The Impact

Incineration is the main way to dispose the municipal solid waste (MSW) in Taiwan. The amount of MSW is rapidly decreased during recent 10 years due to the policies implementation of waste reduction and resource recycle since 2003. Assessment of incinerator operation stop and transformation therefore becomes an essential issue. An evaluation framework was constructed and put into practice in this research. With the considerations of service status, operation performance, MSW treatment status and the impact level of stopping operation was integrated and assessed in the first stage. An optimal model was built for re-programming the MSW clean strategies of original service areas by taking account of MSW collection distance, design capacity of incinerators and the heating value of solid waste in the second stage. A case study was implemented for four incinerators in Kaohsiung City of southern Taiwan to demonstrate the feasibility of proposed assessment framework.

ABSTRAKKota Cimahi merupakan salah satu kota di Jawa Barat yang masih menghadapi permasalahan persampahan, seperti terbatasnya penerapan kegiatan pemilahan sampah, terbatasnya jumlah Tempat Penampungan Sementara (TPS), terjadi pembuangan sampah secara sembarangan ke sungai, terdapat penanganan sampah dengan cara dibakar dan ditimbun, dan lain-lain. Dalam menindaklanjuti berbagai permasalahan sampah tersebut serta mencapai target 30% pengurangan sampah yang ditentukan oleh Kebijakan Strategis Nasional (Jakstranas), maka diperlukan suatu instrumen yang mampu menganalisis area berisiko berdasarkan tingkat risiko persampahan per kelurahan di Kota Cimahi. Area berisiko tersebut digambarkan dalam bentuk peta dengan mengacu pada pedoman Strategi Sanitasi Kabupanen/Kota (SSK) 2018. Area berisiko dinilai melalui skor 1 s.d. 4 secara berturut-turut untuk risiko sangat rendah, rendah, tinggi, dan sangat tinggi. Skor tersebut diperoleh dengan mengalikan parameter Impact dan parameter Exposure. Hasil penelitian ini menunjukkan terdapat tiga kelurahan dengan risiko persampahan sangat tinggi, yaitu Kelurahan Cibeureum, Setiamanah, dan Padasuka serta satu kelurahan dengan risiko persampahan tinggi, yaitu Kelurahan Melong. Penambahan jumlah unit pengolahan direkomendasikan di beberapa kelurahan sehingga terjadi perubahan skor area berisiko.Kata Kunci: Kota Cimahi, Peta Area Berisiko, Persampahan ABSTRACTCimahi City is one of the cities in West Java that still faces solid waste problems, such as the limited implementation of waste sorting activities, the limited number of temporary shelter sites, the indiscriminate waste disposal on river, open burning of solid waste, etc. In following up on these various waste problems and achieving the target of 30% waste reduction determined by the National Strategic Policy, an instrument is needed to analyze risk areas based on the level of risk of solid waste per village in Cimahi City. These risk areas are depicted in the form of maps by referring to the 2018 District/City Sanitation Strategy Guidelines. Risk areas are assessed through a score of 1 s.d. 4 for very low, low, high and very high risks. The score is obtained by multiplying the Impact parameters and Exposure parameters. The results of this study indicate that there are three villages with very high risk of solid waste, namely Kelurahan Cibeureum, Setiamanah, and Padasuka and one village with high risk of solid waste, namely Kelurahan Melong. The addition of the number of processing units was recommended in several villages so that changes in the score of risk areas occurred. Keyword: Cimahi City, Map of Risk Areas, Waste Solid

The Impact

In order to research the impact of the structure parameters of mechanical grate on MSW(Municipal Solid Waste) movement characteristics such as transportation speed, average stop time and mixed rate of waste, a kind of mechanical grate cold experimental device has been designed. This device can realize the switch between push forward and backward. Many structure parameters can be adjusted such as the height of grate, move distance of grate, bed angle, and move speed of the grate. Based on Mechanical grate cold experimental device, to study the impact of the mechanical grate structure parameters on the characteristics of waste movement is conducive to applying the results of test to the actual MSW grate incinerator. It provides a strong basis for the improvement and optimization of the mechanical grate furnace in terms of characteristics of Chinese MSW.

Operation Cost

Garbage collection is an important part of municipal engineering. An effective service network design can help to reduce the municipal operation cost and improve its service level. In this paper, we propose an optimization model for the network design of municipal solid waste (MSW) collection in the Nanjing Jiangbei new area. The problem was formulated as a mixed integer nonlinear programming (MINLP) model with an emphasis on minimizing the annual operation cost. The model simultaneously decides on the optimal number of refuse transfer stations (RTSs), determines the relative size and location for each RTS, allocates each community to a specific RTS, and finally identifies the annual operation cost and service level for the optimal scenario as well as other scenarios. A custom solution procedure which hybrids an enumeration rule and a genetic algorithm was designed to solve the proposed model. A sensitivity analysis was also conducted to illustrate the impact of changes in parameters on the optimality of the proposed model. Test results revealed that our model could provide tangible policy recommendations for managing the MSW collection.

The Impact

After the airport is put into operation, a large amount of wastes generated every day will bring waste disposal pressure and ecological environment pressure to the airport and surrounding areas. This article expounds the current methods of airport waste disposal. According to the principle of waste reduction, harmless and reclamation, a set of solid waste gasification methods suitable for airports are proposed, which can reduce waste transportation and landfill costs, effectively control the impact of environmental pollution. At the same time, it can use waste heat to generate electricity to turn wastes into treasure and promote green airport construction.
