities. This study, appraises environmental management in cities; a perspective from the Ondo state Waste Management Authority (OSWMA) Akure. The broad objectives of this study are to identify types of wastes managed by OSWMA, describe the attitude and role of residents (household) toward solid waste management, and examine the possible constraints faced by OSWMA, Akure in the discharge of their duties. Samples were drawn from the total number of OSWMA staff and clients served by the authority in the core, transition and peripheral districts of Akure. 53 questionnaires were administered to the staff representing 10% of the total number of staff while 324 questionnaires representing 1% of residents were administered, collated and analyzed using SPSS version 19. The results of the analysis, revealed that majority (81.1%) of the staff respondents opined that the type of waste managed by the Authority is solid waste; using the door to door method of solid waste collection as submitted by 54.5% of the staff. On the other hand, majority of the households’ respondents (81.4%) expressed willingness to pay for service rendered by the authority. Findings also revealed that poor funding was the main constraints faced by the authority. The study therefore recommends proper funding, provision of equipment and facilities needed for smooth running of the authority in order to ensure effective collection and management of waste in the study area.

Organic waste composting is an important waste management practice that can reduce the volume of municipal solid waste and increase crop productivity. A study was carried out in Madhyapur Thimi, Bhaktapur in order to develop understanding of different methods of composting for sustainable solid waste management practices. Solid waste was collected randomly from 50 households in the area and segregated manually. The biodegradable waste was composted through pile (aerobic), aerobic bin, anaerobic (pit) and vermicomposting process. The physico-chemical and microbial analysis of composts were carried out in laboratory whereas significance of composts on crop productivity was tested in the study area. The study showed that 81.4% of the waste generated was biodegradable. The physico-chemical and microbial analyses of the compost samples showed pH range of 7.6 to 8.2 and moisture content of 54.5% to 69.5% for different composts. The maximum temperature (62°C) was observed in aerobic (pile) composting. The nutrient analysis (oganic matter, nitrogen, phosphorus, potassium and C: N ratio) of different composts showed that vermicompost was the most among all the composts. The total bacterial and fungal count varied from 3.91 x 104 to 8.05 x 106 cfu/g and 1.30 x 103 to 3.25 x 104 cfu/g respectively. The vermicompost was found rich in microbial population too. The application of vermicompost at 6.25 mt/ha in the study area resulted in increasing in height, diameter and yield of cauliflower by 15.62%, 37.58% and 38.95% respectively over farm yard manure. The height, diameter and yield of cauliflower grown in different composts was found to be significantly different (P<0.05).
