The Membership Function

An informal landfill is an open dump that pollutes the underground environment because it lacks an impervious liner. The leakage of such a landfill is unidirectional and thus difficult to directly test. This study uses electrical imaging survey to evaluate the pollution of the underground environment of an informal landfill for municipal solid waste in Beijing. We hypothesize that every location has a specific resistivity resulting from the leachate. We use the membership function of fuzzy mathematics to quantitatively represent the pollution of the underground environment in the sanitary landfill. The results are consistent with borehole data.

A research study was carried out aiming to investigate the possibility of treatment of vegetation water in a anaerobic digester like a sanitary landfill. This vegetation water originates from olive oil production. The results, obtained from lysimeters filled with Municipal Solid Waste, show very high gasification and reduction of the organic load of vegetation water, with no inhibitory effect on waste degradation processes providing the vegetation water is added to an active methanogenic system or buffering the landfill system during the acid phase. The inhibitory influence of compounds, like polyphenols, which can be present in vegetation water in large amounts, has been studied.

AbstractTwo types of municipal solid waste (MSW), newly arrived and 2 weeks old, were sampled from a sanitary landfill in Pulau Pinang, Malaysia at a fortnightly interval and kept under field conditions for 2 weeks. A total of 480 kg of each type of MSW was sampled to study species composition and impact of delays in cover soil applications on filth fly emergence. Out of 960 kg of MSW sampled, 9.2 ± 0.5 flies emerged per kilogram. Weekly adult fly emergence rates of newly arrived and 2-week-old waste did not differ significantly and MSW remained suitable for fly breeding for up to 1 month. Eight species of flies emerged from the MSW: namely, Musca domestica, Musca sorbens, Synthesiomyia nudiseta, Hydrotaea chalcogaster, Chrysomya megacephala, Lucilia cuprina, Hemipyrellia ligurriens and Sarcophaga sp. Newly arrived waste was determined to be the main source for M. domestica, C. megacephala and L. cuprina in the landfill owing to significantly higher mean emergence compared with 2-week-old waste. Musca sorbens was found in newly arrived waste but not in 2-week-old waste, suggesting that the species was able to survive transportation to landfill but unable to survive landfill conditions. Hemipyrellia ligurriens, H. chalcogaster and S. nudiseta were not imported into the landfill with MSW and pre-existing flies in and around the landfill itself may be their source. The results show that landfills can be a major source of fly breeding if cover soil or temporary cover is not applied daily or on a regular schedule.

The Cost

Sanitary landfill remains the most common methodology for final treatment and disposal of municipal solid waste worldwide, the cost per tonne depends on its scale. The bigger the landfill, the cheaper the cost of treatment, so the consortium of municipalities is the solution to achieve an economic scale. However, the growth of waste production introduces pressure for adequate solutions and therefore has been increasing sanitary landfill site selection studies. This study proposes a methodology for siting sanitary landfills and optimising the transport of municipal solid waste for a locality in the state of São Paulo, Brazil. Environmental, social, and economic criteria were established. Their correlated attributes were categorised into suitability levels and weighted according to multiple decision analysis. The data were organised and mapped within a geographic information system. Considering sites where landfills are prohibited, two scenarios were generated. The Mixed-Integer Quadratic Programming mathematical model is used to minimise the costs of transporting municipal solid waste and operating sanitary landfills. In Scenario 1, the results indicated that 64% of the area was suitable as a potential sanitary landfill site, 9% of the area exhibited medium suitability, and 27% of the area was classified as restricted. In Scenario 2, the results indicated that 25% of the area was suitable as a potential sanitary landfill site, 4% of the area had medium suitability, and 71% of the area was classified as restricted. The optimal solutions for Scenario 1 and Scenario 2 enabled sites to be determined for five landfills and four landfills, respectively.

Different Levels

Most of the municipalities in the Gulf region are facing performance-related issues in their municipal solid waste management (MSWM) systems. They lack a deliberate inter-municipality benchmarking processes. Instead of identifying the performance gaps for their key components (e.g., personnel productivity, operational reliability, etc.) and adopt proactive measures, the municipalities primarily rely on an efficient emergency response. A novel hierarchical modeling framework, based on deductive reasoning, is developed for the performance assessment of MSWM systems. Fuzzy rule-based modeling using Simulink-MATLAB was used for performance inferencing at different levels, i.e., component, sub-components, etc. The model is capable of handling the inherent uncertainties due to limited data and an imprecise knowledge base. The model’s outcomes can exclusively assist the managers working at different levels of organizational hierarchy for effective decision-making. Performance of the key components assists the senior management in assessing the overall compliance level of performance objectives. Subsequently, operations management can home in the sub-components to acquire useful information for intra-municipality performance management. Meanwhile, individual indicators are useful for inter-municipality benchmarking. The model has been implemented on two municipalities operating in Qassim Region, Saudi Arabia. The results demonstrate the model’s pragmatism for continuous performance improvement of MSWM systems in the country and elsewhere.

Current waste management strategies are shifting from waste disposal to recycling and recovery and are considering waste as a potential new resource. This paper aims to quantify reusable and recyclable fractions with status of material recovery from municipal solid waste (MSW) in Kathmandu Valley of Nepal. 550 households, 110 institutions and 110 commercial establishments were sampled to compute the generation, composition and quantify reusable and recyclable fraction of solid waste. In addition, 120 scrap shops were surveyed randomly from Kathmandu Valley to estimate the amount of resource recovered for economic benefits. As per results, the average per capita MSW generation can be estimated at range of 0.25 kg day-1 to 0.47 kg day-1 in municipalities of Kathmandu Valley. Based on these generation rates and population for the year 2011, the total MSW generation of the five municipalities of Kathmandu Valley was estimated to be 620 metric tonnes day-1. The major content of reusable and recyclable materials in MSW comprised with an average of 44% that is equivalent to 271 metric tonnes day-1 among which only 52% (i.e. 140 metric tonnes day-1) of these materials were found to be recovered during survey. The key materials that have been recovered are papers, plastics, metals, glasses, and batteries. Recovery of reusable and recyclable materials not only helps to minimize the quantity of solid waste for land filling, but also provides a potential source of livelihood for the urban poor.

The population growth in many urban cities and its urban activities in developing countries have resulted in an increased generation rate of municipal solid waste(MSW), an important issue. In the process of municipal solid waste management (MSWM) system in which, collection activities contributed the most of total cost that is paid for MSW collection activities by city’s citizen; and transport activities are required 60-70% of total cost that is the total expenditures spent on the transport, transfer, disposal and treatment of MSW by city authorities. Hence optimization of routing system, systematization of collection, transport and transfer activities is the important components for an effective MSWM system. This article describes the current problems and the improvement of the management activities in a city of Chandigarh. An integrated MSWM assessment model is proposed and used as a decision support tool for daily efficient operations such as collection/ transport path management, load balancing within vehicles, fuel consumption management by using GIS application. In addition, a simple optimal routing model is proposed to achieve the minimum cost/distance/time efficient collection and transport path for MSWM.DOI: http://dx.doi.org/10.3126/on.v9i1.5729
