Domestic Solid Waste

The increase in solid waste generation is incompatible with solid waste management (SWM). Padang city have a small processing percentage of 5% through composting and recyling. Improper and nonoptimal SWM lead to many obstacles including climate change, water and soil contamination, to creatures life disturbance. By conducting Impact Assessment and Contribution Analysis, this study examines the most impact contributor of unit processes in four scenarios of domestic solid waste management in Padang City. Scenario 0 presents the existing condition; scenarios 1, 2, and 3 present the improvement of Scenario 0 in recycling percentage rate and technology implementation in a row by composting, incineration, and anaerobic digestion. CML2001, impact assessment method by Center of Environmental Sciences of Leiden University, is used to assess the environmental impact of Global Warming Potential (GWP), Acidification Potential (AP), and Eutrophication Potential (EP). This study found that the significant impact for the four scenarios is GWP by the contribution percentage over 72%. While EP is the second place in the contribution range of 1.70% to 5.46%, and followed by AP under 0.91%. Scenario 1 is the best scenario due to the small contribution of impact compared to other scernarios, and potentially to be applied by modification in increase of composting percentage and additional recovery gas in landfill.

Solid waste management in any large urban city like Lahore requires special disposal measures. In thisregard, Lakhodair landfill and Mehmood booti dump sites collect and handle major bulk of all the solid waste comingfrom ten towns of Lahore, with the city’s waste generation rate of being 0.84kg/capita per day. Spatial expanse of boththe sites was calculated in Arc GIS 10.3 system. The findings clearly showed that the extent of both these dump siteshad increased during 2006-2016 due to an enormous rise in solid waste generation. During 2006, the area of MehmoodBooti dump site and Lakhodair Landfill site was only 15 hectares and 17 hectares respectively. By 2016, this area hadincreased to 32 hectares and 52 hectares respectively. The mapping of these two sites can help in future researchesbased on investigating the disease patterns among people residing around these sites and by determining methaneemissions in the study area.

Solid Waste Generation

Purpose Due to the increasing population and prosperity, the generation rate of municipal solid waste (MSW) has increased significantly, resulting in serious problems on public health and the environment. Every single person in the world is affected by the municipal solid waste management (MSWM) issue. MSWM is reaching a critical level in almost all areas of the world and seeking the development of MSW strategies for a sustainable environment. This paper aims to present the existing global status of MSW generation, composition, management and related problems. Design/methodology/approach A total of 59 developed and developing countries have been grouped based on their gross national income to compare the status of various MSWM technologies among them. A total of 19 selection criteria have been discussed to select appropriate MSWM technology(s) for a city/town, which affects their applicability, operational suitability and performance. All risks and challenges arising during the life cycle of the waste to energy (WtE) project have also been discussed. This paper also gives a comparative overview of different globally accepted MSWM technologies and the present market growth of all WtE technologies. Findings It was found that most developed countries have effectively implemented the solid waste management (SWM) hierarchy and are now focusing heavily on reducing, reusing and recycling of MSW. On the other hand, SWM has become very serious in low-income and low-middle-income countries because most of the MSW openly dumps and most countries are dependent on inadequate waste infrastructure and the informal sector. There are also some other major challenges related to effective waste policies, availability of funds, appropriate technology selection and adequacy of trained people. This study clears the picture of MSW generation, composition, management strategies and policies at the worldwide context. This manuscript could be valuable for all nations around the world where effective MSWM has not yet been implemented. Originality/value This study clears the picture of solid waste generation, composition, management strategies and policies at the worldwide context. This manuscript could be valuable for all nations around the world where effective MSWM has not yet been implemented. In this study, no data was generated. All supporting data were obtained from previously published papers in journals, the outcomes of the international conferences and published reports by government organizations.

Solid waste problem is happen in many big city, such as Surabaya City. Jemur Wonosari which is participant in Surabaya Green and Clean (SGC) program also have waste management problems. When SGC was conducted, solid waste management is good. However, after the program finished, solid waste management facilities was neglected. In this research we measured solid waste measurement in waste generation and composition from domestic and non-domestic. Also to survey the level of community participation in manage solid waste. The design is quantitative research, data getting from measurement of waste generation and composition also question data to know community participation level in waste management which influenced by internal factors (knowledge, motivation, and environment attitude).The result of research, waste from people in a day is 0,093 kg/person/day. The result of solid waste generation which produced by the community is about 2054,37 kg/day. Waste composition which dominated by food waste, it’s about 43,3%. From the X2 test explain that there is a relation between knowledge, motivation, and environment attitude to community participation and between community participation to solid waste management. The community need to improve composting activities to minimize waste and rise up community participation.

Solid Waste Generation

Traditional markets are commercial areas that produce household-type solid waste so that the generation, composition, and the characteristics of the solid waste in Kepanjen Market will be different. This research is related to the reduction potential to improve solid waste management with the aim of determining the generation, composition, characteristics, collection and the transportation of the solid waste. The data used in this study include operational technical solid waste data, as well as secondary data such as area, number of traders, solid waste management resources, collection facilities, transportation routes, supporting maps. Solid waste generation calculation uses load-count analysis method. Calculation of solid waste composition uses the crossroad method. Calculation of physical characteristics includes specific gravity of solid waste. Calculation of transportation of solid waste uses the Hauled Container System method. Mass balance is analyzed using recovery factor values. The results of the analysis show that the solid waste generation average is 2.94 m3/day, with a specific gravity of 190.03 kg/m3. The highest composition of solid waste is food solid waste by 28.67% and vegetable and fruit solid waste by 22.67%. These components can be used as compost raw materials. The potential reduction with the mass balance method shows that the residue is 201.49 kg/day, reduction scenario can reduce solid waste by 36.06% of the total load that must be transported to the Final Processing Site. The solid waste transport result with the capacity/size of 6-10 m3 of a transport vehicle (arm roll truck) shows that the effective working hours for 8 hours can pick up the solid waste in 1 trip, and the transport fleet can serve other markets.

The large and increasing amounts of municipal solid waste (MSW) generated each year in several industrialised countries have raised concerns on the economic viability and environmental acceptability of the current generation activities. The planning of an optimal regional waste management strategy requires a reliable tool for predicting the amount and the corresponding composition of MSW likely to be produced. Furthermore, for integrated solid waste management, direct and indirect participation of local government's authority is essential. This paper focuses on the existing waste management characteristics of selected local authorities in Malaysia. As a case study, the research considers three local authorities in Selangor State, namely Selayang, Klang and Subang Jaya. This research further identifies the issues concerning the enviromnental effects due to indiscriminate solid waste disposal. The findings of the study are expected to provide useful guidelines to the MSW policy makers.

<span lang="EN-MY">Maintaining current municipal solid waste management (MSWM) for the next ten years would not be efficient anymore as it has brought many environmental issues such as air pollution. This project has proposed Artificial Neural Network (ANN) based prediction algorithm that can forecast Solid Waste Generation (SWG) based on population growth factor. This study uses Malaysian population as sample size and the data for weight is acquired via authorized Malaysia statistics’ websites. All data will be normalized in the pre-processing stage before proceeding to the prediction using Visual Gene Developer. This project evaluated the performance using R<sup>2</sup> value. Two hidden layers with ten and five nodes were used respectively. The result portrayed that there will be an increase of 29.03 percent of SWG in year 2031 compared to 2012. The limitation to this study is that the data was not based on real time as it was restricted by the government.</span>
