Processing Plants

e-Waste is generated at the staggering rate of 6.1 kg per person. In 2016, 44.7 million tonnes was generated globally, and the amount is estimated to reach 52 million tonnes annually by 2021. The management of this huge quantity of e-waste is a major problem across the world, primarily in developing countries. An effective e-waste management system is linked to the sustainability of e-waste processing plants, and currently it is plagued with different supply chain network (SCN) issues. To address the issues and challenges of SCN, there is a need to prioritize and address the constructs. The study thus combines two multiple criteria decision making (MCDM) tools, the analytical hierarchy process (AHP) and quality function deployment, to prioritize the constructs identified from literature and supported by field studies. The house of quality (HOQ) has been used for analyzing different stakeholders’ requirements. The degree of importance for HOQ-1 has been derived using the AHP tool. The study revealed the most intriguing issues and challenges of e-waste processing plants considering the requirements of different stakeholders. The results showed formal collection, storage, semi-informal collection, and e-waste quality to be the major issues of processing plants. The findings obtained from MCDM analysis have been validated though two case studies in India and China. If the results obtained are applied to the existing e-waste SCN, a holistic e-waste management system can be achieved for developing countries.

Solid waste management is one of the developmental challenges facing city authorities worldwide, especially in most developing countries. Rapid urbanization has made solid waste management a serious problem in poor and developing countries. This study aims to analyze the determinants of willingness to pay for improved solid waste management system. For this purpose, two hundred and seventeen Households were selected in Lekhnath, Kaski, Nepal. Pre-structured questionnaire was used to collect the data. Data was collected by using systematic random sampling techniques. Multiple Linear Regression analysis was used to find the determinants of willingness to pay for improved solid waste management system. The tentative average wastes produced per day from their house is one kilogram with minimum one hundred gram and maximum ten kilogram per day. Main disposal method/site for solid waste management of majority of the respondents is Burn followed by cannal, near open places, send in waste management vehicle, road side and rivulets. Almost all of the respondents are not satisfied with the community responsible for solid waste management in the study area. The average amount that the respondents have willingness to pay for solid waste management system is Rs 56.84 per month. Further, it is found that Having any member abroad, Remittance received in last one year and House ownership are the major determining factors for willingness to pay for improved solid waste management system in the study area. However, other factors like Sex of the respondents, age of the respondents, family size, Family type, Caste/ethnicity, education of the respondents, Total number of employed person at home, Total number of literate person at home, Major occupation of the respondents, tentative weight of accumulated solid waste per day, Monthly Income of household, Visit at any hotel/restaurant during last 12 months, and Having any livestock at household do not have any significant impact on willingness to pay for improved solid waste management system. Janapriya Journal of Interdisciplinary Studies, Vol. 6 (December 2017)

AbstrakBerbagai macam upaya dilakukan oleh pemerintah untuk menciptakan lingkungan suatu kota yang bersih, diantaranya melalui penyediaan fasilitas sistem pemrosesan sampah sebagai tahapan akhir dalam pengelolaan sampah. Saat ini, Kabupaten Klungkung, Provinsi Bali memiliki 3 alternatif sistem pemrosesan sampah yang dapat diaplikasikan, yaitu: menggunakan tempat pemrosesan akhir sampah (TPA) eksisting Regional Bangli, membangun TPA baru tersendiri untuk Klungkung, dan pemrosesan akhir di Tempat Olah Sampah Setempat (TOSS). Penelitian ini bertujuan untuk memilih sistem pemrosesan sampah yang paling optimal dengan mempertimbangkan 4 kriteria, yaitu lingkungan, ekonomi, sosial dan teknis (analisis multikriteria) dengan menggunakan pendekatan Analytical Hierarchy Process (AHP). Setiap kriteria memiliki beberapa sub kriteria yang dimintakan kepada 35 orang responden yang mewakili 5 institusi pemerintahan daerah terkait untuk dilakukan penilaian perbandingan berpasangan. Penilaian juga dilakukan untuk mengevaluasi setiap alternatif terhadap semua sub kriteria dan kriteria. Secara global, responden lebih memilih pencegahan pencemaran lingkungan (nilai bobot 0,16) sebagai sub kriteria terpenting dari total 13 sub kriteria yang tersedia. Urutan kriteria yang dianggap lebih penting adalah lingkungan (nilai bobot 0,543), sosial (0,181), ekonomi (0,146) dan teknis (0,130). Untuk alternatif pengolahan sampah di fasilitas TOSS dianggap yang paling optimal (total nilai 0,47) disusul TPA Regional Bangli (0,28), terakhir TPA baru (0,25). Suatu alternatif sistem pemrosesan sampah dengan kelebihan dan kekurangan masing-masing harus dipilih yang paling dapat diterima oleh berbagai stakeholder terkait sehingga diharapkan dapat menjadi bagian dari suatu sistem pengelolaan sampah yang berkelanjutan dari suatu kota.AbstractIn order to create a city clean, efforts are taken by government including provision of waste processing system facility as part of waste management system. Recently, Klungkung Regency, Bali Province has 3 alternatives of waste processing system to be applied, namely: utilizing the existing regional final disposal site (TPA) of Bangli, building a new TPA facility dedicated for Klungkung area only, and on-site waste processing facility (TOSS). The study aims to determine the most optimal of waste processing system by considering 4 criteria, namely environment, economic, social and technical (multicriteria analysis) with the help of Analytical Hierarchy Process (AHP). Each criterion having several sub criterions were assessed by 35 respondents representing 5 local government’s institutions by applying pair wise comparison. The asessement were also performed to evaluate the alternatives to the given criteria and sub criterion. In global, respondents preferred to put environmental pollution prevention (weight of 0.16) as the most important among total 13 sub criterions available. Among the criteria, environment (weight of 0.543) was more prioritized than social (0.181), economic (0.146) and technical (0.130) aspects. Other result showed that TOSS (total value of 0.47) was more preferred than existing TPA of Bangli (0.28), and new TPA of Klungkung (0.25). An alternative of waste processing with its advantages and disadvantages should be chosen and acceptable by the related stakeholders, thus the facility becomes part of sustainable waste management system in a city.

Waste Management System

Waste management is a systematic, comprehensive, sustainable activity that includes waste reduction and handling. The existence of waste can have a health effect on the environment and society if it is not handled seriously. The influence of waste on the environment that can damage the aesthetics of the environment and for health can indirectly be in the form of vector-borne diseases that breed in the waste. This study was conducted to determine the description of the waste management system in Soe City. The research method used is a descriptive survey where the research is carried out with the main aim of making a picture or description of a situation objectively. The number of samples in this study were 26 TPS and 1 TPA and the managers of each TPS and TPA. The analysis used is univariate analysis. Based on the results of the study, it showed that of the total 26 TPS in Soe City, 3 (11.5%) were in the good category, while 23 (88.5%) were in the bad category. The waste management system that starts from waste sorting is 26 (100.0%) TPS is bad in sorting waste, bad waste collection is 17 (65.4%) while good is 9 TPS (34.6%). The process of transporting waste from TPS to TPA is still bad at 17 (65.4%) TPS and 9 (34.6%) TPS have good category, for waste processing from 26 TPS no one does waste processing, and final waste processing Soe City TPA is still bad at destroying waste. The Soe City Government is expected to pay attention to waste management issues as well as support and facilitate the solid waste management system in Soe City, in order to reduce the negative impact on environmental health and public health

Municipal Waste Management

<p>Implementing a structured municipal waste management system in urban spatial context revolves around integrated municipal solid waste system (IMSWM) that comprised all major actions in waste management. The institutional structure of IMSWM entails a much wider scope of responsibility that marked a departure from the traditional municipal waste management system that seeks to reduce risk to public health by removing waste from homes and cities to the landfill. Integrated waste management incorporates, in addition to reducing risk to public health and the environment, resource conservation and material recovery that promotes social inclusiveness and urban sustainability. The economic implication of implementing a balanced structured MSMW is enormous; not only in terms of financial burdens on the government but also the revenue it generates for local economy and its macroeconomic effects. This study makes use of secondary data and compares municipal waste management systems operated in three developing countries by looking at MWM strategy that optimizes economic efficiency and promotes sustainable development in urban cities that can be applicable to other developing countries.</p>

ABSTRACTIn order to create a city clean, efforts are taken by the government, including the provision of waste processing system facilities as part of a waste management system. Recently, Klungkung Regency, Bali Province, has three alternatives waste processing systems to be applied, namely: utilizing the existing regional final disposal site (TPA) of Bangli, building a new TPA facility dedicated to Klungkung area only, and communal waste processing facility. The study aims to determine the most optimal waste processing system by considering four criteria (multicriteria) with the Analytical Hierarchy Process (AHP) from 35 respondents representing five local government institutions. Among the criteria, environment (weight of 0.543) was more prioritized than social (0.181), financial (0.146) and technical (0.130) aspects. Respondents preferred to put environmental pollution prevention (weight of 0.16) as the most important among 13 sub-criteria. Other results showed that TOSS (total value of 0.47) was more preferred than the existing TPA of Bangli (0.28) and new the TPA of Klungkung (0.25). An alternative waste processing with its advantages and disadvantages should be chosen and acceptable by the related stakeholders. Thus, the facility becomes part of a sustainable waste management system in a city.Keywords: multicriteria analysis, pair wise comparison, analytical hierarcy process, waste processing systemABSTRAKBerbagai macam upaya dilakukan oleh pemerintah untuk menciptakan lingkungan suatu kota yang bersih, diantaranya melalui penyediaan fasilitas sistem pemrosesan sampah sebagai tahapan akhir dalam pengelolaan sampah.

Smart connected devices are emerging from the internet today. These devices are embedded with intelligence due to the development in technology. These intelligent (smart) devices are capable of interacting with humans and other smart devices, which has led to the development of “Internet of Things” (IoT). The environment can be made smart and self-aware by the direct communication between more and more devices that are part of the IoT. The IoT concept can be applied to design a smart waste management system that makes the environment clean. A smart cities project has been initiated in most developing countries. Waste management is one of the prime components of the smart city. Garbage bins can be made intelligent, so that the fill level of the bins can be sensed, and the waste can be collected. This system will minimize the time and the cost of collecting waste.
