The Status

Abstract Background Improper solid waste management (SWM) is a major public health and environmental concern in the urban areas of many developing countries such as Asella Town. The aim of this study was to assess the status of SWM in Asella town. Methods A community-based cross-sectional study design was used to assess the status of improper SWM and associated factors in Asella town. From the total of eight kebeles (smallest administrative unit in Ethiopia) four kebeles were randomly selected using lottery method. The sample size was 413 households. The households were proportionally allocated to each randomly selected kebeles. The data was collected by pretested questionnaire in the local language. Data was entered using statistical software Epi Info version seven and transferred to SPSS version 21. Descriptive data analysis was done to summarize the socioeconomic status of the respondents. Chi-square was used to show the association between the status of solid waste management and different variables. Binary logistic regression was used to determine the potential factors for improper SWM. Result 332 (82.8%), had improper solid waste management practice. Lack of adequate knowledge about solid waste management and not having access to door to door solid waste collection could have contributed to the reported improper solid waste practice. Participants who didn’t have access to door to door solid waste collection service were about three times more likely to practice improper solid waste management when compared to those who had access (AOR = 2.873, 95 CI (1.565,5.273) P = 0.001). Conclusion The study finding showed that, the majority of the residents practiced improper solid waste management. Lack of adequate knowledge about solid waste management and not having access to door to door solid waste collection could have contributed to the reported improper solid waste practice. Therefore, there is a need to enhance the awareness of the community about proper SWM and to improve the door to door solid waste collection service by the town municipality.

Minute Walk

Insufficient staff, inappropriate collection vehicles, limited operating budgets and growing, hard to reach populations mean that solid waste management remains limited in most developing countries; Malawi is no exception. We estimated the willingness to pay (WTP) for two hypothetical solid waste collection services. Additionally, we tested the impact of the WTP question positioning relative to environmental perceptions on respondents’ WTP. The first scenario involved a five minute walk to a disposal facility; the second scenario involved a 30 min walk. Additionally, the order of the question was randomized within the questionnaire. A WTP value of K1780 was found for the five minute walk scenario when the question was placed first, and K2138 when placed after revealing the respondent’s perceptions on the environment. In the 30 min walk scenario, WTP was K945 when placed first and K1139 when placed after revealing the respondent’s perceptions on the environment. The estimated values indicate that there is both a willingness to pay for solid waste services and that there are at least two options that would be acceptable to the community; a pilot scale implementation would be required to validate the hypothetical values, especially given the dependency on problem framing. Community financing should be considered as a sustainable approach to solid waste management in underserved areas.

Collection And Management

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.

The study was conducted to survey the current situation of domestic solid waste generation and management in Hau My Bac A commune, Cai Be district, Tien Giang province in Hau My Bac A village, Cai Be district, Tien Giang province. Data on the status of generation and management were collected through direct interviews with 60 households and placed garbage bags in the households for a period of seven consecutive days a week. The research results showed that the average amount of domestic solid waste generated by each household was about 1-1.5 kg of waste/day, on average, each person generated 0.36 kg/person/day. The composition of domestic solid waste of households was relatively different, mainly organic waste, accounted for 47.88% higher than the other components. Plastic, plastic bags accounted for 24.65%, metals 2.19%, paper and carton 9.89%, foam box accounted for 4.15%. The wood, fabric, rubber, and glass were negligible. Hazardous wastes were not found in the study period. Currently, the collection was not met the demand of efficient solid waste collection due to the lack of facilities and the workforce. The rate of solid waste collection was only about 40-55%. Local domestic solid waste managers have not been paid adequate attention to the overall management of solid waste. Local residents in the study area were not fully aware of the harms of domestic solid waste, did not actively participate in solid waste management activities leading to the difficulty in the management. The active participation of the community and strict enforcement of the environmental protection law can make an important contribution to the full management of solid waste in the study area.

Background: Planning and optimum waste management as the first step has need to waste characterization studies including the existing status, quantity and quality (physical composition) of generated solid waste at University. The aim of this study was evaluation of the existing situation, identification of the quantity and quality of solid waste in one of Iranian military universities. Materials and methods: This cross-sectional research was done in one of the Iranian military universities. The status of waste management was determined using self-made checklist (valid and reliable) and site visits and documents analysis. Quantity, quality, and physical analysis of waste was determined by weighting via trained personnel. The collected data were analyzed using SPSS 18 software and descriptive statistical methods. Results: Existing situation of waste management which has 58 score was weak in comparison with desirable situation as 112 score. The average weight, capitation and density of the waste were 419 kg/d, 288 gpc/d and 105.3 kg/m3 respectively. Putrescible waste 40.15%, paper and cardboard 13.99%, soft plastics 13.10%, dried plastics 6.35%, wood and plant waste 6.14%, glass 5.64% and ferrous metals 0.82% were the predominant components. Conclusion: Despite separation of valuable dry wastes, waste management status in this university is not desirable. . 40% of total wastes were valuable and recyclable. Recycle is a best-recommended procedure, which can lead to volume and capitation reduction and decreasing of collection, transport and disposal costs nearly 50%.

Nowadays, in the European Union selective solid waste management be-longs to important responsibilities of municipalities. In Solid Waste Management (SWM) the main operational task is to set a schedule for solid waste collection and to find optimal routes for garbage trucks so that the total costs of solid waste collection service can be minimized subject to a series of constraints which guarantee not only fulfillment of SWM’s obligations but also desirable level of quality of that service. Optimization problem of garbage trucks routing is a special case of rich Vehicle Routing Problem as it has to cover following constraints: pickup nodes (clients) must be visited during their predefined time windows; the number and capacity of depots and specialized sorting units can-not be exceeded; each garbage truck can be assigned to at most one depot; each route should be dedicated to collecting one type of segregated solid waste, and the route must be served by a garbage truck which can collect that type of solid waste; availability of garbage trucks and their drivers must be respected; each garbage truck must be drained at a specialized sorting unit before going back to the depot. This paper contributes with a new Mixed-Integer Programming (MIP) model for the Selective Solid Waste Collection Routing Problem (SS-WCRP) with time windows, limited heterogeneous fleet, and different types of segregated solid waste to be collected separately. Utilization of MIP for solving small-sized instance of the Fleet Optimization Problem for Selective Solid Waste Collection (FOPSSWC) is and obtained results are reported.

Solid waste management practice is one of the crucial components in developing a sustainable city. The practice of sustainable solid waste management among the community is reflecting one of the sustainable community features. However, developing a sustainable community is not an easy task where it requires commitment from multiple stakeholders. Hawker's community is essential in urban areas where it plays a vital role in economic development and environmental sustainability. Therefore, this study was conducted to examine hawker's community's knowledge, awareness, and practices in solid waste management. This study used a questionnaire as the primary research instrument. A total of 105 respondents participated in this study, where they are hawkers in Georgetown, Penang, Malaysia. Descriptive analysis was applied to examine the hawker's community's awareness, knowledge, and practice on sustainable solid waste management, which focuses on recycling and composting. This study found out that the awareness of respondents on sustainable solid waste management is high. However, the knowledge of respondents is at a moderate level. This study also reveals that the respondent is reluctant to practice sustainable solid waste management because of time constraints and inconvenient facilities. This finding is significant to local authority and government agencies to develop sustainable community framework in an urban area.
